The vast majority of laptops don't have a discrete video card, the video chip is soldered directly onto the mainboard. It might be possible for this to have the solder re-flowed, if the chip itself hasn't been damaged. DV4 is a series with many individual models - if you search HP support with the complete model number from the label on the laptop, you usually find HP has reasonable service information available.

This is a simple procedure but near impossible to do without the right equiptment. I repair a lot of DV series mother boards by removing the old chip and replacing it with a revised chip that has better solder and then place a copper shim between the chip and heatsink to help transfer heat away from the new chip to prevent this from happening. Check with local repair shops in your area (not geek squad) and see if they offer this service.

Thanks for that information!!! I will presume the same is true of the Pavilion Dv6 line...

I was contemplating doing an upgrade of my graphics chip (ATI Mobility Radeon 5650 HD) bc I could not run ANY 3D MMO's like SWTOR or Star Trek Online. Having some experience with hardware upgrades - upgrading/building desktops, & having done some tech support with servers, it was something I started to research to see if I could pull it off with a lot of patience.

The more I read, the more I began to suspect my problem was actually with software - not hardware. I found an older version of my ATI drivers on my hard drive which I re-installed. I also found an older version of the ATI Catalyst. (I think the Catalyst was the culprit strangely enough) Now the games run beautifully. I had my laptop set for automatic Windows upgrades. Guess I learned a rather odd lesson.
