      Yes, I set to turn off screen and sleep after 20 minutes (10 minutes if on battery). Hibernation enabled but rarely used. Never had any trouble with sleep or fast startup, but I do restart at least every 3 days. In an office setting, I think everyone should lock with Win+L when they walk away.

      The default fast startup can become an issue in an office if computers are rarely restarted, because minor problems can linger. I persuaded staff to occasionally use Shift+Shutdown at the end of their day, instead of just Shutdown; so that fast startup is not used on the next startup, which is as good as a restart.

      No I turn my computers on / off as needed. It is safer that way I feel.

      Hibernation ans sleep are the first things I disable after a new installation.

      Long ago I found a problem with hibernate so always shut it off with in admin terminal
      powercfg.exe -h off .

      I am surprised and concerned that you also disallow sleep, so just turned that off in power settings. Did recently have a situation where laptop would not wake up and had to force power off.

      I have it set to shut off display at 5 min and also set screen saver to none and 5 min and lock when starting back up.

      I normally leave my laptop on overnight but with “nothing” running.

      I used hibernation regularly when I was working, as I was driving between locations, average thirty minutes, and had several to visit during the course of the day.  I was running Windows 7 Pro, and never had any issues.  I never used sleep, and had it disabled.  My laptop would hibernate when I closed the lid.

      It is the same Dell Latitude E5420 that is running Windows 11 Pro 23H2 today, but I don’t use hibernation anymore.  It’s either on or off.  My desktop and NAS, on the other hand, are never off, just signed off so that Task Scheduler can do the housekeeping, routine maintenance and regular drive images.

      Always create a fresh drive image before making system changes/Windows updates; you may need to start over!

      Talked with my IT department last week. Complained that sleep didn’t work on my ultra portable Dell laptop. They explained to me that they disabled sleep to ensure the computer would be awake for updates. I told them that the $3,000 computer became excessively HOT in my briefcase when moving from place to place. They replied that I needed to shut the computer off every time I moved it. So…Microsoft wants it on and tied to the internet 24/7/365 and my IT department wants me to turn it off every time it moves. Go figure.

      I always shut my computers down at night.  One never knows who or what is creeping around the Internet at night.

      This argument has been going on for a very long time, even when there wasn’t an Internet as we know it now.

      Yes. The computer is set to Sleep, Wake Up, and Shut Down on its own. It’s currently a problem on a brand new Windows 11 box that it won’t wake up at the right times to run an important program.

      Do you put your computer to sleep?

      Never (nor hibernation). I put my laptop’s display to sleep.

    • #2600416

      I have hibernation and sleep completely disable on my computers. If I’m using them, they’re on. If I’m not using them, they’re off – including the UPS or power stips they’re plugged into.

      Three reasons:

      First, I’m retired so have a near zero need to lock or sleep my computers if I get up to make a cup of coffee or answer the phone.

      Second, I do not want my computers to be connected 24/7 via Intel’s Management Engine – which is three rings below the kernel, on a seperate microprocessor, runs as long as the computer has battery or wall power connected, has direct access to the ethernet controller, has shown security vulnerabilities, etc. (https://en.wikipedia.org/wiki/Intel_Management_Engine)  I prefer not to have MS waking up my computer at night and doing updates or whatever. “I’d rather do it myself.”

      Third, I prefer to disable as many “energy vampires” in my home as possible. Keeps money in my pocket and less carbon in the air. https://www.electricrate.com/data-center/what-is-phantom-energy/

      Displays (4 – 27″ screens) Stand-by after 15 minutes, or if I’m leaving the room for a while manually stand-by with a keyboard shortcut or icon double click using Sysinternals “PsShutdown” tool.

      Overnight always full shutdown power off after updating image backups with duplicates synced to 3 other external SSDs (four total). Yeah, overkill, but I hate data losses so I chalk it up as personal POM.

      No, I never use sleep mode or hibernation on my desktop PC. It can cause more harm than good.

      After clean Windows installation I always disable sleep mode and fast boot in power managment and after PC restart I use command (powercfg -h off) to remove hibernation file.

      Sleep mode/hibernation mode has no usage these days, when anyone has SSD.

    • #2600448

      I disable sleep and hibernation. Lock when away, and turn off the monitor at night. I have backup and maintenance jobs running in the wee hours.

    • #2600460

      I disable both sleep and hibernation. If I have my computer on, then I’m usually in front of the monitor. If I leave for an extended time, then I prefer to shut it down entirely.

      On my previous computer (running Win10) I used to keep sleep enabled, but the system more often than not failed to recover from sleep which required a forced reset. Also, hibernation uses several GB of disk space for the hibernation files: found out just how many after noticing that suddenly used disk space had increased for no apparent reason. Took me a while to figure out the reason and since I don’t have use for hibernation, I saw no reason for it to keep taking over disk space and decided to disable the feature entirely.

    • #2600474

      Never. Not at home nor work. The screen turns off after 20 minutes inactivity and that’s it. There were times it took a while for a pc to start, but startup-times have dwindled over the years. The most problematic thing of sleep is people leave applications running. And with shared (open) files, this could be a problem. So if you leave the office, just shut down your pc.

      I have one desktop I put to sleep at night; I can go days between reboots. I haven’t had any problems from doing it for years (probably two or three PCs ago). My other desktop is on 24/7. Neither desktop has the hibernate option; but the last one that did have both options I always used sleep, never hibernate. My laptop isn’t used regularly, so it goes off when I’m done with it. The desktops are Dell Precision (a 5820 and a 3620) and the laptop is a Dell Latitude 5590, all running W10 22H2.

      Hey Y’all,

      All 4 computers in the house have Hibernation turned off (which takes out Fast Start) and are shut down at a minimum of every night before bed. Don’t use sleep but power plans are set to turn off monitors after 1 hour.

      May the Forces of good computing be with you!

      For the very reason both sleep mode and hibernation are a bit wonky I do not use either one. Whenever I setup after a reinstall of the OS or a brand new system, I disable both in the power settings. Also, I set display(s) to sleep after 15 minutes.

    • #2600500

      Eight-year-old Dell XPS 8700 always on 24 7 365 but screen goes to sleep eventually. Lenovo thinkpad X1 laptop, goes to sleep when closing lid or after so many minutes on battery, never has issue waking up. Definitely have seen on other brands of windows 10 computers that sleep or hibernate has just never been 100% reliable.  I feel like Windows 7 sleep or hibernate was better than Windows 10 and Windows 11.   In this day and age of power efficient power supplies especially from Dell OptiPlex, and similar models, along with SSD that leaving things always on is acceptable trade-off.  Office staff need to come to work with assurance that their desktop computer will instantly be available and not have to fiddle around with waking from sleep or other problems.

      Over 23 years and MS still has not fixed sleep/hibernation, this shows how clueless MS is.

      I have start to disable sleep/hibernation since around 2000 or so. It has always been a problem. MS never care to fix it. It was an issue when had 3000-4000 PC not working correctly and getting calls from non-techy savvy people that computer not working. It became a normal part to disable it and have 1 less thing to deal with it. At work, have a script to turn off all PC after none using it for 1 hour. This cause people that work at home and did not work to call IT and say my computer turn off. Well genius you were not working since it was. Boss forced us to increase it to 2 hours but this shows how many people do not work when they say they work.

      My home computer is on when I am using it and off when I am not using it.

    • #2600539

      I advocate for the use of sleep mode especially.  Hibernate I find useful for specific people, those who like to leave programs open to remember what tasks were in progress, instead of normal shutdown.  An occasional (weekly at least) real shutdown or restart is wise to clear memory.

      Sleep mode, when active, saves at least 90% and up to 99% of the power usage a computer has.  Most computers are not used at night and are inactive much of the day, and even someone who usually shuts down when done will forget and leave for breaks.  Overall, for most users sleep mode will save from half to over 90% of power usage, and is often combined with auto monitor turn-off to save even more.  For a desktop computer this can be a savings of nearly $300 a year, and even a laptop can save around $100.

      For what it’s worth, I’ve only used sleep mode on Win 7 for no more than a half hour or so.  I don’t know how it is now with Wins 10 & 11, but Win 7 sleep mode stops the hard drive, fans, and monitor. Pressing any keyboard key “wakes the computer up”.  I’m able to do the same thing with Linux Mint and have never had any problems with either.

      I should clarify that this is Sleep Mode that I use, not Hibernation. I’ve never had a need to use Hibernation.  I also do not leave any programs running when I go into Sleep mode with either OS.

    • #2600555

      Never used Sleep mode (introduced in Windows 95 as “suspend”) nor Hibernate (introduced in Windows ME) even on the various laptops I’ve used over the years.

      If I’m awake and nearby, my current desktop PC is always powered on, no sleep/no hibernate/no power time outs, and if I leave the house for an extended period, or when I go to sleep, it’s always powered off.

      Before I retired, I regularly used a password protected screen saver whenever I had to depart the immediate area of my business PC, but I never used sleep/hibernate modes… our company required all PC be left powered on 24/7 (except under very special circumstances) so the IT dept could apply updates “after hours”.

    • #2600562

      I always leave my two desktop computers powered on for convenience so they can be used at any moment. However their dual screens are set to turn off after 1 hour of inactivity as well as lock the computer. The only time the computers are powered off is to take a system image (via a bootable USB drive) or every two months to open up the computer case and clean out built up dust or when I plan to be away from home for an extended period (ex. vacation). Otherwise I never use sleep or hibernation.

      Since they are always powered on, each desktop is connected to a high capacity (ex. 1375VA) UPS/battery backup surge protector for protection from power blips/minor outages. They are also always connected behind a hardware firewall router for protection from the Internet (blocks all incoming connections).

      Also keeping them always powered on is not for any software updates. Instead, any kind of automatic updates (OS or applications) are always turned off and updates installed manually. I want complete control over my systems to know exactly what has been done to them and when.

    • #2600567

      With SSDs and fast bootup times, no real need for hibernate nowadays.
      As you said, it rarely wakes back up properly. Whenever I’ve used it in the past I found I always needed to Restart shortly afterwards.

    • #2600560


      This has been an ongoing question for a long time. Should you or should you not turn off your computer after a day’s use. Should you hibernate or sleep the computer?

      Since Win 8.1 up to now Win 10 Pro, I have put my computer on hibernate at the end of the day. Press the power button to restart where I left off in the morning. I also use hibernate during the day when I leave my computer for an hour or more. I also turn off web access, i.e. the router. Every now and then I do a hard re boot.

      I have never had any type of problem using this method with Win 8 or 10.

    • #2600588

      Main System (laptop, using external monitor only): Screen off after 20 minutes, sleep manually engaged when I step away/out  for more than brief periods. Hibernation & hybrid sleep disabled. I shut down either when certain I’m done for the day or at least a couple times a week.

      The other laptop that’s connected to an A/V receiver > 4k TV for couch surfing/streaming gets shut off at the end of every evening. If I try to use sleep on it and then change inputs/turn off the receiver, it sort of loses the plot on the differing screen resolutions, magnification settings between it’s own screen and the TV if I switch inputs or when turning the receiver back on.

      Haven’t really tried out sleep on the rather nice desktop I intend to migrate to as new main system during the “get nothing done” days at the end of the year, just been turning it off when done with whatever specific task I turned it on for. Now I’ll test it out.

    • #2600612

      I sleep my Win10 upgraded to Win11 laptop all the time and tend to forget Windows needs to be shut down occasionally, hence every couple of blue moons it crashes during sleep. Other than that, I keep the laptop on hand for research. It comes out of sleep far faster than a cold start.

      My Windows 7 tower used to crash far more frequently when sleeping.

    • #2600630

      I have two desktops at home, and have never used sleep or hibernate because I’ve always read that they don’t work reliably. Also, I turn both computers and monitors off at night or if I’m going out for more than say half an hour.  I was brought up not to leave unnecessary appliances on when they are not being attended because of the fire risk, and that continues to represent the UK Fire Service’s advice today. I’m certainly glad that I was around when my computer’s liquid cooler blew a few years ago.

      I used to use screensavers but they caused problems sometimes and I haven’t used them for years. Similarly I used to turn the monitors off when they were the kind that resulted in static images being burnt onto the screen, but these days I leave them on all the time I have the computers on.

      The one issue I have coming up is the forced switchover from a landline phone plugged into the wall socket with Virgin Media’s form of VOIP which will mean plugging the phone into the modem which will then have to be left on 24/7 whereas I have always switched it off with the computers. This switchover is due to take place throughout the UK by the end of next year (meaning the end of local telephone exchanges) and I am gradually getting used to leaving the modem on if I go out during the day in an attempt to wean me off my old habits – but it still goes off at night!

          I’d been using my main computer for gaming and had just switched it off but left it on at the mains. I was sat at my second computer alongside it when there was a loud bang and sticky brown goo emerged from under the main computer and spread across the desk towards me. It wrecked the motherboard, memory chips and processor. The machine was 3 weeks inside the warranty so I was lucky in that respect,  although I think it also contributed to the failure of the graphics card just a few months later.

          There had been a recall of machines with a specific  batch of the coolers used at that time but when I had asked if they wanted my machine back I was assured it wasn’t in the batch – I suspect that was wrong! The recall was due to a manufacturing fault in that when the pipe was made some filings weren’t properly cleaned out and with the machine in use they moved around the cooler until they got caught up together and blocked it.

          In fairness, this was some 12 years ago, and while it has put me off liquid coolers for life I have  been assured here (by our esteemed Editor I think) that they have improved a lot since then!

            Thanks for details.  “12 years ago” is a long time in tech years, especially for mainstream liquid cooling.  I’d also agree that liquid cooling has improved a lot.  I’ve six trouble free years with liquid cooling on my desktop and would get it again.  Very little fan noise except when the CPU is under momentary high usage.  However, if I had your experience, I’d likely feel differently. Recency bias is hard to shake.

      I rarely use sleep or hibernation on any computer. Most of my computers turn the monitor off after about a half hour of inactivity; the only exception to this are the two computers on my two TVs. I don’t want them going dark while I’m watching TV!

      On occasion I have used hibernation, because it is really cool to be able to instantly power down and instantly power up to where I was when I powered down. However, I don’t do this very much, because certain things won’t work correctly after doing it — for example, if I am logged onto something, I’ll probably need to log on again after coming out of hibernation. I never use auto-hibernation or auto-sleep; I will always do it manually. The one exception to that is if the power goes out in the house, and the battery gets down to 5%, I will allow it to hibernate at that point.

      As a general rule, all computers stay on and running all the time; only the monitor goes off.

      Hi Susan,

      I agree in what you are saying, does not play well, and i even go further by doing this…

      Delete Hibernation mode in Windows 10: Open the Command Prompt as an administrator and enter powercfg.exe /hibernate off.

    • #2600632

      I turn it on about 7pm, use it and shut it down about 930 pm or so. Laptops just on when I’m using them. Then shutdown. this way i don’t have to play games to sleep it, temporarily shut the internet off.

    • #2600664

      I’m on Win 11, and have always used sleep since Win 7 on my desktop. I like that it reduces power and heat to a minimum and gives instant return to whatever I was doing. Hibernation is disabled. I’ll shut off if I’m away for a few days, and around once a week to refresh things. Any network or timed awakening is off.

      There’s a reported problem with Win 11 that it can shut off instead sleeping on a timer, I invoke it manually with the power button.

    • #2600741

      Nope.  No sleep for the wicked (at least that’s what some users probably think of their IT department).  It’s either on or off, with the screen set to an appropriate timeout / sleep value.

      Since most of our IT maintenance is done automagically in the wee hours of the overnight/morning, and some of our users are old school and were trained early on to turn off their PCs,  I’ve even had to go as far as setting some PC’s BIOS to auto power on if it’s powered off.

      This allows for that magic maintenance to happen, all so the users can hopefully have a productive day, without “we interrupt your work with an important update from IT”…

    • #2600870

      I’ve had a few HP desktop PCs over the last couple decades, but the most recent one, rather than using the legacy S3 standby (BIOS controlled), uses the “Modern Standby”/”Instant On”/S0 low power state for “Sleep” controlled by the OS in conjunction with a System-on-Chip (SOC). Apparently with pressure from MS to comply, the hardware vendors no longer provide BIOS support for the legacy (S3) Sleep state, so standby has to be managed through the OS/SOC (S0).

      I loved the old legacy standby – I never had to restart my HP machines except for monthly updates or an occasional new hardware driver. Because it takes me 10 minutes or so to setup my preferred environment when I start my machine from boot, it was *so* much better to instead return from standby in a few seconds ready to work, or put it back to Sleep in seconds knowing I could quickly pick up where I left off. Reliably, every time – I NEVER had any problems returning from standby. Even if you didn’t have reliable electric or at least a UPS, you could configure it for Hybrid standby – which would normally return from standby quickly, but if there was a power outage the machine would recover using the contingency hibernation file.

      One related thing I’d do is make sure Scheduled Tasks weren’t configured to “Wake the computer to run this task” – no waketimers, pet peave, so they’d stay sleeping until *I* woke them.

      Now with “Modern Standby” (S0) there is no Hybrid method. And every time the monitor is soft-powered off, the system goes into S0 by design. (With legacy S3 I’d often soft-power-off the monitor while keeping the system running tasks or if I wouldn’t be using it for a while. Now I have to use a jerry-rig to keep the system running when the monitor is off: either hard-power off the monitor, or run the UAP Media Player with a song on loop & the app’s sound muted – it keeps the system from going low-power.) While in S0 deep sleep (DRIPS), the System-on-CHIP (SOC) frequently polls to see whether the system should run various tasks. This is on a FAST system that could run these tasks in a split second whether it’s idle or not, in the background without breaking a sweat. What I DON’T want is the system coming out of low power state to run these tasks all day & night. I have a hybrid SSD/HDD storage; wear & tear on the HDD from all the power-cycling is really racking up in the SMART stats. Alternatively to S0, Hibernation would put wear on the SSD & be slow. Worse, new-to-S0 users don’t initially understand why their PC doesn’t go into low power standby on request (indicated by the power-light flashing or color changed, etc.) It’s often because it’s running maintenance & myriad other tasks the moment it goes “idle” before it will eventually reach low power “DRIPS”, maybe.

      By configuring specific Scheduled Tasks to not run unless there’s an internet connection, combined with disconnecting my Ethernet cable before *every* standby, I’ve been able to tame it to behave fairly similarly to legacy S3. (There’s a “Network Disconnected” setting, but it’s ignored for most purposes.) And the system by design wants to check for updates, emails, telemetry, VoIP, “news” & other distractions, etc., *frequently*. So my work-arounds usually only work until the next Windows Update or driver update causes the power cycling to go back into over-drive or worse – fail completely in reaching low power standby. Even when working well, it can vary anywhere from 10s to 5+ minutes to not-at-all reaching low power. (You can sometimes determine what blocked it by running Microsoft’s Sleep Study reporting utility & trying to decipher the cryptic codes that can’t be found anywhere online.) The only thing it attains reliably is turning the monitor off, so at least the “perception” is that the system is sleeping.

      I often end up using my slow old equipment because S3 standby on them is so much faster & more reliable. Modern Standby, for me, severely dampens my enthusiasm for an otherwise great HP desktop system. (I won’t even get into laptop systems overheating or draining the battery from Modern Standby.) I understand why S0 would be great for *some* users, but it’s not ready for prime time and the old BIOS alternative has been removed…

         Modern Standby, for me, severely dampens my enthusiasm for an otherwise great HP desktop system.

        I don’t think Modern Standby would suit me either, but I found this recent post encouraging.  It covers both disabling Modern Standby and enabling the legacy S3 sleep state.

        If you decide to try it, please post about the outcome.

          A year ago, I was shocked when I found out what had been substituted for my good old S3 standby on my shiny new machine, and that method was the first I soon tried to “revert” to S3 from S0.  Afterward, the “powercfg /a” command even indicated that I had successfully activated S3.  Unfortunately, S3 standby requires support from the BIOS/UEFI, and most of the manufacturers are no longer providing that code in their latest systems.  When I attempted to place the system into S3 standby:

          The system immediately went into 0-watt “sleep” (rather than typically taking a few seconds.)  But the power LED was still lit full time instead of its typical blinking for standby.  When I attempted to return from standby, power resumed to *some* components, but not to others, and video didn’t resume.  I was forced to hard-power off to restart.  So back to Modern Standby.  I’ve done so many “Sleep Studies” and even “Windows Performance Analyzer”  event tracing, trying to resolve the issues, but the only consistencies are inconsistencies.  I hate it for many reasons and am currently resigned to just powering down most of the time.  Giant step backward for me, as the legacy S3 had worked so perfectly for my prior systems – I hope S0 works better by the time I acquire my next system.

          By the way, some hackers developed a BIOS/EUFI supplement (required disabling Secure Boot, etc.) to add back S3 support, but it doesn’t seem advisable – for security purposes and possibility of bricking the system.

        I don’t agree that “modern standby” is not ready for prime time as far as a hardware feature. It’s how Windows uses it that needs work.

        I use Linux, which refers to “modern standby” as S2Idle (short for Suspend to Idle). Intel calls it S0ix. I usually refer to it as S2Idle, as that is the term I see the most in my OS.

        In Linux, S2idle is quite decent. When I close my Dell XPS 13’s lid, it goes into S2idle instantly, and remains there until I open the lid. No ifs, ands, or buts about it. I’ve left it in S2idle for more than a day on battery, and it is still ready to go in a moment’s notice when I open the lid. All told, it would take about two days to run a full charge down to zero.

        If Windows feels like downloading updates, it will attempt to do so, and there have been scores of reports of the laptop sitting in the bag waking, attempting to perform updates, then cooking itself and running down the battery. Laptop bags are padded, so they’re excellent insulators, keeping all that heat in, and there’s no ventilation no matter how fast the fans spin.

        When you get to where you are going, you find your laptop very hot (hopefully not damaged… at the very least it takes a toll on the battery to get that hot) and very not ready for usage like you thought it would be, with a drained battery.

        The whole point of Modern Standby, from Microsoft’s perspective, is that it can things it cannot in S3. What good is your PC to Microsoft when it is just sitting there unused?

        Modern Intel CPUs and SoCs still do support S3 for now, but the OEMs often disable it, as Dell has in the XPS 13 (9310). My Acer and Xenia both still have S3 available, and I used to select it on both on principle, but both use S2idle now. You can switch this in Windows, but it is not as simple as simply switching the option from A to B as in Linux. According to what I have read, that is supposed to require a reinstallation of Windows, but I think there are workarounds to avoid that.

          @Ascaris, I admit that sleep states are a gap in my knowledge of computing. Can you (or anybody else reading this) refer me to an explanation of sleep states that is both (a) comprehensive and (b) written in layman’s terms?

          I participate in a distributed computing project, so my experience with sleep states is limited to making sure that my PCs never go to sleep. But I am curious, and the knowledge could come in handy when helping a family member with their issues.


          • #2601251

            The “traditional” sleep state is known as S3, or “suspend to RAM.” When you initiate this sleep state, it copies the system state (that is not already stored in RAM) into some of the free RAM, then turns off power for the whole system (more or less), except for the RAM. The RAM on a PC is dynamic RAM, so it has to continuously be refreshed or it will “forget” its data. That takes some power, and other bits of the motherboard need to be alive to deliver that power, but nearly everything is powered down.

            The CPU is not active in S3, so it cannot be processing anything. The system has to wake up (resume) from the sleep state in order to process any data. It can take a few seconds to resume from S3, as the system state is copied back from RAM into wherever it needs to be, and the various system devices are brought back to full power.

            For this reason, S3 would not be a good choice for a device like a phone that has to always be on, listening for calls, incoming text messages, incoming notifications from social media apps, and all kinds of stuff. If it can process that stuff while still in a partial low power state, then go back into a full low power state when that is finished, then it can have battery run times that are decent while also functioning in a way that people want.

            That is what S0ix/S2Idle/Modern Standby does. It’s a software based sleep mode (though supported by hardware based power saving), described as “Suspend to idle.” That’s what S2Idle means… it does not mean S2 in the sense of S3, which might confuse some people. S2idle actually uses S0, the fully running state of the PC.

            When suspended to idle, the system achieves a very low power state (C10, on my XPS) and puts the various system devices into a similar form of very low power operation, but without turning them off fully. They don’t need to reinitialize and have their state loaded into them after sleep, because they never went fully off. The system is still technically running unsuspended, but most of the CPU is powered off until it is needed.

            Certain processes (designated by the OS) are permitted to keep running while suspended to idle. On a phone, these are the listeners for the various notifications and such that I mentioned, as well as network connectivity. A phone, of course, has to remain connected to the cellular network in order to receive an incoming call or text.

            PCs with S2Idle can also remain connected to a wifi access point in a low power state, so that as soon as the PC needs to use that connection, it is instantly available. No connection is possible during S3, and even if it was, the CPU is powered down and unable to process any of it. It will have to handshake and re-associate with the access point after it comes out of S3.

            According to Intel, S2idle (which they call S0ix) can save as much power as S3, while allowing the PC to wake and resume internet functionality nearly instantly. If that is truly the case, there is not much reason for S3 anymore, as it takes much longer to wake and become functional again.

            The reason people still want S3, though, is that Microsoft’s implementation of S2idle is not making them happy. There are many tales of annoyance with “modern standby” across the web, with many people reporting the kinds of things that have been mentioned in this thread. When you wake the laptop to use it once again, it could wake up and have only used a small bit of its battery charge, as expected, but it could also have used a big chunk of it and roasted the PC to boot while it was in the bag.

            The S3 sleep mode, if it is available on a given model, solves this, because when the PC is sleeping, it’s not doing anything else. It can’t self-wake from a process running on the CPU, because the CPU isn’t active. The odds of the thing remaining asleep when you are not using it are much better, so it won’t be likely to waste your battery charge and cook itself while in the laptop bag. (I personally would recommend using hibernate rather than sleep when bagging the laptop, but lots of people prefer sleep… and if it works right, it should be fine.)

            In Linux setups like mine, the way the system handles S2Idle is much like S3. While the system can allow certain processes to run while suspended to idle, it doesn’t. When I put it to sleep, I am confident that it will enter sleep mode quickly and remain that way until I open the screen in order to use it again. It has yet to disappoint me in the nearly 3 years I have had the XPS (which only does S2idle sleep).

            The one exception I know about as far as remaining in the sleep state is that it will wake when it reaches the low battery threshold, at which point it will do whatever it it set to do in the power settings… in my case, to give a warning sound, then wait one minute, and if power is not connected by that point, to initiate hibernation.

            I do not know about anyone else, but I much prefer a laptop that does nothing but conserve power over a semi-sleeping laptop that is still doing wakey-wakey stuff after I told it to sleep. I do not need it listening for anything (especially if it means keeping the net connection active) while it is supposed to be sleeping and conserving my battery charge for when I next decide to use the unit. I certainly do not need it trying to install updates on its own when it is supposed to be sleeping!

      I am surprised at how many people here disable sleep mode. I use it all the time. Energy savings is nice, even if it hardly makes a difference on the bill… but on laptops that see battery use, it’s even more useful.

      I have no timers of any kind on my three main PCs (all laptops, as in my .sig). The screen will not turn off, and sleep mode will not happen without my input. If the lid is open, I am using it, so I want it to remain on. I used to leave my laptops open to save wear and tear on the hinges, but after a certain furry creature knocked two of them down and damaged each one’s LCD panel, I began closing them all the time. On any of the three, when I close it, it will either lock the session if on AC power, or initiate sleep if on battery.

      The Xenia laptop is a gaming unit, and as a relatively large and heavy unit, it does not lend itself well to daily “out and about” usage. it is my desktop replacement unit, filling the role that used to belong to my old Sandy Bridge unit. It is never really used on battery, and nearly all of the time, it remains on AC power, lid closed, with external mouse, keyboard, and display. When I am finished using it for the day, I close the lid (feline protection) and manually select sleep.

      With the Dell and Acer, I often use them on battery, and the normal usage for these is that I open the lid whenever I want to use them, which wakes it from sleep… I use it, then I close the lid, returning it to sleep. I may do that a dozen times a day, if not more, and I don’t want to wait for it to boot or resume hibernation each time, even if it is fast compared to computers of a few years ago. It’s even faster to open the lid, type in my password, and begin using it, with no perceptible wake delay.

      Leaving them running (“awake” but idle) substantially reduces the run time on battery. The Dell will idle from 100% charge to o% (not that I would ever really let it get that low) in about 18 hours, but in sleep (S2idle/S0ix/modern standby), it will go 48 hours or so.

      I never shut any of them down or reboot them routinely. No real reason to.

      Sleep is good zzzzzzzzzzz 🙂
      Hibernation on an OS SSD is a no-go in my experience.
      Maybe that’s why my 2012 OCZ SOLID SSD is still going strong as an OS drive.

        Hibernation on an OS SSD is a no-go in my experience.


        • #2601056

          Hibernation writes the current system state to the drive (hidden file hyberfil.sys)  This can entail a VERY large file, depending on RAM capacity and everything that’s currently open prior to hibernation.  Writing to SSD’s over previously written storage locations many times (more likely as the drive is filled closer to capacity, and when very large files are being written frequently) can eventually wear it out.  Not sure how long that would take, but it seems like the hibernation process would be prone to SSD wear over time.  That’s the idea anyway.

            SSDs do wear out eventually, but the rated life is so long for most of them that they would go for many, many years, even with hibernation and the virtual memory swap (or paging) file on it, and it is likely to still have life left in it well beyond the point that you would still be using it.

            If you take my Dell XPS 13’s SSD, a 2TB Samsung 990 Pro, it has a 1200 TB TBW rating (TBW meaning total bytes written, though some use it as terabytes written). The XPS 13 has 16 GB of RAM, so if that total amount is written (and not just the parts in use) five times a day, 365 days a year, for a decade, it comes out to 292 TB written. That’s only a quarter of its rated life, and it is likely that most people who use hibernate would do it a lot less often than 5 times a day, every day, including weekends and holidays, for ten years.

            Smaller SSDs can be expected to have lower write ratings, but that also means they are cheaper to acquire, and that you are more likely to want to replace them anyway (in order to get a bigger one) before they reach the rated write limit.

            It would be a little different if we were talking about a laptop that has a non-removable SSD integrated into the motherboard. The long service life still applies, but if the SSD wears out, the whole thing is shot. I would never buy or recommend such a unit unless it was truly dirt cheap. Disposable consumer electronics at full price is just a flat ‘no’ for me, and anything with non-removable consumable items is disposable, even if they last a long time.

      I don’t agree that “modern standby” is not ready for prime time as far as a hardware feature. It’s how Windows uses it that needs work.

      I agree. I think Modern Standby would be fine if Microsoft supplied just a few configuration options – for instance, control of whether the SoC checks for “activities” 24/7, or instead just allows the system to sleep undisturbed until wakened by the operator.  People have different requirements for their systems – a few options would better allow that.  I know, it’s tough for Microsoft to give up their control.

      But as a hardware feature, if drivers are properly configured, there’s no reason the system shouldn’t be able to “standby” through interaction of the OS and SoC, even without the BIOS/EUFI support.

      If Windows feels like downloading updates, it will attempt to do so, and there have been scores of reports of the laptop sitting in the bag waking, attempting to perform updates, then cooking itself and running down the battery. Laptop bags are padded, so they’re excellent insulators, keeping all that heat in, and there’s no ventilation no matter how fast the fans spin.

      Disabling wake timers should switch off the update oven effect. This disadvantage is Windows will will be slower when it updates while you use it. I get around this (and control ‘when’ by pausing update via settings so that it does not happen until the first week of the month. However I don’t wait that long. Getting towards end of month, I switch update on at a time convenient to me, let it do its thing then pause update again after restart.  If you do this, be aware that update will offer previews.  Refusing them is recommended.

        Can anyone confirm that this works? There are a ton of people out there who would like to have a solution to that issue, and if it were that simple, I would think someone would have mentioned it. If it does correct it, that’s good, though of course it shouldn’t be necessary to change settings to keep a laptop from discharging and cooking itself when idle and supposedly sleeping.

      I disabled the hibernation feature to reduce writes to the SSD.  The hibernation file equals the amount of RAM memory, so 32 GB of RAM = 32 GB of writes to the SSD for each hibernation.

      Hibernation = system state saved to storage device. Uses very little power.

      Sleep = system state saved to memory.  Uses more power than hibernation as the memory must be kept alive.

      Yes, I put two Dell PCs into SLEEP mode every morning after using them.  On a Win10PRO XPS8930, SLEEP and several other functions became unreliable.  SLEEP would wake itself up randomly, file explorer was closing itself randomly, cursor would disappear.  I was convinced that SLEEP and other stuff were corrupted in OS system files.  I decided to let the Win11 Installation Assistant take me to Win11 PRO and fix all the OS system files at the same time.  The upgrade worked, SLEEP now stays asleep until I wake it, and the other bugaboos disappeared also (cursor, file explorer).  The Win11 PRO upgrade even respected my use of a local account and never asked me to create an MS cloud account.  The other PC came with Win11 Home and there SLEEP has always worked.  I use it daily for 20+ hours each day.

      “Modern standby” is useless for people who need to wake up their computer automatically, for example in the morning. With “Modern standby” this is IMPOSSIBLE!
