Could you help which sensor to check? I only found those 5 I mentioned above.

PP3V3_S0_LEFT = 0v PP3V3_S4SW_SNS = 0v EADC1_TBT_T_ISENSE 0v EADC1_PP5V_T139_ISENSE = 0v EADC1_TBT_X_ISENSE = 0v Are they supposed to be high when indicating fault?

PP3V0_S5_AVREF_SMC is solid 3V on C5021 and C5020

In smc bypass mode with charger and battery connected and turned on 20v coming in: SMC_BMON_ISENSE 0.003v SMC_DCIN_ISENSE 0.005v CHGR_AMON 0.052v CHGR_BMON 0.000v It was 0.05 but I wrote 0.5 before, my bad :/

that was a challenge to measure SMC_DCIN_VSENSE 2.65v,

following values with SMC bypass with battery and charger: CHGR_AMON 0.008v CHGR_BMON 0.001V SMC_DCIN_ISENSE 0V SMC_PBUS_VSENSE 2.2V

The charger cycles between trying to switch from 5v to 12v with battery. CHGR_A/BMON are 0v. I found something accidentally, 1. starting MacBook without battery ribbon with charger. 2. I turn on the laptop. 3. I connect the battery ribbon (while it's starting) and the battery reports the right...

The machine always boots with charger alone Does not boot with battery only Only boots with battery and charger in smc bypass mode

Any idea? can all the batteries be bad? or the board?

Just battery SMC bypass without charger does not work, Battery with charger (and battery ribbon) SMC bypass. It starts, errors out first 1-2x, then it boots normally but I cant see the battery show up anywhere but this can be because of the bypass. If I disconnect the charger the battery holds...

Yes I have tried with the used known battery that came glued in with a top case, and 2 ebay batteries. They all have the same problem. It only happens when I connect the ribbon so it might be a lithium security cutout?

The laptop boots with charger alone, it's usable. I can login etc But with battery it keep cycling between trying to go from 5v to 20v (my meter says it dies on 10v)

I get 12.7V on PPBUS_G3H without the battery

Replaced D6902, It made 20v work without battery, with battery it still power cycles :( I just want to remind you that I destroyed the pad under pin3 as mentioned in the first post, so I had to wire D6902 pin3 <-> pin1 c6906 D6902 pin3 <-> pin1 c6905 Measurements: D6902 pin1 20v pin2 12v...

ppvin_g3h_p3v3g3h still 3.6v diode mode to ground is 0.55v from all 3 pins of d6902 before change I will source and replace the d6902 BAT30CWFILM and report back

my bad R6920 is 0.3ohm and 5.2v on both sides

R6920 is 0.8ohm, both sides are identically 3.4v I get open circuit on ppvin_g3h_p3v3g3h, thats the part where I was soldering... I wonder if I blasted the 2.2UF 20% 35V X5R capacitors when soldering them

got the fake battery and a macbook top with a used old battery. before I had chance to test any of it I realized that the 20v is not kicking in without the battery anyways. ppvin_g3h_p3v3g3h is 3.6v u6903 enable is 4.5v SMC_RESET_L and BUF_SMC_RESET_L = 3.4V PP3V3_G3H_REG_R= 3.418 v...

I had the seller send me a free replacement. Anything more I can measure while I wait for it to arrive?

820-00281a. seller claimed the battery is OEM, but it seems to be chinese OEM, I will look if I can find something else.
