'Turn off hard disk after' greyed out + pc crashes when going to sleep

rudolph · 16 Jul 2019

I have a problem where I can't set custom time for hard disk to turn off. This problem occurs when APM is disabled and enabled, so it makes no difference.

sfc /scannow shows no errors, I also reset all default power plans through cmd.

Another problem I'm having and I think it might be related is that when I press power button the screen turns off, but everything else stays on, fans are working and disk is spinning. Around 10 minutes later computer is off and I have checked event viewer, it shows that crash has occurred ('unexpected shutdown' or something similar). So every time I return PC from sleep it turns on just like after shut down.

But sleep works properly when I run it from start menu.
This problem started in the past month, after recent W10 updates.

Please don't recommend I reset my computer (that is always the first answer on Microsoft Community forums...)

Shutting off the hard drives is not going to make any difference in trying to place them to sleep. Also Lenovo adds their own ACPI software and drivers to their Windows OEM installs, which can contribute to problems when trying to diagnose them.

Still having sleep problem. I've noticed after full restart I can do sleep and wake 1 time, if I do it again it goes into black screen mode and I have to force shut down with a button.
