  1. Re: 00165 - Trackpad works Keyboard doesn't

    Have you tried a fresh install OS from internet recovery? It's alt+cmd+R.
    Do it with an external keyboard, also PRAM reset.
    If not I would put a fresh bootrom image in the BIOS.

    Re: adapter_sense is 18.5v

    P7 marked TVS diode tends to die, there can be shorted ceramic caps, small coils can burn out, also 10K 20K resistors tend to break down. That is all. All parts are covered. :)

    Re: 820-00165 RAM upgrade (for fun)

    Overshoot:
    Maybe you can get it up to 16GB, because it is the same stuff as the 2015 Retina board, that handles 16GB as well. But the air uses 4pcs of RAM dices, the Retina 8 pcs. The A1398 uses...

    There is no 16GB air, would kill the market... :)
  15. Re: 820-00244 dead, no g3hot, no rtc

    Power IC tends to fail on these ones. The sticky gunk you saw on the edges is the thermal pad that transfers the logic board heat to the body.
  16. Re: A1534 Macbook Retina 12" compatible keyboards

    There are also differences in the hall effect sensors, one has 1 other has 2, not sure which year is which. It is the trackpad that decodes the keyboard matrix, so i'm sure if you get the right year...

    Hey all,

  20. Re: Retina Screen repairs - no pictures, funky screen, etc...

    Used to hassle with Air LCDs, they usually had bad controller joints or layer separation. Never repaired any.
    As Rick I repaired many retina LCDs with bad LVDS connector.

    Re: 820-00239 Strange PPBUS_G3H

    Look for short at the part that used to be 3.425V generator circuit in older boards, so D6902 area, think the problem will be there, used to have a similar board with similar problem.

    I need BIOS readout and the matching QR codes from wireless chip and Touch ID connector flex shield.
    No need to have working one, just like it came from factory together, so mod-free config.
  24. Re: LCD display comatibility on A1502 Retinas

    Early A1425 model LCDs have narrow camera connector, you can only use them on Late 2012-Early 2013.
    A1502 models late 2013 and 2014 use the same LCD, you cannot differ them but they are the same....
