CHECKED WITH OTHER BATTERY AND DELL ORIGINAL 65/90W ADAPTER ALSO NOT DETECT THE WATTAGE

PREVIOUS ENGINEER ALREADY CHANGE THE I/O AND ALL AD/BAT MOSFET

CHECKED ONE BY ONE AND FOUND PR3807 IN BETWEEN PS_ID AND PSID_EC IS BURN

THIS IS 33OHM SO THAT I JUST JUMPER IT AND GETTING 3.3V IN PS_ID PIN NEAR DC JACK IN
