Hello
Im playing with my honor here.... cant figure out this!!
Working fine a1286 (2011) macbook 820-2915-A....
I needed to test a keyboard from another (identical) macbook ..
The keyboard did not work at all, maybe was bad or incorrect version. no labels at all...so i dont know....
then, reinstalled everything back to the good macbook , but now does not power on from power button, only from a short to GND at R5016... rest is normal...
I spent day working on this and this is ridiculous,
measured continuity from pin5 keyboard connector and was interrupted in his way to the other side: R5710 pin2
so made a jumper and thought would be ok....but
Still not powering on , but 3.33v present at R5710 both sides!!
what is wrong?
the same laptop powers on well with another motherboard, so it is not a keyboard issue.
What else can I try? some pictures as reference and schematics provided.
thanks in advance
