oh, damn, i just saw this. i have the same dv9000. they really are victoms of heat from both the shitty graphics, and charging circuit. the beating on it will eventually kill power on the motherboard. give it a good flex on the body once in a while......i just upgraded mine with better graphics, hdmi, improved cooling, dual hd's etc...... for the warrenty one, i would have just poped the hard drive out real quick, via the hd door, go out to your car, start it up, and run as much juice as you can.lights, etc....hold the hard drive up to the alternator for a few seconds, and it's done. reinstall, and "click...click...click.......................click...click......" that's it. the winding field is alot stronger than a magnet, as far as wiping a hard drive.
