No, No liquid. PPBUS just shorted to ground again. Found short on Q7530. Replaced it and now back to fluctuating DCIN. Im afraid if I keep it plugged in this will just happen again. Should replace all the mosfets to be sure they arent the problem or maybe just Q7550, Q7510... since they are tied to Q7530?

Update - Replaced Mosfets

CPU VCORE .895
PPDCIN 16.71 (steady)
PP3V42 3.395
Short on PPBUS again. 1.066V
