HP dv9700 with bad gpu -fix?

Forgive me if I have misplaced my post. I am new here and from what i see this forum looks as if the answer to most any computer question can be answered.
anyway as to my question.

I have an HP DV9700 laptop. The GPU began showing signs of the GPU failures from all the bad Nvidia chipset/configurations that went out. When the computer is cold and not run it works fine. After its been on a while it begins having its problems. The cooling fan assembly has been damaged. the copper tubing has turned black. So that obviously needs to be replaced. I would have HP take care of it but its out of warranty.

My question is How bad is the GPU. According to HP the problem with the GPU's in my model is that the solder used melts at a temperature lower than the operating temperature of the computer.

So i have access to the right equipment to re-solder that chip to the motherboard. So do any of you think that i might get away with re-soldering? or would removing the chip cause the chip to lose its bios? or do you think that the damage is already done. That the power fluxation would have caused the GPU to be corrupted?

 

Only one person that I've seen post here at NBR has ever replaced a GPU by the method you mentioned and he'd been a computer technician for years and it took him hours, so that's out of the question. (To hard Basket)

I have seen one other guy post here saying that after getting a quote from HP to replace his mobo because his GPU was fried/de-soldered, he decided to try and re-solder the GPU and it worked. I'd say if/when your GPU dies completely you wouldn't have much to lose to give it a go if you're up to it.

 

mmm. sounds promising. any more thoughts? When i say i have access to the right equipment, i mean that i have a electronics repair friend who does this sorta thing for a living. he even has the multi point solder/de-soldering tools.

as for now, the computer works. Im just afraid of turning it into a brick.

 

Hi eatumup, I have a dv9500t with a GPU problem, i've done a research and found, like you, that i have to chage the motherboard. I was thinking the same you did and i found your thread. Please i'll like to know if you did succeeded, i'm looking for the time to try this.

I apologize for my English, it's not my native language.

 

Who is this guy? I would like to know because i want to do the same thing.

 

Eatumup did you repair it ?
