I need my computer active all the time to process files, so I never let it hibernate, but I do want my monitor to sleep when I’m not interacting with the thing. At some point over the last couple of months, I discovered I was no longer able to wake the monitor with my keyboard or mouse. Cycling the power quickly became annoying and probably didn’t do my data processing any favors. I checked every setting and tried every solution imaginable. The only thing that worked was choosing a different power plan.

I switched from the Balanced to the High Performance plan. I kept my basic sleep settings the same. Somewhere deep in the Advanced Settings, something must have done the trick. My guess is the issue involves some interaction with the Intel graphics driver used by my monitor, but I haven’t taken the time to investigate. I’m just happy changing power plans solved my problem.

Most sleep and hibernation problems can be fixed by doing the following:-

Open a command prompt as administrator.
At the command prompt, type powercfg.exe /hibernate off, and then press Enter.

Restart your system.
Now go back to command prompt (as admin).
At the command prompt, type powercfg.exe /hibernate on, and then press Enter. (that is a space between exe and /)

This should resolve the problem whereby a computer will not resume from sleep or hibernation.
