I’m stuck, need some advice please. This board works fine on charger with no battery installed.
With a charged battery and no charger it also boots and works fine.
When battery is installed and you plug charger in, the icon says not charging the battery briefly then shows no charger connected, light flashes constantly until battery removed. Light then shows green then orange.
Replaced u7100
q7130
q7155
Changed a whole bunch of resistors around u7100 that were marginally out of spec and probably didn’t need changing.
pins 27/28 measure 20ohms
pins 17/18 measure 2.6ohms
voltage at pin 2,19 and 20 of u7100
tried new battery
ppvbat_g3h_conn pin 5 is 16.1v no battery connected. Is 7.4v with battery
r5422 and r5431 in spec
acok is 3.4v
Any advice appreciated.
