hp g62 mainboard repair help

[WarDaddy]

Hello everyone, I have a hp g62 that won't boot and I'm suspecting that is the mainboard since a couple of times the external monito did turn but with artifacts. I came across some dude on youtube telling ppl to remove the coil next to the gpu to interrupt the mb from using it. Then I googled more and found this forum with competent people, therfore I'd like to ask you what I have to do on the motherboard in order to get it to work. I got some liquid flux and an analog soldering station with regulable temperature.

More info about the laptop:
hp g62-125sl
i3 350m
mainboard DA0AX1MB6F0 REV:F

Thanks for reading!

So, it does have a dedicated GPU?? If so, likely its bad as this series is heading towards more or less "end of life" as far as gpu is concerned. There are two ways-Either you replace the gpu chip or convert this mb from discrete to uma. Conversion of this mb is not easy and bit complicated. I have made a post with guidelines on conversion of this mb in this forum which might help you. I assume its agpu problem as you are getting artifacts even on external screen.

BTW, reflow the gpu chip with a lot of flux and see if gives proper display to be sure its gpu problem.

Yes the i3 350m has a integrated gpu, and in case you want to help me I more than happy to convert this to uma. I did get a heatgun from my neighboors, the model is a suh2000, it has an analog wheel to regulate the power and 2 modes, 50-450c or 90-600c. I'm guessing leaving it on lvl 1 with the wheel at half should be 250, probably gonna try to see how much time it takes to melt sodder ona piece of copper. What do you suggest?
