      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.

      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…
