MacBook Air A1932 Keyboard Schematic 820-01294-A
Can anyone help with a schematic and board layout for the keyboard 820-01294-A in Macbook Air A1932 please? (for reference, mainboard is 820-01521-A)
Alternatively, I'd settle for confirming value of a resistor on the keyboard (red arrow in picture below)
Water damage keyboard, with corrosion visible on the noted resistor (picture was taken after cleaning). One pad under the resistor was corroded and resistor fell off while clearing the potting resin (or whatever it is Apple has coated the components in).
By chance I discovered that mainboard 820-02443 has a similar circuit 2x L16A (PCAL6416A) ICs, but they are on the mainboard rather than on the keyboard as in the A1932. Using the 820-02443 schematic and board view, my best guess is that the resistor is on the IOSP1_RESET_L line, which means its a 10K. But, my confidence is low, hence reaching out to you all for assistance.
Thank-you,
Paul.
