SMC_BC_ACOK @ U6901 is 1.3v but unstable.

U7000::14 == 1.3v and unstable too.

ppBUS_G3H == 12.58
PP3v3_S5 = 0.

Not looking at further rails till I get the One-Wire circuit fixed.

Powers on from charged battery?

 

[gcain]

Yes, it does. I missed that some how.

It even chimes, but no backlight (will sort that out later).

Corrosion on Q5310 or under SMC, pull up R5087?

 

[gcain]

Arg!
Plugged the board in to poke around and it booted straight up.
Works every time now...

I'll leave it till this afternoon and test again.
