History: It had some minor issue on PP3V42 and then it was working good. Suddenly shut itself off, then was working day after and again shut off. Turn on, shut off. I found some solder balls around U3740, but they could be a result of previous technician work since I see that CPU, SMC and BIOS were reworked on. (CPU and SMC missing glue, BIOS probably replaced). However not looks burned on the board. It's actually pretty clean.
PP3V42, PPBUS, PP5V_S0, PP3V3_S0 present.
PPVCC_S0_CPU not present. Barely 0.008V.
DCPS shows around 105mA draw upon boot.
Seems like CPU is not being told to turn on.
