This NG might not be the best source of help. Have you tried comp .
sys . hp . hardware ? Or a forum at hp.com?

Thank you, this is a good start, I will visit these two news groups and

Please do still list more news groups here if you can think of anymore.

With the lights on the computer, I would assume you mean the power on
light? If there is power, and I would be using the power adapter, it
could be several things. The first thing I would do however is to
remove the RAM and reinstall it after cleaning the gold contacts with a
pencil eraser. A poor contact to the RAM would provide the error you
describe. You might also attach the laptop to another monitor via the
video output connector. It could be your display is the failing part.

Knowing how old the computer was would also be helpful.

Most likely the nvida video BGA chip has pins which have broken away
from the motherboard. There are places in the U.S. that will do a
competent repair and mod for $125.00. Chuck

Sorta. It's not really Nvidia's fault. Any of the large BGA chips
have problems maintaining a connection to the PCB. The court
settlement which extended the manufacturers warranty for such design
screwups is long over.

The HP dv6 is not on the list of affected models, but is one that I've
seen in the shop crap out in the same manner. You'll find vendors on
ebay that will fix it. For example:

You can also try to fix it yourself with a hot air desoldering
station. It's not easy or reliable.

yes, it is a solder joint problem, by accident I turned on the motherboard without the heatsink and fan assembly, within about 10 seconds the motherboard booted up. I then re-installed the heatsink and fan back on, while still warm, the motherboard functioned perfect. Turned it off and let it cool down to room temp, then tried to power up, same fault, all lights on and no post. after further inspection and testing found the Graphics IC to be at fault, needs reball and reflow. Same problem as all the damn ATI Graphics cards with large heatsinks.
Thank you all that have helped, your support is greatly appreciated.
