MacBook Pro 4.1 logic board change
我的问题
It is the common problem with the 2007/2008 MacBook Pro graphic card. Mine is a 4.1 (French!) model 2.5ghz.
我的修理方法
I have already "repaired" it once by baking the logic board. It worked... for a while! About 2 months ... But since I had a new MacBook Pro retina for a replacement, I put my old (and beloved :-) ) Penryn early 2008 in a safe place for almost 2 years! And 2 weeks ago I decided to make it alive again!
I ordered a logic board on ifixit website. Mine is a 2.5ghz but the model was not available. I took then a 2.4ghz model (the differences are on the frequency, the memory or the gpu :256mb instead of 512 and on the L2 cache). I followed the tutorial of ifixit and everything went perfectly! (I've already disassembled/reassembled it 10 times!)
I just had to parameter the keyboard since it was a US model and mine is a French one. El Capitan installed since then.
So far so good :-)
我的建议
As I read on some threads, thermal paste is a crucial point. Take some time to clean correctly the cpu/gpu and put a good quality thermal paste (artic mx4 for me)
