Thanks for the patience vali!, ok, so when I connect the charger I get 5v inmediatly, whenever it does the transition to 19.4v it goes to 1v and then starts to drop...

Hi again, I´ve got this board which was working, I first turned on and work on the computer fine, but when I left it and it whent to sleep I found the problem that was reported. I have 3 beeps as for memory, as it is beeping I measured PP1v35_s3_mem = 1.35v, so I just want to know if this model...

Well... the computer is not starting, and I am getting 12.30 at ppbus_g3h which I think is not a correct value. According to me I have to have a steady 12.6 ppbus_g3h in order for the computer to run properly... correct me if I am wrong. I already changed the ISL and no change... still getting...

Hi, have this board with a low ppbus_g3h, tried replacing the SMC but had no effect, still getting 12.3v any sugestions? pp3v42 = 3.42 ppbus_g3h =12.3v pp3v3_s5 = 3,3v pp5v_s5 = 5v replaced U5010, replaced R5000 and C5020 which where making SMC_RESET_L unstable, still can´t get ppbus_g3h to its...

R7020 = .500v (and loosing power...)

so, nothing to do further?

I mean I did that, but the board is having the same behavior that it used to have, it is at 19.5v .026A and nowhere to go from there... any advice?

i did...

Ok finally got U7410 and replaced it, no short on PPBUS_G3H but I connected it and it is consuming .350 A and when you first connect the usb c it will go up to .700A but have no image on screen

DIODE MODE Q3100 1,2,3,4 = .650 5,6 = .180 7,8 = .560 Q3200 1,2,3,4 = .650 5,6 = .180 7,8 = .560 QB300 1,2,3,4 = .650 5,6 = .180 7,8 = .560 QB400 1,2,3,4 = .650 5,6 = .180 7,8 = .560 yes all usb c where doing the same, I started removing capacitors on the line PPVBAT_G3H_CHGR_R and now it...

with .026A and no PP3v3_G3H D6902 PIN 1 = 1.4v PIN 2 = .224 Both pins slowly going down.... U6903 PIN 1 = .100V (going down) PIN 2 = .1.100 (going down) PIN 3 = 0 PIN 4 = 0 PIN 5 = 0 PIN 6 = 0 PIN 7 = 0 PIN 8 = 0 PIN 9 = 0 PIN 10= .080 Picture 1 = Connected the usb c after a couple hours that I...

I don´t have access to a 20A PSU nothing to do in that case?

0.1 ohm

I don´t have PP3V3_G3H, there is a weird thing, on D6902 at both pins I get low voltages going further down while powered on and with a .025A consumption. Another weird thing is that I replaced U7000 and while the board was still a little hot, it went to its normal .700A of consumption, I...

Hi, when I connect the board to the usb c it makes the transition from 5v to 19.4v but is only getting .026 A. Don´t know where to start on this models... please help!

This board was working fine, it had problems with the ram, I reflowed it and it worked fine for a couple months, now it came with a short on PP1V5_S3 and nowhere to be found I removed all the ram chips and can´t seem to find anyshort... don´t know where to look now...

No, on the third restart, the backlight goes on for a second (I saw that on the monitor apple) then it turns off... the computer does nothing...

Hi, this board is pretty clean, just a little bit of corrosion in some pads, F7140 was broken, checked for a short on both Pins, but there is no short to ground.i Replaced the fuse and the board is turning to .600A but it goes back to stand by, it does it 3 times. the 3rd time it goes down to...

I measured PM_SYSRST_L and it was 1.8v, so since that one comes directly from the SMC I decided to reball it and it is working perfectly now. Thank you 2informaticos!

Hi, got this liquid damaged board, cleaned, removed a short on PP3v3_s4 and made it work, but next day it won´t turn on. I have the following voltages: It gets to S0 state with a consumption around .360A and then goes goes to .033A. Where should I start looking ? Just checked and I got a pulse...
