Customer said they returned from holiday and it was dead.

Green & Orange light behave as expected. I can hear a soft ticking when I connect power.

Only corrosion was on C3532 and C7518 was corroded off the board.

I get 40mV at R7547::1 & ::2.

PPBus = 8.59v
PP3v3_S5 is up and down like a yoyo.
PP5v_S5 is the same.

PP3v42 is 3.4v as expected from the light.

Going to replace U7501.

Solid power going in, and everything coming out of it is fluctuating.
