Well i may introduce myself here...

Im a computer enthusiast wayback early 2000, been repairing basic troubleshooting with my basic knowledge and skills
just recently post in this forum since i recently graduated from a laptop board level course... thinking that it will greatly enhance
my knowledge in repairing... but ive been a member of this badcap family many years back just didnt post anything since
my knowledge in troubleshooting is poor... and thinking that i will just waste masters repairmans and moderators time.. but recently im proud to be an active member...

good day sir... thank you for ur reply... this are the test i took...

adapter rating 65w 19.5v 3.33Amps

adapter voltages when not connected to the motherboard
3pins black= gnd
white=ad_id = 18.88v
red=positive = 19.71v

adapter voltages when connected to motherboard
ADP_id= 0.800v red= 19.71v
is ADP_id correct voltage?

REsistance between Adpter pin white and red not connected to motherboard
380.8koms
when connected to motherboard
31kohms

Resistance test ACP/ACN
Gnd to ACP/ACN =...

History of this laptop water damage... no power at first 19v CSR pin not present after replace first and 2nd mosfet.. 19v present... now its not turning on adapter present with battery not charging
but if battery only turns on... the corresponding voltages of the BQ24780s
