Tried 2 differents battery, and 2 different power supply.

Tried reset smc

No luck

Always green light
Bolt symbol

But system says not charging

Any help? Thansk

What is exact PPBUS_G3H voltage, w/ and w/o battery connected?
Any history available?

Check diode mode to ground at SCL/SDA lines of battery bus.

11,54v with battery 12,57/8,3 in loop with power supply only, 12,57 stable with battery and power supply

i've discovered that i have orange light if i connect the machine and power off it

scl/sda 0,500

You must get steady 12.5V with charger alone.
Check resistance (ohm scale) between pins 17/18 & 27/28 of U7000.

17/18 30 ohm, 27/28 20ohm

found the problem: r7052 were 18 ohm and not 0.

made a jumper and now orange light....and (i think) charging: it says "calculating charging time)

You should get aprox 2-3 ohm between pins 17/18.
2.2 + 18 don't get 30; 12 ohm is also bad for R7051.
