HP dv9000 Video problem, semi-functional

post #1 of 3
Thread Starter 
Hello everyone,
So a guy that I do computer maintenance type stuff for has a HP Pavilion dv9000 that is not working. He purchased it from Best Buy and had a service plan with them, they told him that the motherboard was shot, and that HP doesn't support this model anymore so there is nothing they can do. This was quite awhile back at this point, but he eventually gave it to me hoping I could figure out how to get it working by purchasing a replacement motherboard (probably by purchasing a for-parts broken dv9000) and replacing it.
So now I have the laptop in my possession and started just doing some general troubleshooting to verify what the Best Buy employee said. So, it doesn't seem to be dead, and in fact I've actually gotten into Windows in both Safe mode and normal at this point. It seems to be a graphics problem. I have done some searches and I came up with another thread here and a video about re-soldering the GPU because it becomes so hot that it can lose connection. What I'm not sure is if that is for sure the fix I'll need to do. Right now, I actually can get video out of it but it acts... abnormal. It only works if I have an external monitor plugged in, if I don't the laptop monitor itself just stays blank when trying to start up. When I plug in an external monitor I can only get into Safe mode. At this point, based on Stop code and some other info I decided to uninstall the video drivers. When I re-booted I got into normal windows and the odd thing is that now video is displaying on both the external monitor and the laptop monitor. I tried a couple of things at this point, rebooting without the external monitor, re-installing graphics drivers, and just unplugging the external monitor while its running. In all of these situations it goes back to no display at all.
So basically, does this sound like it still fits the bill for the GPU re-solder fix, or is something else going on here?
Thanks,
Victor

Additional info about the machine:
Intel Centrino Duo, not sure of speed
nVidia 7000 series mobile GPU (I think its 7300 but I can't say for sure right now)
Running Windows Vista Ultimate 64

I can get the specifics on CPU, GPU, RAM etc if the information would be helpful, but I don't think that exact info would play a huge role in fixing this.

Ive dealt with these HP models a few times and the nVidia grpahics is the problem. HP sued nVidia over this( and i think nVidia counter sued HP) They turned their back on this problem for the consumer. Everything I read on the subject was to reflow the graphics. Which is hit or miss. Worst case strip it down and sell off the parts. I know the screen alone goes for about $80-$100 on ebay(done it) thumb.gif

Thanks for the input. Looks like you were right, it was the GPU but I was able to get it working using the reflow fix. Unfortunately I apparently didn't reconnect the speakers/sound device when I put it back together so I have to do it all again... which is way more time than it should be, but oh well.
Thanks again,
Victor
