"Replacing motherboard MacBook Pro 15" early 2011" için yanıtHello I had this problem, I had my mbp atended for it, and the Logic Board replaced . After the 90 day warranty period expired ... it started failing, and I am just cruising forums to see if I find solutions or similar problems. It seems pretty bad, because now I took the laptop to an authorized dealer and service... And the test doesn't show the problem..they see it happening, but the test.... I have a sad theory that Apple just made some $@$*!& replacement and made it so the test wouldn't make it in the programme again...I hope I can find something, or some way to get some money for this one to get the ridicusly expensive Mbps from last year.... Hate this.
