Just wanted to tell, a new battery is working well. Both of my previous batteries were bad. So my machine is working completely fine now. Thanks for all of your help!

After - doing some reflow/cleaning around the SMC (not complete reballing) - one of the pins of my battery connector was bent a little bit, so restored it - doing PRAM / SMC reset the machine reliably recognises my new battery. My old battery is not recognized at all, but it was in a 'Replace...

I've measured it again SDA: 0.526 SCL: 0.528 which is round 0.4% difference, so it's below 1% R7086 CHGR_AGATE_DIV (+), PPDCIN_G3H (-): 307.2 k CHGR_AGATE_DIV (-), PPDCIN_G3H (+): 325.4 k R7085 CHGR_AGATE_DIV (+), CHGR_AGATE (-): 485.5 k CHGR_AGATE_DIV (-), CHGR_AGATE (+): 391.2 k 26/U7000...

I had a little time, so I've removed, cleaned and resoldered ISL6259, but it's still the same.

Check resistance to ground (diode mode, red probe to ground) for SCL/SDA lines of battery bus. -> it's 0.530 in diode mode Be sure to have good solders on ISL6259. -> because at the first a quick reflow fixed my PPBUS_G3H voltage, it can be still an issue. I'll remove the ISL6259, clean the...

5. ISL pin 9 - GND: 0.298V ISL pin 15 - GND: 0.042V (/w power supply + battery) R7080: 99.6k R7081: 61.7k R7085: 391.4k R7086: 306.9k

1. 820-3332-A is a logic board for MBP retina 2012 mid, 15", 2.3 Ghz, 8 GB RAM (first rMBP) So it's before 2013. I don't know when should it show an amber/orange light. 2. ISL 17, 18 pin, battery current sensing: 3.9 ohm ISL 27, 28 pin, pwr supply current sensing: 21.3 ohm by my...

PPBUS_G3H with charge w/o battery: 12.51V which is somewhat lower than the expected 12.80V, but I think it's acceptable.

Hi! I'm writing the whole story, may it contains additional valuable information. One day, my macbook pro just switched off while working on it. Nothing trivial helped. Fortunately I have a decent electronics lab at home. PPBUS_G3H was missing, because Q7035 continuously shorted it to...
