Hi,
that problems might have the followings causes:
a) an update of Windows XP on a old windows (need a clean installation)
b) if the xp installation was clean and you don't install thirds
software/driver yet, so the problem may be in your BIOS (no ACPI compatible)
or is only APM or need an update.
For to know if your bios is APM: right click on
MyPC/Administration/hardware/Device managment/Equipment/and look: if you see
"PC Estándar APM" in the menu see/show hide devices/ make sure the element
"NT ATM/Legazy Interfaz mode" don't have a red X; if yes must set the device
in Property/be able
if not must update your bios
c) If the problem (as in your case) come suddenly there is a driver non
compatible : find the problematic driver by selection
Note: if XP able the APM in a clean install, that is because the BIOS is not
apm compatible with ACPI, here the solution is update the BIOS
