Having a a1502 2015 model,820-4924.

got liquid spilled on q7310, replaced.

check ppbus_s5_HS_COMPUTING,shorted to ground. found that q7310 is bad, replaced, q7310 and q7311.

Everything looks ok, then connected to charger. ppbus_G3h normal around 12. ppbus_s5_HS_computing is present and close to PPBUS_G3H

pp3v3 s5 is present,3.3v. don't see any other obvious spilled area. really get stuck now, any advice would be apprecaited
