It's probably the kernel, and/or the specific support for your laptop
that's messing up.  Or the hardware is dead.  But first, I'd check for
kernel messages ('dmesg' output is where those end up) for anything
related to 'asus-laptop'.  After that, the best you can do is file a bug
on Launchpad and hope the Canonical kernel team looks at it.
