Check if there is a voltage out of the power adapter.

Then mate it to your laptop and confirm the voltages on the logic board starting with the dcin power connector.

I notice the power switch wont turn on or it doesn't work .
is there a way to make it auto on while i plug my charger?

Does Anyone had an idea to auto startup a k50ij asus laptop ?when i plug my charger? Cause power button is not working.

Is that the only fault with the board?

Will check against the schematics once at the office.

See above. Locate and confirm if there is a pushbutton switch on your board to mimic the on/off function.

Measure the voltage to ground of pins 1 & 3 (either is ok as they are the same).

If you use tweezers or a piece of wire between pins 1 & 2 OR 3 & 4 (either pair is ok), this should act like your ON/OFF button.

That is, when the ON/OFF signal line is brought to a LOW level, you should be able to turn ON the logic board or OFF if it is ON.
