Your computer has memory problems. 1st check video. If video is working, you'll see an error message. If not, you have a parity error in your memory. Check your memory. Reseat them and try rebooting your computer. If this doesn't do it, the memory chips maybe bad. First banks are the memory banks in w/c your cpu finds its 1st 64k of base memory. You'll need to consult your manual to see w/c bank is 1st.. If all of your memory tests good, you probably end up buying new motherboard.


One long beep and two short beeps indicates that the GPU chip is not working.
I have found that the GPU gum between the GPU and the heatsink is meant to fill about a 2mm gap, but the gum dries out and cracks. When this happens the chip overheats, and the BGA pins on the gpu loose there connection. If you leave the power on after the beeping and block the vents a bit, the GPU/CPU heat sink warms up enough to expand the solder on the BGA pins and make a connection and the laptop will run. But eventually the solder will fully fracture, and a ball may come off and then you are totally stuffed.
Fixing the heat sink does not fix the problem - its the cause of the problem though, so if you do get yours fixed, I would recommend opening it, scrapping off the blue gum, and inserting a 2mm peice of copper plate on-top of the GPU and using siler thermal paste to connect the GPU to the copper plate and then again on the other side to connect to the heatsink. But this won’t fix it if its already dead. (I tried it and I get the same long beep, two short beep).
To fix the problem you have to re-flow the solder on the BGA. This should be done as a last resort (after your laptop doesnt turn on any more even when you heat it up). You have to strip down laptop to the motherboard. Bake the motherboard in a fan forced over at 80 degrees celcius for at least 24 hours (to get rid of any moisture that might be in the chip or solder). Immediatly after you take it out of the over, you need a hot air gun capable of reaching about 300 degrees. Heat the entire GPU chip and its board (don’t worry - all components can take 300 degress celcius for solder-reflow and did when the board was made). Keep bumping the GPU chip very slightly with a small screw driver, it will eventually become loose. Don’t lift it up however. Just keep the heat on for a few seconds to let the solder reflow and make a connection with the balls underneath.
After that let it cool down and plug everything back in and it *Might* work. If not can you heat it up and try again.
HP should never have used a BGA chip for the GPU. Its rediculous considering how hot the chip gets. I think nvidia are partially at fault as well - the 7200 uses to much power to be a bga chip.

Vertical black bars screen


Try connecting an external monitor to the 15 VGA (video) plug on the laptop and see if it displays properly on the monitor. You may have to direct the video from the laptop to the monitor by holding down the blue <FN> (key next to the space bar) and then press down the <F8> key.
If the display on the external monitor is correct, then you either have a problem with the laptop's LED display screen or cable that connects the LED to system board. Here is a link for the service manual:
