I took my MacBook Pro to a local Apple retailer today. It’s Main Logic Boards gets replaced, to fix the annoying whining noise it’s emitting. This is the third time my MBP is in repair. Back in March Apple didn’t have a solution for the whining and in June I got a new LCD panel, a new battery and a new power adapter. Oh and btw, the trackpad button is starting to malfunction too. I told them to have a look at it, but this has no priority. I need to have the book back tomorrow - I’m leaving for San Francisco on Thursday.
