This board has had a lot of work done previously. unknown history, no water damage. ppbusG3_Hot is 12.26v BIL wasn't working originally due to broken pin, swapped connector and it works now. U7000 - 20.22 ohms pins 27/28 3.05 ohms pins 17/18. Q7055 is not being turned on by the ISL, I've...

I get a 0.53 v diode mode reading on r5280 and r5281, so they're not shorted to ground. I get 12.56v on ppbus_g3h with the battery unplugged. Tried known good battery. 3.17 ohms between pins 17 and 18 on U7000 20.28 ohms between pins 27 and 28. when I connect the battery PPbus_G3h will read...

this is my personal machine. coffee was spilled on it about 18 months ago with no major corrosion. Just died on me today. I found that pp5_s5_LDO was missing and with a little more troublshooting found no PM-SLP-S4_L

Tried other Battery indicator light in a different case. R6961 is there and has continuity. I get 3.4v on pin 5 of J6955 whether it's open or closed. Does that mean the other battery indicator light board is bad as well?

Thinks look ok around the u7000 area. I'm measuring 15.67v on charger bgate line, Is that normal for this board? it's around 12.5 on a 3115 I have sitting here.

Going through the rails, everything above pp5v_s5_LDO is stable, PP5v_s5_LDO jumps a bit when the fan pulses, from 4.89vto 5v. Every voltage below that pulses. Everything appears to be trying to come on. Is there a standard way of attacking 1/4 fan spin?

Board reads 0.005 short to ground in diode mode 4.99 ohms in resistance mode. If I inject voltage, it draws a hair over 1 amp, but nothing gets hot. CPU gets warm. Any pointers?
