    RAM upgrade MBA A1466 820-00165

    You maybe want to get in touch with Colin (dosdude1). He has a video on YT where he did the RAM expansion, and mentioned he had to modify EFI to enable booting.

    A1707 tcon board

    I bought an A1707 off of ebay (yeah, I know...). Draws 20V, 1-2 mA. Found one of the GPU mosfets to be short, killing the AMD GPU. Previous owner reported screen was working fine when the macbook turned off, now on another machine I have backlight but no image, the screen is reported in macOS...

    820-00165 PM_SLP_S4L missing

    Just to be completely sure this is a no-fix: Board won't power on, but takes ~ .17 A from the bench supply. PPBUS_G3H = 8.58v, PP3V42_G3H = 3.42V PM_SLP_S4L is low, so I followed the guide from OBData, all logic signals are as they should be. The I checked all rails from S5 state (also from...
