BIOS Settings

by TheChas In reply to How to solve Desktop auto ...

The first place to look for power up issues is the BIOS settings.

Look at the Power Management section.

Disable ALL Wake On Events.
Wake on LAN
Wake on Ring
Wake on Keyboard.

Make sure that the state after power is restored is set to OFF.

If the system still powers up on it's own, the next things to check are the power switch and the motherboard.

Unplug the front panel power switch from the motherboard.

If the system stays off with the power switch unplugged, the problem is the power switch itself.

If the system still powers up, you either have a bad motherboard, or BIOS problems.

Try performing a CMOS reset.

This system is also old enough that the CMOS battery might be weak and is the cause of the problem.

look for scheduled tasks as well

by CG IT In reply to BIOS Settings

in addition, you might have a scheduled task to run which will wake up the computer. If you run Norton AV or Systemworks and have scheduled anything to automatically run, Norton will also wakeup the computer to complete the task. To check scheduled tasks, click start, navigate programs, accessories, system tools, schedule tasks.
