hi guys
i have a motherboard here with strange behavior
when only ac is pluged worked ok
when just battery is pluged also worked
when battery and ac is pluged and its off, it charging and binking charging LED every 5Sec

problem is when battery and ac is pluged in and turn it on
it turnes on but doesn't use Ac and battery is in use
status is plaged in and use 0.0A
when unplug battery it stay on and use AC and after repluging battery it switch to battery again
looks like it use AC just when is off!

i have no idea what is wrong here!
what about you?!

Check ADAPTER_ID on JDCIN1 and AC adapter.

ADAPTER_ID=0V
ADAPTER_ID_ON#=3.3V

when laptop is off and AC and battery is pluged it use 0.8A and charge battery
but when i press power switch current drop to 0.00 and use battery
if i unplug battery ,laptop stay on and switch to AC

Resistance to ADAPTER_ID relative to GND, with an AC adapter connected to the laptop without connecting the AC adapter to the mains?

i can't find that resistor in schematic!
only PD304 connect ADAPTER_ID to GND

can it be KBC Problem?

Plug AC adapter in JDCIN1. Not plug AC adapter in AC. Check resistance on pin 3 JDCIN1 to GND (pin 4,5 JDCIN1).

oh! my mistake
dc jack pinout was diffrent from old motherboard and new one

old pinout was + + - - id
new one is + + id - -

i change pinout in dcjack and its ok now
thank you for help
