Hello everyone
i have a strange problem here
i replace this laptop motherboard with new one
with only ac it works without problem
when laptop is on and then plug battery,laptop turns off
no turn on with only battery
when battery is pluged in and press power button current rise to 0.33A and back to 0.02
voltage on battery when its pluged is changed in cycle between 0 and 3V
i tried "different batteries" and "different motherboards"
all was same
i have 3 new motherboards with same problem

do you have any idea that is the problem?
tnx

Check PQ103.

it was ok
i have 3 different new motherboards and check with 2 batteries with same problem:|

i find something new
when i remove PR3 and PR4 , there is no loop anymore and board turns on with AC and battery pluged in
it doesn't turn on with battery only
but when AC and battery is pluged, laptop turns on and when unplug AC, it stay on! and use battery

what data on SMBus can stop turning on?

Hello,
I am in exactly same situation here.
I think the battery is somehow wrong.
Is there any progress at your side?
Thanks

Hello,
Same here.
Changed and reprogrammed the EC - same situation.
Tested the battery to another laptop - the battery is in very good shape and works properly.
Any ideas,please?

Update: i test my board on another laptop and it works without any problem!

my problem solved by replace KBC from dead motherbard
this is dump file from kbc that solved problem
