Hi, thx for helping me. i dont know how is first thats the reason why i looking ppbus first. There is no liquid damage. The resistance to ground on PP3V42 is 14.50 kOhms In diode mode have 345

Hi guys, I have a 820-00165 without PPBUS_G3H. I don’t know where start to fix. Seems like a short to ground but Im not sure. I let you see my measures. PPBUS_G3H : 0.50v @ F7140 (Its pretty curious but that measure is going down so slowly) PPDCIN_G3H_ISOL: 14.93v @ R7005 Pin 1...

Yeah, mee too.. im no planing spend time in this trash.

Nope, there are no shorted to ground.

I replace it and same thing. with and without the battery i plug the charger and i have green light, orange for a moment.. and again green light and stuck in green. dont charge the battery. what do u thing?

Duke, at pin 5 of Q7055 have some variables voltages.. i see 12,54v for 5 or 6 segs.. and decrease in 6 segs to 0,95v ... like: 12,54v (for 6 segs) and 7v, 5v, 4v, 2v, 1,5v 0,95v.. (6segs) And 12,54v again! When the battery is pluged in, have 12,55v stable. but stills having only green light...

So, you say this board is totally dead already?

Oh god.. so, any solution? replace the SMC? i never did replace any before.. too hard?

Yes duke, i did test with a new battery. so, you suggest to replace the Q7055?

ok, i will try replace isl6259 again.. see later and say u how im going

In osx says nothing.. only battery percentage and nothing when i plug the charger..

how can do a sms bypass? just for proof.. i dont have greenlight

im pretty sure this is not a liquid damage.

ehm, i use Brason, and the ultrasonic cleaner is a cheap one.. "VEVOR" ..

i have in diode mode SDA 609 SCL 612 .. this measures are at pins of u7000 resistance mode Open Line (O.L.)

Hi, i have a macbook pro here, my client trying to solve a wifi problem, burn the lvds conector and the lvds flex .. i reeplace thad but after replace, to remove the excess of flux i put the board in the ultrasonic and before that.. no turns on anymore. in any moment before the ultrasonic shows...

Hi, i have a macbook pro 820-2936 here.. the macbook power on normaly, with the charger, with battery and without battery. have green light. OSX recognizes the battery and the macbook can power on with a chaged battery. but the osx never seems the charged pluged and the battery never get...
