HP/Compaq :: DV9000broken GeForce Go6150

DV9420us, had been dropped, and as a result a couple keys got lost and it wouldn't turn on anymore. I take a quick look at the machine, lights up but no video and it kept on restarting. "It's gonna cost $50, and another $40 for a new keyboard if it works. It's got about 50% chances to be fixed, if it doesn't work you get your money back." Guy agrees, i leave with the money and the laptop.

I get back home and take it apart. I remove the mobo, remove the cooler and CPU from the mobo, wrap it in aluminum foil leaving only the northbridge/GPU (the 6150 is onboard) and southbridge uncovered, as to protect the other parts from excess heat. Preheated oven to 190C then put board in for 7 minutes. Took board out, let it cool.

In the meantime i was busy cleaning the cooler - serving as "thermal grease" for the CPU was a piece of TINFOIL glued onto the cooler. This is ridiculous, it's a 2.2GHz chip. On the GPU, there's this sh***y thermal pad. No wonder the solder broke even though the chip was epoxied to the board. I applied thermal grease to both CPU and GPU, the crap thermal pad will have to stay however, as i had nothing i could use as shims there.

Put everything back together, and voila, we get video. It still needs some minor work done (besides a new keyboard) such as replacing the touchpad cable as it works erratically, but it's running. Shown running Ubuntu as that's the only bootable disc i found around the house.
