Windows 10 Black Screen After Idle
Let me preface this by saying the computer is set to never go to sleep.
Update: I found out that a friend of mine has an Acer laptop just like mine and they both have the same problem. It seems Acer added something to their system that might be causing this issue.
Recently I have started having an issue where the screen would go black after sitting idle for too long. The screen-off timer is set for 10 min. After the screen turns off it will not come back on. I can hear sounds when people send messages or when I get notifications but no matter what I do the screen stays black.
I have tried the shortcut to restart the GPU driver Windows key + Ctrl + Shift + B
and I can hear the ding but still, the screen stays black. I have removed and re-installed the GPU driver without success. I have even remoted into my computer from another computer, via ConnectWise Control, and the screen is black on there as well. I find this extra strange because it almost implies that it isn't a monitor problem and of course it implies that the computer isn't actually going to sleep. It's just that display is going black. Even without a screen connected I can normally remote into a system and see the desktop.
Edit: As a test, I set the screen to turn off after 1 min. It looks like the computer is auto-locking before the screen goes black and won't come back on. I can't interact with the lock screen in any way and then the computer goes black. I checked the screensaver settings to make sure "On resume, display login screen" wasn't turned on. I can confirm, no screen saver is set nor is that setting turned on.
If I turn off the screen-off feature by setting it to never this doesn't happen. If I lock my screen manually it will allow me to log back in as normal. If the system turns the screen off at any point, because of the screen settings inside the "Power & Sleep" settings it will auto-lock the screen, show the lock screen, go black and never let you turn the screen back on.
It would appear this is a BIOS-related issue on some Acer laptops. There is a BIOS update that fixes the issue.
This link is only for the Aspire A515-56 but anyone else experiencing this issue can probably look for their model number and see a BIOS update for fixing the black screen issue. https://www.acer.com/ac/en/US/content/support-product/8614?b=1&pn=NX.A1GAA.002
