I've had my HP Pavilion DV9000 laptop for a year now, and apart from a persistent (and slightly annoying) overheating issue, I've been very pleased with this machine. Recently, however, the touch-sensitive media control strip along the top of the keyboard has begun to malfunction. The sound toggle and volume control sections of the backlit strip turn off, flicker, change color (red and blue) and otherwise stop working. To make things even worse (or more interesting) such errors like the light flicker seem to be tied in to my typing on the keyboard, especially around the wasd area (left and lower side). I'm figuring this to be some sort of shorting circuit or the like? It's odd... sometimes I can fix the error by randomly tapping along the left side keys. Now it seems to be stuck with the entire strip non-responsive, and both blue and red LEDs behind the sound toggle turned on. If anyone could suggest a solution? It's that or I'm debating just taking the laptop in for a repair run.
