This particular machine has some issues with its PPBUS_G3Hot power rail - it should be 8.6v and it's actually measuring just over 1v. Here we take a look at the schematic, board view and find the problem, replace the faulty component and get the machine back up and running once more. Unfortunately I cannot share these documents or link you to them but a search on Google will return them without too much aggravation. Any part of these documents used within this video are intended to facilitate the repair of the faulty equipment shown and for no further purpose. Many thanks for watching and please remember to comment, rate and subscribe for more videos. I hope to have more Macbook videos up on a regular basis going forwards - fingers crossed as I do enjoy working on them.
