I have an HP 2000-bf69WM laptop that originally shipped with Windows 8. I have since downgraded it to Windows 7 Ultimate x64 SP1.
I have installed all the drivers from HP's website for the laptop, even though they specified that they were for Windows 8, they installed and seem to be working without issue.
Everything seems to be working correctly, however whenever the computer enters sleep mode, it will not wake. The caps lock key blinks once, slowly, which according to this HP support article, that means "CPU not functional".
Hybrid Sleep is off, and I have the Compatibility Support Module (CSM) enabled in the BIOS.
The output of
powercfg -devicequery wake_armed is completely blank, so this means that no devices are currently capable of waking the computer from sleep.
In addition to this, none of the devices in the Device Manager have the "Power Management" tab like I believe they should.

Does anyone know why this could be? Possibly a driver issue? Any help would be appreciated. Thank you!
