I received a 2013 Macbook Air A1466 820-3437-B motherboard with serial number C02L6GQ9FSV8 that came in WITHOUT a bios chip. I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD. I've flashed a ton of bios but still same problem. Windows installation works with this Macbook but never a mac installation. Unfortunately, since I didn't receive this macbook with a bios chip, I don't have the original bios. What can I do now?... -
Hello all,
I am repairing a Macbook A2337 and i have a problem
The Macbook is stuck in restore as someone before me tried a DFU restore and bricked the device, now i can't do a restore as AC2 throws error 1 which is related to the trackpad.
When i turn on the device i get the trackpad click for a few moments and then nothing, i tried 7 trackpads and 7 trackpad flats, i know all 7 are functioning okay, especially one as i use it for testing and DFU restore.
I inspected the whole board and everything seems fine.
Can anyone help me as i didn't fiddle with trackpad... -
Hi everyone,
I have a MacBook Air A2179 in my hands that had power problems (5V to the USB-C port intermittently).
After a first inspection I could see that the D3302 protection IC was burnt out, so I replaced it but the problem was not solved, it seems like intermittent 5v input.
I then replaced the two u3200s (CD3217B12ACE) and now I have stable 20 volts and the macbook has turned back on.
Unfortunately I have a further problem, it works very slowly and the fan runs at maximum and if I disconnect the charger it turns off, it's as if the battery was disconnected.

Hi, I have a mbp a1708 2017 that I am trying to fix.
(1.) It turns on fine on ac power when bms flex is unplugged.
(2.) I noticed when battery & charger is unplugged and reconnected, it turns on only after a few minutes but doesn't stay on battery power i.e. it turns off as soon as charger is unplugged and doesn't turn on until (2.) is repeated. During this time, health information and charging information are displayed and normal and battery charges but laptop turns off as soon as charger is disconnected.
I have reballed u7000, problem persists.

Hey guys, I need a little help here. I have a MacBook Pro A1708 820-00840 stuck @ 5V. Started off affecting just one port but now it's affecting both. Both CD3215 ics were replaced but the issue remains. One port does a loop and the other stays at a constant 5V. Both CD3215 have 3V incoming. I checked for PP3V3_G3H @ R3000, C3100 and C3108, R3001, C3200 and C3208. The weird thing is though that the ammeter shows the current draw (5V @ 0.5A) coming out from the port as opposed to it going in. Any ideas on helping me fix this?
