Acer Aspire 5742ZG-P612G50Mnkk
Motherboard:
NEW70 LA-5891P
Rev : 1.0
I have laptop that was in contact with liquid. It is working on battery only, if i plug in charger without battery nothing happens. I have check the charger it is ok (19V). I have check first 2 mosfet, on first i have on input 19V, on output 18.58V, second mosfet, input is 18.58V and on the output i have 8,3V. I have try replaceing second mosfet and problem was the same, so i shorted second and now i have 18.58V on main power rail, i have 3.3V rail and 5V rail, and it still works only on battery. I have try with 19V from power supply on output of second mosfet and it takes only 0.02A so i think i have no short on main power rail. I have no more ideas, and the sad part is that i have bordview and schematic...
HELP PLEASE
