Hi guys,
So I found a guy in France, were I live, selling a quadro p4000 mxm card (I think a Dell one but not sure). He is selling it for parts and says he is not sure what the issue is as he used it on his desktop with a riser and it suddenly made his PC refuse to power on. He wants 45 euros for it but I'm pretty sure I can get it down to like 35/40 euros.
The idea is that I buy it, and attempt to repair it to try to put it in my precision m6700.
I know a good bit about laptop motherboard repairs, I have already bought dead motherboards in hopes of fixing them, and I have already witnessed an i7-4700hq surviving a high side mosfet short. I also have access to good quality tools : a good hot air gun + microscope.
I am assuming that there is a short on this quadro, either a capacitor or a mosfet (seing as his pc refuses to power on at all). I have read up of people just replacing mosfets on mxm cards, especially 980m's and that they started working again no problem even though the GPU die was exposed to 19v.
So for people who have attempted to repair mxm cards : in your opinion is it worth the risk, what is the average sucess rate ? What components give out more often? Vram, Dies, VRM, Capacitors ?
Also just thinking of it now, if it's a mosfet short, since the guy was using it in a desktop it was 12v and not 19v meaning higher chance that the gpu die survied ?
Anyways, hope someone has info on repairing these mxm GPUs.
Thanks
