820-00165 - No power.

Green/orange light works as expected/

PP3v3_s5 = 3.3V
PP3v3_s4 = 100mV.

C7518 had some stuff around it, so I cleaned it off and replaced it.

The board is remarkably clean.

PM_SLP_S5 is missing too because I seem to be missing S4_PWD_EN.

The few I remember solving of these were under a thermal cam and it was something around U7501 that heated up for a quick moment when power was first plugged in and then cooled right back off. I feel dirty admitting to a thermal cam having solved this.

Don't have a thermal camera, but can't detect any heat around U7501. It's 35c here at the moment so hard to detect something warm.

R1300 is 3.3v
R1303 is 3.3v

PM_SLP_S4_L missing is a symptom of another issue right?

Q7130::8 gives me 0.64v
On a working board I get about 1.7 to 1.9

 

[gcain]

PM_G2_EN is present at 3.4

Resistance to ground on C1001::1 is 0Ohms.


Edit: I compare C1001 on a working board and it is 8Ohms.
