Anyone ever found a long term solution to this problem? I got one broken for free, placed a shim under the gpu and used it for a couple of days. Now it's failing even with the shim.

It's really a design problem, there's no heat spreader for the radeon GPU nor fan. The note is structurally deficient, everytime you move it or simple use the palm rest the logic board flexes. That plus a buttload of heat from the GPU equals to broken solder joints.

We do the shim thing at our shop.
For a pair jobs, we use a C-clamp. :twisted:

I think I overdid the shim thingy on my first try, I stuck the largest coin here, 25 cents, under the gpu. Sure it applied lost of pressure on the pins but also flexed the logic board like crazy.

I always wanted the learn the heat gun reflow trick, looks now I'll have to. Maybe if I get it working in the end I'll cut a nice copper foil and place it over the GPU to help with the heat issue.
