Powers off 20 minutes after turn on if no mouse activity.

by Beachhome2 / October 6, 2010 2:19 AM PDT

The computer is a Dell B110 running XP home edition. When it is powered up the normal desk top displays OK. If I do not do anything after about 20 minutes the computer powers down.

On the Power Options panel the only Power Scheme shown is Minimal Power Management and all times are listed as Never. There are no other Power Schemes available. They seem to have been deleted.

This is very annoying when I return to start using the computer and it is shut down.

Any suggestions?

Try the screensaver set to never and none too. Here's why. Many screensavers max out the CPU, the CPU thermal limit is hit and it shuts down.
Good luck,

Thanks Bob,

I am not using a screen saver. Also after I start using the computer, i.e. moving the mouse and accessing email etc, the computer runs for hours on end without any problems.
It just doesn't like to be ignored after powering up!

Turn off indexing too.

Google that if need be but the common issues are usually CPU heat related almost every time I encounter this one. Be sure to look in the EVENT VIEWER for clues.

Hi Bob,

'Had to leave for a moment, back now. Tried setting screen saver to none. Seems to have cured it! Thanks again. 'Just shows experience counts.

That's a clue.

If screensavers cause it, this is a sign that the CPU heatsink, heatsink compound and fan may need work.

HOWEVER. At this machine's age I suggest you leave it alone until a backup is done as well as you can live without it during repairs.
