Machines switch off if idle

Some motherboards can shutdown the PC if CPU temps are too hot...

Yep that would be a winner with me. We have had a few and when you check the cpu temp in bios it was nearlly 100c after removing all the dust from case fans, cpu fan, power supply fan its back down to 30c ish. It would stay on for a while and then just turn off like there was a power cut no warning.

Power options?

I'm guessing this too....

I use EZ-GPO client to set the power options by Group Policy. We had trouble with machines going into standby and hibernation at different times - and if people had/hadn't logged in. (Windows manages power options really badly!)

Also students didn't know if they were off, the screen was blank or the computer was in standby. Now they know that if the screen is black, just wiggle the mouse - no need to press the power button!
