Asus / K55VM / R. 2.0 / No power from DC, Battery power was OK

[Khaloun]

Hello to all.
I only noticed this problem after my battery completely discharged.
The computer does not work with DC power and does not charge the battery.
The computer worked with the battery until it discharged.
As I understood it, the problem may be in a DC power MOSFET, which I think it is on the top side of the board.
I measured about 19V coming to one of the MOSFET DC and 3V out of it.
On the other MOSFET DC I measured 3V in and out and on the MOSFET Bat I also measured 3V in and out.

Can someone please help me and confirm the exact location of each MOSFET and what voltage should I find in each pin?
I really appreciate any help.
Thank you.

Try to locate the schematic first.

it is possibly the battery at fault
try without the battery .. p.s some dont like having no battery so wont be 100 percent test .
