It might be your BIOS not getting along with Ubuntu, that's what was wrong with my Compaq. Go on your model's support page and try several BIOS firmwares (even older ones), see if they fix the problem. For example, mine only works with release 1.3, and fails to sleep with release 1.5 (the latest one).
