    Serial number in the battery compartment is CNU409B9PD Product D0M57UC#ABA Warranty 3y3y0y

    Hp's support returns nothing for the serial number, but part surfer does. Raw display panel part number is 686047-001, but no specs. So I google that and find a 3rd party site listing it as 1600x900. Whew! Why can't HP just tell people what ALL the specs are?

    Anyway, it's dead. Symptoms are; three buttons below right side of display all light, stay lit when pressed. WiFi, power and charge lights on front are on. LED on scroll/num lock blinks for a bit. Absolutely nothing on the display, no backlight. The pop out keyboard lamp at the top of the display doesn't turn on. It does shut down by holding the power button.

    Fan is running full blast with warm exhaust so something in there is running.

    It's a nice looking laptop with 320gig, 4gig, DVD burner, 1600x900 display, USB 3.0, webcam, SDcard, ExpressCard, SmartCard, fingerprint reader, DisplayPort. It's also the easiest to open for service I've ever seen in a laptop. Just push one slide and the bottom cover comes off, no screws.

    LED blinks three times, repeats five times. Found a troubleshooting chart. Says 3 blinks is RAM. Popped out one of the two sticks and it's no longer a dead laptop. :)
    Hurrah! A cheap fix!
