    macbook pro A1989 restart when sleep and A1707 restart when shutdown

    Hello all,

    I got macbook pro A1989 that has sleep wake failure..always restart when put in sleep mode or close the lid..if i shut down and close the lid there would be no problem at all.. already reinstall the mac os but still has the same problem even restore with DFU mode.

    and for macbook pro A1707, this one always restart when i try to shut down..always restart when put in sleep mode.

    can anyone help me? @piernov, @mon2 ?
    thanks before

    Has this macbook an original Apple SSD drive or it has another brand of NVMe SSD? If the latter, it could be related to standby or hibernationmode settings (that can be tweaked with pmset command).

        Check voltage level of PCIE_WAKE_L.

        Most likely this will be an open-drain pin and is active LOW to WAKE up the host CPU. Respectively, the line will be high impedance for the 'high' state which demands that R1452 be present.

        Check that R1452 is attached onto the PCIE_WAKE_L line.

        Also check on the voltage on TPAD_KBD_WAKE_L. Consider to remove the trackpad connector to the logic board and test again. You should be able to turn on the logic board with pushbutton @ RE030 (attached).

        There are numerous widgets on the logic board that can WAKE up the host. Search for and investigate each "WAKE_L" marked lines to confirm they are ok.

        In the schematic, see:

        TBT_WAKE_L -> QB201 mosfet (level shifter) -> TBT_WAKE_3V3_L --> voltage reading ?

        Suspecting that one of these WAKE_L marked lines is parked @ logic low.

        My bet is on the trackpad line. Faced numerous faults with the trackpads in recent repairs from small spills, etc.

            Hi i was checking the PCIE_WAKE_L for my A1707.
            I am getting 3.15V.

            Having this same issue of restart after sleep mode.

              Search for the keyword 'wake' inside the schematic for the logic board.

              Then measure the voltage to ground of each pin with this name.

              If there is a '_L' suffix, then the signal is active LOW. If the pin is LOW, the logic board will wake up.

              And vice versa if there is no suffix.

                Update !

                There was a problem with one of the rails. Turns out it was a BadCap. Removed it. Issue Resolved.

                Thanks a ton.

                  by leonemax81
                  Hi guys I have a Macbook a1707 with motherboard 820-00281, without liquid damage that behaves strangely, with the battery connected the Macbook does not turn on and the USBC meter stops at 5v in loop, when I disconnect the battery the Macbook turns on and works fine, I have already tried to replace the battery twice without success, as soon as I connect the black cable of the battery the Macbook does not turn on, it stops at 5v and in loop.

                  Macbook A1989 / 820-00850 Restart problem
                  by GfilipeZ
                  Hi,

                  I'm working on a A1989 820-00850 Logic Board.
                  The customer complained that the machine restarted randomly.
                  From the analysis I made to the Logic Board, I detected a small corrosion in the IC U7430.
                  Although the diode values are all correct, I replaced the IC with another one. But the machine kept the same problem.
                  However, I noticed that whenever I use the Heaven software, the machine restarts after a few seconds. That is, it is enough to have an increase in graphics processing for the machine to restart.

                  Has anyone had a situation...

                  MacBook Pro A1989 820-00850-A not powering on
                  by ErinV
                  Hey everyone!

                  I have a MacBook Pro A1989 with a 820-00850-A board that recently stopped working. I used it overnight to charge my phone, in the morning it didn't turn on, I assumed flat battery but now won't charge and doesn't start at all.

                  I have fully dissassembled it, when disconnected the battery reads at 0.012V. Even with the battery disconnected the laptop doesn't boot.

                  The diode voltages around all 4 CD3215's seem fine.

                  For all CD3215 (UB300, UB400, U3100 and U3200) I read just above 5V on PP20V_USBC_TA_VBUS, 3.3V on PP3V3UPC_TA_LDO, 1.8V...

                  Macbook Pro A1989 - No image, working fine with external monitor
                  by Madoy104
                  Hi everyone,


                  I have a MacBook Pro A1989 that was likely exposed to liquid. It doesn't display an image on the built-in screen, but the screen is backlit (you can't see the Apple logo or any other elements when held up to light). The laptop provides 20V and 1.5-2A, and it works fine when I use it with an external monitor. Currently, the connector for the display (J8500) is disconnected. I'm writing to ask for help in diagnosing the issue. I've heard that when the J8500 is exposed to liquid, the processor pin responsible for the display might short-circuit, and I'd like to know...

                  Apple MacBook A1707 No Audio/Sound
                  by tommy97
                  Hi,

                  I'm having an issue with an A1707 MacBook Proβ€”there's no audio output. Initially, the MacBook came in with a no-power problem, and I found a faulty U6400, which I've now replaced. The laptop now powers on, but there's still no sound.

                  I've also replaced U6300, but the problem persists.

                  Here are the current voltage readings:
                  • PPV18_S0: 1.8V
                  • R6402: 1V
                  • R6405: 1V
                  • R6403: 1V
                  • AUD_SPKRAMP_RESET_L: 1.3V
                  • PPBUS: 12.6V
