Hi All,
I've got a Windows 7 desktop PC at home that won't automatically enter sleep mode.

I've had this problem for a little while now, and a while back disabled the Keyboard and Mouse sleep functions, but still the thing won't sleep.

It's not really a biggie during the week, as the PC will go on, then I'll shut it down each night, but over the weekends it tends to go on on a Friday night, then off on a Sunday night.

The only changes to the machine recently, was the addition of a WD external TB HDD, and I installed the monitoring\apps\software for that.

Is there an easy\simply\straightforward way to reset the sleep setting back to factory without doing a rebuild?
