Wondered if anyone would have any advice to give or other things to check whilst I'm at it?
This item Laplife 60W mg1 Power Adapter Charger for MacBook Pro. So I have 2 that are missing from the diagram, then 3 that are reading different values.Īre the 3 resistors that have wrong values linked at all you think? I’m apprehensive about purchasing the soldering equipment and resistors if there could be a greater problem here. WORKS WITH: MacBook Pro (13 inch, Mid 2012), MacBook Pro (13 inch, Late 2011), MacBook. R7011 - 1.3, should be 9.31K, it also has ground both sides so shows this is gone I think? If you want a charger thats just like the one that comes in the box, this is the one.Reading other forums it seems it could be a problem around the U7000 chip and the resistors for battery sensing etc.
USED 2011 MACBOOK PRO CHARGER MANUAL
I have a copy of the Apple service manual and also open board so I can find the relevant resistance values etc. I have swapped the DC board to see if that might be the problem. I purchased a 3rd battery to double check, the laptop ran fine from the battery but would not charge it.
I replaced the battery with a newer one as the stock one was near the end of its life and said service battery, I suspect the battery i purchased although claimed it was genuine OEM damaged the Logic board.
