DELL VOSTRO 1550

BATTERY NOT CHARGING ADAPTER WATTAGE CANT DETECT

M/B- DV15 HR

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

SO I AM GOING THOUGH SCHEMATICS FOR ADAPTER PS_ID VOLTAGE AND TRACK

FOUND 2.7 V IN DC JACK PS_ID PIN

CHECKED AND FOUND PS_ID EC VOLTAGE IS OK 3.3V PR3806

SO I AM CONFIRM MAY BE SOME RESISTOR OR TRACK BURN

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

NOW DELL 65W DETECT IN BIOS AND BATTERY ALSO CHARGED PROPERLY
NOW PROBLEM RESOVED AND BOARD WORKING FINE
