    A2289 keyboard replacement

    Hi, Has anyone done a keyboard replacement on MacBook Pro 13" 2020 A2289? Can it be replaced separately? Is it tricky? How difficult is it? A1706 difficult or as simple as A1278? Thanks!

    MacBook Air 2018 A1932 restore error 1008F and external boot is locked

    Not yet but I was thinking about it and hoping that maybe there is another solution. For DFU restore do I need the same A1932 model or A1708 and A1707 will do too?

    820-00292 iMac 27-inch 2015 no light on diagnostics leds

    No. First time I injected it at J6900. Now I tried to inject it directly at 12V_G3H and I got green light on the first diagnostics led. I went poking around for more short and found another one on PP12V_S0 line. Tried to inject 12V there but it only takes 1V since its shorted to ground. Nothing...

    820-3662 WD, magsafe light, fan spin but no chime or image

    Sorry did not understand you. BIOS you mean U6100? That one I need to read with the flasher tool and flash it to another bios chip, right? I can not simply replace it from another board. CMS I have taken from the same board. Thanks!

    820-00292 iMac 27-inch 2015 no light on diagnostics leds

    Hi, Tried good working power supply - no light on any diagnostics LEDs. Inspected board for corrosion or explosions - nothing. Seems like there are no schematics for this board either. Any known issues with this board? Any idea what it can be? Thanks!
