Hi guys, got this one in, working. Customer wanted to upgrade, checked the board and area around Q5060 was corroded. Told him it needs fixing but he said he needed it at night, so came back the next day, mac died. Luckily not in my hands . Anyway, I replaced Q5060 and Q5059 and resistors around it. Also replaced C4907 and R5250 beside SMC. Then I replaced R6101 and C6100 that looked corroded. For the rest all looks pretty OK. Now i have green and orange light with battery plugged in, but missing PP5V_S3, I do have PP3V3_S5. PPBus sits at 12.6v and I have 3.42v as well. Also there is a short in PP3V3_S0, I see its also going to the area i replaced IC, but all resistor I changed measure OK. Should i first focus on the 5V, or are these related?
