    Macbook M1 820-02016 Keyboard -Trackpad stop working after a while

    Hi friends.
    This model has a very weird fault.
    Macbook Air M1 A2337 - 820-02016
    it works for a while and after a few minutes the TRACKPAD AND KEYBOARD stops working
    I already formatted, I already changed flex and trackpad. The error continues, I tried with another keyboard and the same error happens.
    works for a while and then stops working trackpad and keyboard
    (i rebooted and it works again, after a few minutes the failure returns)
    THE BOARD LOOKS VERY CLEAN and IMPECCABLE

    Thanks

    Check if it is overheating. Contact Apple for advice and post your updates here.

      Same problem. When computer goes to sleep via closing the lid usually, trackpad and keyboard dont work.
      Either in the OS or recovery environment, suggesting it was not software related.
      Reflowed the area that controls IPD_SPI_EN_CONN and just in case the lid sensor controller (same area)

      Now 4 days and no more problem

          A completely similar problem with the Mac, the keyboard and touchpad did not work when waking up from sleep.
          I soldered the motherboard and it works. Thank you​

            After the waiting time, the IPD_PWR_EN rail is lost, causing the error TRACKPAD AND KEYBOARD to stop working.
            Fix by borrowing the voltage of pin (1) CC240 connected to pin (2) RC870​

              yay it works, but when I connected to pin 2 on RC870 trackpad click doesn't work. so I check the schematic the click function also requires IPD_PWR_EN. so I decide to connecting pin (1) CC240 to pin (1) RC870 and now it works keyboard trackpad and also trackpad click.

              so my question is, is it safe bro hoang sonw ?

                last pic are these diode readings?

                have 0.5v where you have 1.8v drop

                    That's another error.

                      Yeah figured. Took pcb out measured again with sensor in and keyboard in and it's 1.8v

                      Still does not work.

                      But in my case it does not work permanently.

                        MacBook Pro M4 Pro - no keyboard / trackpad / lid sensor
                        by mitchw
                        Hello
                        I got this MacBook Pro M4 Pro to have a look at.
                        It was tiny bit liquid damaged, just the edge of the board got 1 small 10x10 mm area wet. I've seen much worse that still worked fine to be honest.
                        Since it was liquid damaged, warranty does not apply anymore.

                        Anyways it was checked at an local Apple Store and they discovered that it needs new trackpad, new top case, etc. Also it needed a new lid angle sensor which they replaced.
                        The main issue was that the screen remained black.

                        Anyways I cleaned the liquid damaged area, put the machine back...

                        [Macbook pro A1708] [Boot loop] [Trackpad ?]
                        by No Lan
                        Hey everyone,

                        Usually, I'm not the type to ask for help, but this time, I'm calling on your wisdom and expertise I've seen what this community can do, so I'm pretty sure you guys can help me out.

                        Here's the deal: I noticed my MacBook got stuck in a boot loop. After opening it up and doing some initial troubleshooting, I found that the boot loop stops only when the trackpad is unplugged.

                        Now, just so you know, the trackpad actually works — I tested it with another motherboard and it's all good. Same for the cable, no issues there. The problem is only...

                        Apple Macbook Air M1 A2337 Trackpad problem
                        by Skrndelj
                        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...

                        MacBook Air M2 A2681 no Trackpad
                        by rynr
                        Hello,
                        I have been following the posts in the forum for some time now and have learned a lot. I would first like to thank you for this and hope that it will continue for a long time.

                        I received the MacBook in DFU. The recovery always failed with error 1. After some search, I was able to find a defective inductor (LT202).
                        After replacing the component, I was able to successfully complete the DFU restore. Unfortunately, the trackpad and keyboard where still without function.

                        So i measured all voltages and diodereadings on the JT400 connector. ...

                        Hi,

                        I hope this is the correct place to post about this device. I originally posted regarding this on iFixit so see the details from that post below:

                        "I'm hoping someone can give their opinion on the symptoms I'm seeing before I spend any more time and put money into this. I got this MacBook from a customer and after looking at it they decided they didn't want it.

                        It doesn't turn on and there's no visual signs of life. I have tried resetting the NVRAM, SMC, power cycling, unplugging the battery, using the charger with the battery unplugged. Removed the...
