working on this liquid damaged 820-3115, after u.c. the board powered on but had no wifi, and left shift key not working, also io0r sensor reading above hight point.
i got the shift key issue taken care of by replacing the keyboard connector.
Io0R current sensor is reading 10.999 a -I did check the u5410 area all looks good
pin3 3.31v
pin4 12.55v
pin5 12.48v
pin6 3.31v
not sure if this would be a smc issue or something else.
Then no wifi has me mixed up also
After changing wifi card and cable, checking for crap inside the connector i noticed i wasn't getting voltage out of q3550 so i changed it after checking the resistors and caps, but still no voltage out and no short to ground. not sure if the Io0R problem is causing the no wifi issue. would it be possible to run 3.3v from one side of q3550 to the other to check if that still works temporarily?
any help would be great thanks.
