I'm using a compaq presario notebook, i have sucessfully install mandrake 9.1 together with Win xp. In windows, i don't need to push the power button to turn the computer off. but in Linux after loggin out I would end up with the message "Power Down". can i do something so that i down need to manually push the power button to turn it off? Thanks for your help.

This is because your computer has a APM (Advanced Power Management chip) on its motherboard. Linux can work with these quite easily, but since mine was setup by default and I'm at college (on a windows machine) at the moment I can't find the option. Try looking for power management somewhere in the system setup (mandrake control panel?)

If you are a command line user, try:

shutdown -h now

just for grins. It works on my box but I am using a Redhat PC so it may not help.

If your notebook uses acpi instead of apm, you'll have to enable acpi. Mandrake usually disables it because apm works better with Linux.

Um...Whats acpi and apm? I am not having a problem but would like to learn from this one.

They're different systems for power management. The acpi support in Linux isn't quite complete, so Mandrake tries to use apm, in the hopes of your system supporting it.
