when I got it, i had to replace u7000, Q7030 and Q7035 because it didn't get a green light and PPBUS was 0v

now I get a green light, and posts but the battery is not detected.
can run on battery once charger applied then remove the charger.

I also have replaced Q7080, Q7055, Q7085 and D7005 just in case.

diode mode on:
SCL = 0.500
SDA = 0.498


resistance between pin 17/18 and 27/28 from U7000
17/18 = 3.1 ohm
27/28 = 21 ohm



PPBUS_G3H = 12.21v on charger
PPBUS_G3H = 11.39v on batt

real charger.
tested with two known working batteries.



DEAD SMC?
