Pulling out the HDD and booting up any other OS? I'd try the current Knoppix or other Live CD/DVD for a test. This is one of your tech's best secrets. Noted a long time ago at http://tips.oncomputers.info/archives2004/0401/2004-Jan-11.htm

I own an Asus Q301LA laptop, and am having some trouble with the screen. When turned on, the screen shows the Asus logo, then the screen turns dark blue, almost black, and doesn't do anything else. The cursor shows up when the trackpad is touched, but that is all that will happen. Also, the battery light never comes on, even when it is plugged in. Their tech support gave me the equivalent of "I dunno, turn it off and turn it on again," so any help here would be much appreciated.
