So, I have a Macbook Pro mid-2012 13" i7 2.9GHz. I have downloaded the schematic and the boardview file. I bought this secondhand over a year ago; it is a nice little machine, it has a major dent next to the magsafe connector, and the bottom aluminium panel doesn't fit, because, near the corner where the IR sensor is (near the arrow keys), the 'unibody' was bent inwards. I straightened that up with a pair of pliers used for car repair.
It has been fine, but I got it out from a short rest (3 months?) today, and it says 'battery not charging' 'power source : power adapter'. It runs from battery, runs from power supply, but will not charge.
I have a number of other unibody MBPs, which I can use to recharge the battery to prevent total failure (e.g. if the battery gets too low), so this isn't too urgent. However, there is 'something wrong' with the charging system.
I have tried two chargers - both don't work, but they do on other MBPs. The magsafe connector has no light (green, orange, or otherwise) at any time. SMC reset makes no difference. Most concerningly, U7000 has a dab of white paint on it, and it appears that this area has had 'some work done' at some stage.
I am using this system to type this with no issues (battery at 52%, not charging, on power supply). I will be mindful to not drain the battery, and have backup 15 and 17 MBPs to charge the battery if needed manually.
I have a known-good 13" charge port (ordered when this laptop didn't seem to charge but then worked fine so I never fitted it...)
Am happy for advice / questions as to initial tests. I have SMD rework station (fair quality), will order microscope from this website soon, and can get reasonable motherboard photos in the interim!
I have done the 2009 MBP 17" repair on a dead MBP - (tantalum capacitor) - it worked fine, and it is a nice computer. The cap is on a set of trailing leads - but still works fine - so can do basic soldering at least!
Thank you!
