Hi.

This machine was bought on eBay about a year ago. It's been ultra sonic dirtied with god knows what.
Old gray corroed solder all over.

5V / 3V3_S5 are 5V and 3V3
3V42 is 3V42
Orange / Green OK
PM_SLP_S5_L is low
ADAPTER_EN 3V3
DSW_PWRGD 3V4

I put a new SMC on there as the old one had crap under it.
PM_SYSRST is at 175mV

PPVRTC 3V3

Could be corrosion everywhere of course :( The common stuff first, U1900,U1950,J6100,U6100 traces and resistors. Check all rails for shorts. Check if 32kHz is coming from U1900 too.
