Battery is charging well with 3.17AMP CURRENT CONSUMPTION shown by PSU

 

BATTERY CHARGING WAVEFORM

 

User complaint is laptop become  to hot while charging battery

multimeter test shows charging voltage 10.44V to 11.65V  while SHUNT voltage drop of 31mV-39mV reporting current drawn by battery is approx 3.6Amp

So decided to mod shunt value to reduce charging current as well board heating

 

CHANGE SHUNT R010 TO R015 NOW CHG 2.06 AMP AND BATTERY VOLTAGE 11.75V

 

Charging time increased but this mod works well as per user satisfaction too good.
