        Hello I was applying updated today and notice that when one of the update

        completed, the update did a restart the os shutdown ok but the BIOS never

        kicked in to restart the computer


        The screen was black, but there was power in the system ( the power button

        still was on ) I had to force the computer to power down then have it

        start up and the updates continued


        Is there any way to debug this issue? or how to fix it?

        Please, explain what version of Windows are you using and, preferably, also which updates you installed before you had this problem. Others might be able to answer once they know that.

        Windows 7 Professional, SP1, x64 Group W (ex B) & macOS + Linux (Mint)

        Hello —

        Thanks for the reply — –

        I first noticed it when  win10 /1809 was updating ( it an hp laptop — they took their time
        getting 1809 out there )

        As noted, after  each reboot that 1809 did, I had to power down / power up to get it
        to continue —  other than the human interaction, the update to 1809 was OK

          Laptops are generally set to use so-called “Fast Startup” for Window 8 and later which is actually similar to the hybrid sleep (“hibernate”) mode of earlier Windows versions.  You might want to try disabling that (see this How-To Geek article) at least temporarily to see if that makes a difference.  It shouldn’t affect reboots, but strange things can happen with OS updates, especially if they include microcode patches.

          If that doesn’t help, you might also want to check all settings in the system’s UEFI-BIOS.  The methods for getting into that vary considerably among system OEMs; so you may need to look for details in your system’s user guide.  Or provide some additional info on the model, et cetera, and we’ll try to help.

            Some HP computers can accept pressing the escape key on power-up until you see a message that says something like “startup interrupted”, a menu should appear with further instructions.

        … since it seems to start the restart procedure but doesn’t seem to complete the shutdown, or trigger the reset and bootup… I’d suspect that the power management driver may be having problems.

        Drivers dropping out would, annoyingly, be somewhat typical of Windows 10 feature updates.

        I’d suggest reinstalling the manufacturer-provided official drivers. Yes, even if there’s an application that’s supposed to help you with them and it says there’s no new driver versions to install.

        Mind you, how long did you wait at the black screen / power on state? In an extreme case I had that part last for 2 hours once and the process completed eventually by itself anyway. Though that was before Windows 10…

        I, too, have had the same problem with my HP Pavilion desktop computer.  When restarting the computer, the computer begins the shutdown process, but will not re-boot.  The power is still on and the screen remains dark, but no hard drive activity.  This is intermittent as sometimes it will reboot fully.  But most of the time, I have to power down completely several times before the boot sequence begins.  This started about the same time frame as fpefpe above and I was running Win 7  Home.  I have since upgraded to Win 10 Home 1903 and hoped this would solve the problem.  It did not.

        Any suggestions to solve this problem would be most appreciated.

          I don’t know the specific reason, but there’s a good general-purpose response: Have you checked to make sure you have the latest firmware? HP’s site should guide you to it, although you’ll need the machine’s model number.

        I haven’t tried getting the latest firmware from HP’s site.  But will do so.

        Thanks again.
