Is there any common problem with this board? https://postimg.org/image/oichgovhh/

This Sony work only with battery but doesnot work only with AC adapter and will not charge the battery. Docking board has BQ24725 and ACOK - 0V if I measure the board disconected from the main board.

any common problem with docking board?


I have had them fail but only by someone fucking them up. Normal failure mode is shorted caps on the main 19V rail on the motherboard. Of course ACOK should be high. Just replace the board.
