After installing Win 10 2004 - Sleep does not work.

Question

Hi, I'm having a sleep problem.
Whenever I put the computer to sleep, it shuts down(goes to sleep). When I press the power button to resume, it actually reboots. (June 2020)

I did a clean install of 2004. (I had an install of 1909, without this problem)

In July Sleep started working without me changing any settings. (no other bios settings, no deliberate changes to windows)

After the last round of Windows Updates... (2 weeks ago?) Sleep does not work anymore. I tried to uninstall, but not all updates wanted to be removed.
How can I troubleshoot this? The Power troubleshooter says nothing is wrong.

Can I find something about this in the logs? I've looked, but maybe I should look somewhere else?

Answer 1

Hi, I have run the Power troubleshooter again - no errors.

I then read the article you referenced. This was dealing with what happens when the lid of a laptop closes. I have a desktop. These settings are not there,

I then followed a few of his links to other articles he has written about power configuration.

I did notice that "Hibernation" is not available to me in my menu.
So I edited the registry to enable hibernation.
After that, still no hibernation option in the start menu.

I then remembered that there used to be a cmd-line command (powercfg -hibernation on/off). So I set that to on.

Low and behold - I can now put my computer to sleep, and when I push the power button... It actually wakes up.

I am going to test some more; and with a longer time in sleep (I tried now with one minute).

Also, thank you for the articles, very enlightning, I'm gonna read some more on your site.

Hello,

Please run Power troubleshooter from Settings app > Update & security > Troubleshoot. See if it helps you.
