I'm trying to trouble shoot this 13" MBP, all the power rails appear to be present.
I see the power supply deliver ~0.58A on boot up then settles to about 0.38A. No boot chime, no screen. All the test voltages appear to be there; however, the PPVCCCPU_S0G voltages never drop fully to 0.6V I'm seeing ~0.83V and ~0.71V on the cpu supply inductors.
Anybody have any idea if this is indicative of a cpu failure or if there's something I should check.
There doesn't appear to be any water damage or corrosion anywhere.
Thanks.
