I use the exact same settings on my old Win10 MSI laptop where I did not had that problem..........
And yes,it goes correctly to sleep mode and also wakes up correctly...except the fact that the screen is off
It's like you wake up the laptop,everything loads correctly but to also wake up the screen,it requires some input
I understand, But just because they are the same brand, it's still comparing apple to oranges. UEFI bios are different, 10 and 11 are different.
I had a customer just yesterday with a Dell laptop with sleep/wake issues she had never had before windows downloaded a cumulative for 23h2. The above solved her problem so we did not have to uninstall the cumulative to prove if it was her issue or not.
Your thread title says "
Screen stays off after wake
Then You said "I have to press a key or move the mouse to wake the screen(the laptop is awake but not the screen)"
Be glad that your screen will wake successfully. Small price to pay. The many reporting they can't get their screen back at all without a forced shutdown and reboot would gladly change places with you. Searching the web will get you all kinds of sleep/wake issues. Since I run 24h2 my feedback hub is for 24h2. There are many there. If you run 23h2, check your feedback hub. I will bet you see similar reports.
Other things to try in no particular order, ,each with varying severity, if you choose to pursue it:
update your graphics driver from MSI.
If problem started after an undate, uninstall the update.
reset uefi bios to default.
Update to latest bios.
See if it happens in clean boot to eliminate software conflict.
See if it happens in safe boot to eliminate flaky 3rd party drivers.
Run SFC (system file checker) to check for corrupt system files.
Run dism using restorehealth option.
Do a Repair install.
Do a clean install.
You are wanting a cut and dried solution for a problem which IMO is no real problem at all since when, in fact, you are able to wake both the computer
and the monitor successfully. When it comes to sleep/wake isssues there's no "one size fits all".
