Re: Trouble with a Macbook Air A2179

.0016 and a continuous beep

When I got the Macbook it had water damage near the USB controller chips. I cleaned it all up and replaced some ugly looking components. The laptop still won't boot. The only rail I'm not getting, as far as I can tell, is PP5v_G3S. However its my understanding that doesn't come on until the T2 powers up.

Which I don't think it is because I'm not reading PPVDSCPU_AWAKE at the 1.06V that I believe it is supposed to be. I'm reading only about .7V. I'm also reading continuity to ground on that rail. According to the schematic Vout on that rail is 0.625-1.06V. So I'm not sure if this...
