Thanks for replying @2informaticos . No, I don't have PP3V3_SUS.

Hi! I have this PCB without traces of humidity but it does't turn on: - PP5V_SUS: 0V (not short) Greetings and thanks.

The voltages that I have posted are with the board powered by power supply and BY3200.

PPBUS_G3H not stable = 8.40V goes up to 10.30V and goes back down.

Hello! The Macbook comes wet in several areas and after analyzing the power-up sequence, it has the following voltages (I'm omitting some that are present): PP1V8_SLPS2R 0-1.8 VARIES PP1V8_AWAKE - 0-1.8 VARIES PP3V3_AWAKE - 0-3.3 VARIES PMU_PVDDMAIN_EN - 0V PP3V_G3H_RTC - 0-3V VARIES P5VG3S_EN...

yes, I also changed it just in case and it gives 1.1V; It also doesn't turn on with SMC bypass.

Hi! I have a problem with an 820-2330 that doesn't turn on: it has these voltages. PPBUS_G3H = 12.66 PP3V42_G3H = 3.41 PP5V_S3 = 0V PP3V3_S5 = 3.3 Thanks.

I have disabled the GPU and now it starts OK: GPU is damaged?

Yes, I tried with an original battery but it does the same thing. Instead of resoldering it, I changed it. I haven't tried disabling the gpu.

The customer tried to change the battery and after that, it stays at the logo. I have tried to boot from an external hard drive/pendrive and they never fully load. Any suggestion?

Wow, I have no words: R7900 was burned out. Thank you very much @2informaticos and if it's not too much to ask, could you explain the relationship between the short circuit (PP3V3_G3H_T) and the R7900?

Hi, The PCB had short on C4910 (PP3V3_G3H_T), I replaced with a C of equal value but it still won't turn on. Following the thread https://boards.rossmanngroup.com/threads/820-01041-stuck-at-5v.55802/, I put the voltages: PPBUS_G3H: 12.31V "U7800 SYM 1 of 4: PP3V3_G3H_SOCPMU = 0.6V...

I finally changed the SMC and the battery issues were fixed. It can be marked as repaired and thank @2informaticos

Yes, it recognizes it after 1-2 minutes of logging in. With the new battery, I can turn on the macbook but still, it recognizes it after 1-2 minutes and even if I charge it, the percentage doesn't change (I look at the information about the remaining charge and after a few minutes, I check...

Newertech battery. Yes, I have an "old original" battery and this new one.

Yes, it's a new battery with 1 charge cycle. SMC_BC_ACOK = 0V (battery connected only).

Thanks to @2informaticos for the information: I have managed to get ppbus to be correct (12.58V) and to charge but, I still have problems: when turning on the macbook, the battery appears after 1-2 minutes of logging in (charger connected) and when I disconnect the charger, it keeps marking as...

I have changed it 3 times but it remains the same, it doesn't charge the battery and it gets hot (Q7130).

PPBUS_G3H = 19.20V.

I have injected V = 1V into PPDCIN_G3H_CHGR and R7021 / 2 was getting hot: I changed the resistors, changed Q7130 but it still doesn't charge the battery (R7021 / 2 no longer gets hot). With thermal camera, Q7130 heats up with charger and charger + battery.
