    MacBook Pro M1 Pro Logic Board 820-02100 Mosfet where to purchase?

    My reference only: TT10141.

    Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right direction without have to purchase this entire allusive board. Already checked with Digikey, Mouser, Aliexpress, eBay. Any suggestions?

    Mosfet specs are as follows:

    Chip markings: DC21BJ 010D 030D

    Measurements: Length 3mm x Width 3mm x Height .5mm.

    Package type: ONSEMI

      Have you tried asking Rossmann?

          Will I have a bricked logic board after reflow of the GPU v-core U8900 chip on my Mid-2012 15" Retina Macbook pro?
          by korben_dallas
          Hi everyone! I'm trying to fix my black screen / failed U8900 GPU v-core on my Mid-2012 Macbook Pro 15" Retinaby doing a rework/reflow of the chip (once I determine that's the real issue; but it likely is).

          I've been disabling the GPU in NVRAM for a few years... but it's just time for a better solution.

          I'm new to soldering but the only feasible way to fix this issue is to do something myself.

          MY QUESTION:
          I've been seeing some people (on this forum mostly) run into issues with the logic board needing a serial number or it being deactivated (?)...

          M1 A2337 Macbook - No Display, likely due to logic board
          by ledbylight
          Hi all!
          This is my first post and also one of my first "deep dives" into electronic repair. I'm used to doing basic tasks with computers, like SSD/CPU replacement, thermal past re-application, etc. So here's the story...
          I have a MacBook Air M1 that I bought to repair (I know, I'm weird; though I'm a CompSci major and want to learn more , and it will not display anything on the internal display. I have verified that there's no backlight, as I booted the laptop and shined a flashlight on it and there's no display; it does completely boot up, and shows fine on an external...

          How do you test MOSFET in laptops ?
          by Jane
          I tried to use this method:

          Testing an N-channel MOSFET:

          Step 1: Discharge the Gate (turn off the MOSFET)
          Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
          Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

          Step 2: Charge the Gate (turn on the MOSFET)
          Now, place the red probe on the Gate (G) and the black probe on the          ...

          A2681 M2 MacBook Air Dead Logic Board
          by yuuki47
          Hello...

          My sister purchased an M2 MacBook Air a year and a half ago. While she was using it a week ago, it randomly shut off and no longer powers on. There are no signs of life and not even the MagSafe indicator LED lights up.

          We took it to Apple and they disconnected the battery and tried a bunch of stuff before they declared the logic board "brain dead" and quoted us about £567 to replace it. Typical of them...

          eBay replacements run about £367 with the Touch ID sensor included.

          I did consider to probe the logic board for shorts...

          MacBook Pro 2018 with Activation Lock
          by envym
          Hi everyone!

          I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

          I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...
