Many years ago I had a MacBook that developed a graphics fault. The fault turned out to be pretty common. For quite a long time Apple pushed back on any suggestions that it was a design flaw, but eventually relented and offered a programme of free repairs. I had my laptop repaired by Apple under the programme.
Now, many years later, I finally got round to taking the laptop apart. I thought you lot might enjoy what I found.
Is that an IKEA non-slip mat?
(I’m guessing used to shim the GPU against the laptop case to reduce the chances of a recurrence.)
