Good afternoon. My client brought me a Mac A2251 EMC 3348 that he bought at a sale. The computer is completely iCloud-free, but it came with MDM installed. He has tried contacting the company that provides the MDM in every way possible, but they are unwilling to offer a solution. The device is:
Model A2251 EMC 3348. Serial Number: C02G54CZML85
Apple MacBook Pro Core i7 2.3, 13" 2020, 512 GB SSD, 16 GB RAM.
I've tried changing the serial number of the SoC ROM MX25U3235F, but it hasn't worked:
C02G54CZML84 only works up to Monterey.
C02G54CZML86 doesn't work (I... -
Hi everyone - first time poster on here looking to embark on my first repair! Thank you in advance for any help!
My Macbook only turns on when the charger is plugged in and only the trackpad and fans show signs of life. The display, caps lock light and touchbar do not turn on. There was previous liquid damage to the touchbar but after cleaning and drying the laptop was operational for a year without any issues. There doesn't seem to be any sign of liquid damage to the board, at present.
What I have done so far:
- All of the routine diagnostic methods including... -
Hey guys, just troubleshooting a MacBook Pro A2289 with the 820-01987 logic board.
No fan spin, no booting, device not getting detected by the Apple Configurator.
Did a few basic things, the board gets to 20V USB supply according to my USB tester, F7000 fuse seem to be ok and not blown.
Board draws about 0.5A for about 10 seconds, after that it goes down to 0V. Found an n channel FET (Q4830) in the backlight supply(?) that could to be blown (pictures below), not quite sure about that, but t assume that should not be relevant, because I was testing the board...08-23-2024, 06:26 PM -
I have an A2251 820-01949 which had a failed TPS62180.
I was fortunate enough to find the video on "Exploding USB-C" https://youtu.be/CAGnMR1aVuE?si=O1oYvAyNMeAr4dv4 what was shared here on the topic.
I was wondering if there are any cross compatible models that have been discovered?
We have an apple ID locked A2179 Mac AIR it's CD3217B2 has different lithography and looks slightly gray but I'm assuming it's the same chip in principal, but I am also aware that for some inexplicable reason mac flashes these chips firmware depending on their location on the board.... -
I am hoping to get some advice. I have a 2020 13" Macbook Pro - A2251 that wouldn't turn on. I have done lots of electronics repair in the past but never on Macbooks. I have had this laptop sitting around and I finally decided to take a look at it and see if I could spring some life into it.
First, it wouldn't boot up at all. I did a DFU restore and managed to get it to power on. Did a full restore but the battery was dead and wouldn't charge. I put in a new battery in it but now it won't boot up when the new battery is connected. I ordered a second new battery just in case,...
