Absolutely worthless; reset my options for turning off display and sleep delay, but did nothing about powrprof.dll’s failure to sleep on command.

The solution I found is not to select the “Never” option under “When to turn off the display” in Power Options. Selecting 5 hours fixes the “will not sleep when lid is closed” bug.

Windows 8.1 Sleep Mode finally fixed! The two-step solution (for
me) was:
1.) Set the Windows screen saver to require me to enter password to log back
in.
2.) Power Options configuration: set the desired number of minutes for PC to go
to sleep.
Prior to this, I set two devices to not allow them to wake up the PC: HID
compliant mouse, and the Keyboard. It still wouldn’t automatically sleep, but
steps 1 and 2 above seem to have gotten it right.

Sometimes sleep mode issues are hardware related. I recently had to replace my power supply for this very reason. It would hibernate every time I told it to sleep. For ATX power supplies, Pin 9 is the one that keeps a small amount of power going to the motherboard while it is “powered down” or “asleep”… this is what allows for the ability of the machine to wake-on-lan, wake up when you move the mouse/keyboard, etc. I replaced the old power supply this past weekend (yes, the get age and go bad over time, we just never think about them, out of sight out of mind) and sure enough all is as it should be now.
