Slut automatisk computeren, når der klikkes på luk.

Nu ved jeg ikke hvilken PC du har, men er den ACPI kompatibel?

Se evt. Enhedshåndteringen

Et par muligheder:
- Installer nyeste BIOS - kan være en mulighed.
- Er XP opdateret med SP1a og alle hotfixes? (bør den alligevel altid være...)
- En driver hænger (ex. netkort, USB, ...)

Vedr. ACPI fandt jeg lige denne tråd, som beskriver problemet fint:

The most common poweroff problem occurs because Windows detects that the machine is APM (Advanced Power Management) compliant, but does not load the ACPI (Advanced Configuration Power Interface) compliant HAL. To use ACPI, you must have an ACPI compatible BIOS and have the features enabled. The fact that your box powers itself off in 98 implies that you have.

Go to the Control Panel and open Power Options. If there is an APM tab (many machines will not have this!) then click on it and enable Advanced Power Management Support.

Another fix which might work is to open the System icon in the Control Panel, go the Hardware tab and open the Device Manager. (Shortcut: Start -> Run -> devmgmt.msc) In the View menu, make sure Show hidden devices is enabled. Open the System Devices tree and look to see if any devices called APM/NT Legacy are disabled. If they are, try enabling.

Smider lige et svar, hvis du kunne bruge input.

Jeps. Det virkede, dog tror jeg kun det blev brugt til bærbar. Men hvis det virker er det fint nok :-)

Det har intet med bærbar/stationær at gøre... Det er to forskelle PM tekniker.
