as the title said.
macbook came dead, after inspecting everything, j3501 is prohibitng board from turning on if attached.
i used my good logicboard on customer part, the part itself is good. so the problem is from the customer logicboard.
diode mode of j3501 :
3 0.300
4 0.400
5 0.300
6 0.465
8 0.410
9 0.326
10 0.670
11 0.325
12 0.670
14 0.667
15 o.l
17 o.l
21 0.642
22 o.l
23 0.630
27 0.346
green light will not appear if j3501 is attached, ppbus is 12.26 at the moment.
if j3501 is not attached, board straight on turn on and ppbus is 12.6v.
im guessing this is smc problme ?
