HP Omen 45L hangs during sleep requiring a hard reset

[OmenUser7]

MY HP Omen 45L has sleep issues.  HP acknowledged sleep issues.

I changed to an always on state, but the PCI Express still has maximum power savings state.

I walk away from my computer and come back to a PC with the internal lights partially off.

Monitors off.

I try to wake with kb/mouse and it is in the same state.

Tap the power button and nothing.

I have to hold the power button for greater than 4 seconds to hard-shut down.

Then I can boot it fresh.

Opened an admin cmd prompt and ran powercfg /sleepstudy

%userprofile%\sleepstudy-report.html

Appears to be a firmware issue.  Anyone have a workaround to the issue?

Greetings @OmenUser7 

Welcome back to the Forum.

I had a similar problem with a Gigabyte MB. It took a long time to figure out what was causing the problem. Windows modules and all hardware drivers were up to date except for one driver. Continue reading this post to see the driver I could not update until a later point in time.

I finally backed up data and reinstalled a clean version of Windows. Then used the PC without any additional stuff installed. Sleep was working when running Windows clean.

Then installed stuff, one at a time, and checked the sleep function. 

The version of Gigabyte RGB software I was using was causing the sleep problem. I had to wait for months until Gigabyte released an updated version of the RGB software. Sleep now works using the latest version of the RGB software.

Not saying you have the specific problem I had. But finding the culprit can be very difficult and time consuming.

You could have an asymptomatic hardware problem or a hardware driver problem. Windows system files could be corrupted. Flakey power supplies can also cause this symptom.
