Hi everyone,

This is a brief recount of the way we fixed my macbook pro with my brother in law. The laptop had its GPU fail, first on the external monitor, then, after a couple of weeks completely, rendering the laptop useless. Using google we managed to take it apart, dismount the logic board that we then baked in the oven for 8min at 190 degrees Celsius. After applying the thermal paste and reassembly all seems to be working perfectly. Macbook Pro still heats up very fast and is very noisy but that was that case so far. I shall monitor this and let you know if anything new crops up but this is a very inexpensive way to solve a dire issue.

Best to all.

Glad you got it working, but I don't understand the purpose of the "bake". Are you saying there was moisture in the unit? Or was it something else?

The theory behind it is that it is not the GPU that fails but rather some of the solder points. By baking it you refresh all the points on the logic board slightly, thus repairing those affecting the GPU. Whether this theory is true or not the fact ramains that before my macbook was toast and after baking it is back to working order. Time will tell if it holds.

190° C = 374° F

From Wikipedia:

Alloys commonly used for electrical soldering are 60/40 Tin/lead (Sn/Pb) which melts at 188 °C (370 °F) and 63/37 Sn/Pb used principally in electrical/electronic work. The 63/37 is a eutectic alloy, which:
1. has the lowest melting point (183 °C or 361 °F) of all the tin/lead alloys; and
2. the melting point is truly a point — not a range.
