Did you try the command
# reboot
(as root)
if it also does not work then change your kernel command line /boot/grub/menu.lst if you use GRUB and add option:
reboot=b
and reboot the machine. After this newer reboots might be OK.
Such problems are generally specific to certain motherboards. Did you check in linux-laptop.net for a similar specification laptop?
All these reboot, halt, commands are for safety reasons run only by root.
If you have logged in as user "JOE" in KDE/gnome....automagically then you can reboot with KDE menu and select logout/reboot.
Now to mount:
If there is an entry in /etc/fstab then NORMAL users can mount and unmount.
Post your /etc/fstab and we will see whats the problem.
Quote:
Which security settings control which programs normal user can run (specifically the halt, reboot, mount and umount commands)? I've seen people suggest all sorts of interesting ways to get around this but I think there's got to be some security files somewhere which controls which commands a normal user can run.

Dont do this unless you are ready to deal it later.
