Hi to everyone!

I have here a 820-2915-B board that after connecting to a defective charger (power cord was damaged and shorted) stopped charging battery.
Logic board works perfectly if battery is charged, and i can see green light (no dim, full bright).
I've already changed magsafe connector with no effects.

Where you suggest to start?

thanks!

is battery recogniced on OS???? If yes, check R7051-R7052 or resistance between pins 7-18 from U7000, if it is not detected check voltage on pins 4 and 6 from J6950 it should be about 3.4V..... Report values.....
