If the Windows update installation is truly frozen, you have no other choice but to hard-reboot. Depending on how Windows and BIOS/UEFI are configured, you might have to hold down the power button for several seconds before the computer will turn off. On a tablet or laptop, removing the battery may be necessary.Apr 6, 2023

How to Fix a Stuck Windows Update - Lifewire

More specifically, holding down the power button on a computer for at least 5 seconds will sht it down. When you press the power button to start it up again, let it do what it needs to. Hopefully it will un-do the changes it attempted to make and everything will be fine again. I've seen this happen only a handful of times when Ive worked on clients computers, and its always a bit worrying, but it usually fixes itself..

If it doesnt work, one thing you can try, is while the computer is starting up, hold down the F8 key. You should see a black and white screen with text and a list of options.. one of them should say something along the lines of "Last Known Good Configuration", use the arrow keys to highlight it and press enter. That will load the last saved system settings and hopefully will get you going as well

Have you tried pressing space bar (maybe its in hibernation mode) ?

or try holding power button for a few seconds (10) then turn it back on.

as a last resort you could try take the battery out, disconnect it from the power adapter, hold down the power button for 30 seconds and then place the battery back in and the power adapter and try powering it on?

What version of Windows is this? I am going to assume Vista/7...
Even though it's not recommended to power off the computer while it's updating, I have done this several times when they are stuck for hours.

If you want to risk it, Hold the power button down for 5-7 seconds and the computer will have it's power cut. Wait another 30 seconds after the power down and start it back up. It should start installing updates procedure again. In my experience, it usually works after this. It still can take some time though, so be patient.

Bro check your hardware power management system to adjust all your power configurations.

Oh dear that's the worst thing that can happen during a bios update. the bios chip is probably now useless rendering the laptop useless. You will need a new motherboard I am afraid to say.

start on safe mode and use recovery mode next time do not close before it completly updated

reboot it! guranteed vista issue
just press and hold the power button shut it down then reboot it and it will finish....

Did you try Last Known Good Configuration?

try this if ur notebook shows a little sign of life....


or else
1. unplug the laptop
2.take out the battery
3.hold down the power button for 20 seconds (doing this drains any excess power fron the unit)
4.put battery back in
5.plug in laptop
6.try to turn it on

All the best

Have a nice day!
