Power Settings Suddenly Adds Hibernate Setting

Topic

New Reply

I am running Win 10 Pro V 21H2 on a new laptop. For the first month, it would go to sleep after closing the lid and remain asleep overnight (making sure that the battery was charged). In the past few days, I’ve noticed that it does sleep, but then in the morning, it seems to be in hibernation – and needs several minutes to resume – not sleep.

I haven’t made any changes to the sleep function besides changing the amount of time before it does sleep on power and battery, yet now when I look at the power options, it often says sleep after 90 minutes on battery – when it didn’t have that setting before – thus the hibernation during the night. I have reset that to Never – yet it seems to revert to 90 minutes, so I need to keep checking it to reset it – never being sure it will actually “take” the setting.

I also am now seeing that the option to “Change Settings that are Currently Unavailable” that was there, is now gone. Hibernate is not listed in the shut down options, so I am not sure why this issue has cropped up. But it is very annoying to find the laptop hibernating in the morning – no matter what I try to change that power option setting to.

Any ideas on why this may have suddenly happened?

You might try powercfg -h off in admin command prompt which will disable hibernation and fast startup

I get “C:\Windows\system32>Invalid Parameters — try “/?” for help” when I try that command. I did run CMD as an administrator, but it won’t take that.

ETA – Tried it again and it did work. No hibernate option now in the power options. I’ll see if it does it again in 90 minutes.

Thanks!

Do a reboot for good measure

So far so good – slept all night! Thanks!

I assume if I ever did want to use hibernate, it would be powercfg -h on??

I always hibernate my machines and it only takes 20 seconds to resume.
Do you have a spinning HDD in the laptop?

cheers, Paul

I have a 512 GB SSD, so that isn’t the issue. And it probably only took about a minute to resume – not immediate like Sleep.

I’ve never used Hibernate and when it started hibernating without me having done anything, and resetting the Power Option to 90 minutes no matter what I changed it to, I just wanted a way to really turn it off.

What is the advantage of hibernate, since I’ve never used it on any of my machines?

Thanks!

Sleep needs to use the battery to maintain the state so you need to charge it more often.
Sleep resumes faster than hibernate – hibernate and powered off have about the same start time.

If you use the machine daily, sleep is fine, but if you go on holiday for a week and leave the machine, hibernate may be better.

Thanks for the explanation. I think Sleep is fine for what I do – and if I were to ever leave the laptop for more than a day, I’d probably just turn it off.

Thanks again!

FWIW, IMHO I always turn my machines off over night. With SSDs the startup is so fast that it isn’t really an issue and Windows just works better if it is shutdown and allowed to clean things up in the process.

Good advice – maybe I should just try doing this for a few days and seeing how it works! Thanks!

If you disable the hiberfile (powercfg -h off), I believe hibernation AND sleep are unavailable. Sleep uses the hiberfile.

I think that is only true for hybrid sleep. I have hibernation disabled, no hiberfil.sys file and my machine still has sleep available.

Mine, too. Since I made the change to powercfg -h off, mine has been back to its old behavior of sleeping when I close the lid and staying asleep for as long as I want. No hibernate choices in the power options box or the shut down menu.
