I'm getting stuck on this board. It has:
• 3V42
• PPBUS_G3H
• PPVRTC_G3H
• PP5V_S5
• PP3V3_S5
• PP1V05_SUS
• PP3V3_SUS

Does not have:
• PP3V3_S3
• PP5V_S4.
• PM_SLP_S4_L

I've been getting through these missing SLP boards pretty smoothly lately but this one is getting me. Any help would be appreciated. And let me know if there's other information I left off that would be helpful.

I'm assuming you meant 5V_S4 but let me know if I'm wrong. 5V_S4 is completely dead. Stays at 0V.

The board was cleaned before I got it but from what I can tell, it definitely looks like a liquid spill up by the CPU, to the top and right of it. Beyond that, the board looks pretty decent.

I realize SLP issues are tricky enough when they're right in front of you, let alone across the globe, but do you have any other suggestions for this one?

Is the SMC in the "right" mode, check the SMC_TDI SMC_TDO etc stuff. you can have a green light and still get shit on PM_SLP_S4_L if the SMC is trolling you.

Not yet. This one got cycled to the back of the line. I'll be sure to update this thread though when I get back to it.
