Ok so I got an 820-4924 that has a slightly corroded lcd connector and the microphone connector was burned. I have PP3V42 and PPBUS G3H is 12.56V but no green light. There is no corrosion by the SMC or ISL. Could there still be an SMC issue?
Reballed SMC and no change. I think I stated before that I do not get a green light but I do get a MagSafe light. I?m still getting PPBUS, PP3V42 and PP5V_S5. I?m missing the two ?X239? rails in the G3H list, But I think one has to do with trackpad not being plugged in. Still not getting PP5V_S4 either
"I think I stated before that I do not get a green light but I do get a MagSafe light"
Do you mean amber light present on the Magsafe?
That is fine, why do you want to get green light?
I was supposing you don't get light on Magsafe at all.
Magsafe should switch from green to amber very fast, even no battery connected.
