Hello.
Work in a school and recently a few of our HP 8300 Ultra-Slim PC's will not turn on in the mornings. At 6pm they will shutdown and 90% in the morning turn back on via manual power options. However some of the machines will be completely dead. No motherboard lights, Just nothing.
Only fix is to unplug power from PC and put it back in, then PC comes back to life no problems.
All PC's have the same BIOS settings as it's built from an image, I;ve tested the trouble PC's on other power supplies but same result.
If anyone has ideas as to what is causing this issue that would be great.
