The initial idea about mine, before it died, was to upgrade it with a new SSD, RAM and OptiBay. Even thought about 15" (same mid 2012, same non-retina). I've actually thought of buying the same MacBook, but used. So if it is indeed a dead CPU, then will it be anyhow possible to repair it (I know that the CPU is soldered, that task is difficult and complex, but still)? And does it make sense to repair it at all? I understand that maybe it is time to move on and instead of spending money to repair the old MacBook I should buy a new one.Īnd if anybody knows some good places to repair a logic board (preferably somewhere around New York City) would be great. However, I will have to wait until Apple Stores are back to work again. Contacted Apple and they told me that the logic board might be replaced for free in case it was a manufacturing defect. Still want to show it to other repair organisations. Those who repaired the short circuit told me that it might be a dead CPU and offered me to replace the entire logic board. Short circuit was detected and repaired, still not working.
When I connect it to the charger, there is a dim green light on the MagSafe. It doesn't turn on and the battery indicator doesn't work. Your question implies you might be firm with powered devices, but not with microelectronics as the magsafe connector (who has a high chance of being faulty) has only a few caps and resistors, so.maybe you are not the right person to try this on your own, no offense.My MacBook Pro suddenly got broken, model A1278, mid 2012, 13", i7, bought in 2013.
Usually everything is Intel reference design_except_for_apple_own_stuff which you're handling here. Schematics aren't available except for a few older machines, even within the company. Please give attention to ESD - might do more damages only by touch. Your best bet would be a smc-reset first, if that doesn't help try to replace the magsafe connector (under the board). Everything is SMD/SMT on the boards, this translates to: too small to repair or measure by hand, except you're hardcore into microelectronics and have the equipment.įor this exact reason parts like MLB (main logic board) get replaced in Apple Stores instead of 'repaired', as a skilled worker with equipment would be more expensive than replacing modules altogether.
