    A1708 820-00875 battery drain in stby after SSD replacement by original one

    the A1708 is famous for battery drain in stby if a non OEM Apple SSD is installed.

    Got this machine with a defective SSD, installed an adaptor + 2242 nvme for testing. Works fine, but battery drain in standby; normal behavior.

    I ordered a used, but exactly the same SSD (the same Apple part number) second hand (from a macbook with screen issues). Works fine, laptop lasts 10H on one battery charge.

    Put them in deepstandby, confirmed by the pmset logs, and drains his battery in less than a week. Better as with an adaptor + nvme, but not the 30 days it should last on.
    Battery is new.

    Could it be possible this ssd must be "paired" or something with the motherboard?

      macbook A1708 - BMU replacement
      by Prott
      Hello,
      just a quick sanity check question before I blow myself up.

      Is it ok to transplant a working BMU from a dead A1708 battery to a working battery with a dead (not recognized) BMU? Assuming I will be very careful not to short anything out while doing it.

      I am just worried the BMU retains some battery specific data that will either kill the new battery or make it behave like an old one (the amount of charging cycles, etc.).

      Thanks

      Macbook Air M2 A2681 Kernel panics after screen replacement
      by reformatt
      Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

      It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

      Unknown transformer : how to find a good replacement part ?
      by the_rem
      Hello guys,

      I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

      I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

      PS4 controller left stick potentiometer replacement issue
      by ezenia
      Hello,

      Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

      So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

      I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...
