My Windows 10 screen timeout settings are always:
Screen:
On battery power turn off after 5 minutes.
When plugged in, turn off after 10 minutes.
Sleep:
On battery power, PC goes to sleep after Never.
When plugged in, PC goes to sleep after Never.
I keep setting these to 30 minutes/60 minutes/60 minutes/2 hours, but they don’t save. They stay for around an hour and then reset. How can I make these settings permanent?
Answer
There’s most likely some power management software which is struggling for this setting. Laptops often have this. A search for “power” in Start should reveal it.
You can either uninstall the software or attempt to set your desired settings from within the program.
