    2021 M1 MacBook Pro (A2442/820-02098-A) Stopped Charging on All Ports

    So my friends A2442 MacBook Pro stopped charging one day and hasn’t worked since. It wasn’t like an immediate shut off, like it worked until the battery died but now she can’t charge it so idk what to do with it.

    I don’t have an ammeter (yet it’s coming soon) so idk if it’s doing anything funky with current or voltage but I know it doesn’t charge on ANY of the ports.

    I took it down to the motherboard hoping to see an obviously bad component but everything looks good.

    I don’t have much experience with laptops, only consoles and controllers so this is way out of my depth but it’s our senior year of Uni and she reallly needs a laptop lmao.

    I'm suspecting that it's the ISL charging IC but I honestly have no idea where to begin with something like this.

    NOTE: I forgot to mention but if the fix involves replacing components or chips or something I am capable of that^^

      Usually it's a corroded USB-C charge port on these. They are easily damaged by non-genuine charger cables. The user will have trouble charging on one port, then start using the other and then both don't work. You will need to remove it from the chassis in order to inspect it.

          MacBook Pro M1 2021 A2442 Touch ID stopped working
          by Gigabit2
          I replaced the audio board in this laptop and everything is functioning except Touch ID which no longer works. Neither Touch ID is detected nor the button itself works, so it does not turn on or off the computer or sleep etc.

          How can I troubleshoot the cause?

          MacBook M1 Pro 14" 2021 A2442 (820-02098) — U2020 getting hot, board not powering on
          by slimmy182
          Hi everyone,

          I have a MacBook Pro M1 14” (board 820-02098) with a broken LCD panel (matrix damaged).
          The board does not power on — when connected to power it draws about 5.1 V / 0.474 A (~2.45 W) and stays at that level, with no fan spin or display activity.
          Using a thermal camera, I noticed that U2020 heats up to over 70 °C shortly after connecting power.
          According to the schematic, U2020 is a SN74AVC2T45RSWR (Texas Instruments) 2-bit bidirectional level shifter.
          There are no visible signs of liquid damage anywhere on the board.
          Given the broken LCD,...

          Macbook Pro 14 2021 - A2442 - 820-02098-A not turning on 5v fluctuation
          by Rickkap
          I would like some help with this MacBook if possible. It came in with not turning on and the Magsafe light was off. After inspecting the logicboard i cannot find any liquid damage and also no burnt or shorted components.
          took some measurement and i can see i have fluctuation on PP3V3_S2 and also PP5V_S2_MAIN amongst other rails. Using the thermal camera RC282 & RC283 were pulsing, but after removing these it was still the same.

          I then did some investigation into why the rails were pulsing and noticed that P5VS2_PWR_EN (comes from U8100) is also doing the same thing.....

          M1 MacBook Pro 2021 A2485 - No backlight display
          by rcanpolat
          Hi all,

          I recently got my hands on an M1 MacBook Pro (2021, A2485) that I suspect suffered some liquid damage. I have a hot air station and the basic tools to work on the board, but I’m new to SMD repair and would love some guidance before diving in.

          Here’s what I’ve observed so far:
          • When I power it on, I hear the MacBook chime and, with a flashlight, I can see the Apple logo on the screen. However, it never completes the boot and eventually powers off. My plan is to try to get the display fully working first, then tackle the boot issue.
          • I did some basic resistor
          ...

          Macbook Pro 14 2021 - A2442 - 820-02098-A - Internal display not turning on but MacOS working good
          by modtool
          Dear collegues,
          the owner of this machine brought it to me saying that suddenly one day the display didn't turn on anymore, he tought that all the machine was damaged but it turned out that the MacOS starts good and stays on, and that connecting it to an external display it works without problems.
          If you take a look into general settings, you can also see that the internal retina display is recognized as connected by the main board but for an unknown reason it doesn't turn it on.
          I've tried to put a bright light towards the screen but I can't see anything, any shadows or apple...
