Im looking for schuematics of kboard it looks like the keyboard port is shorted.

Instead of power key i use esc button to power it on. But its still not go forward and just turn off. So i remove it and short the last to pin and it turns on normally. 

I wonder what else should i do to find the problem. Theres no skema availble for it.

The AN515-54 model N18c3 has no schematic diagram for the keyboards, your problem could be related to the keyboard (which there are many different models and part #'s) or the plug, cable and even the touchpad (replacement OEM is either TOUCHPAD ASSY BLACK-ELANTECH part #: 56.Q5AN2.001 or TOUCHPAD ASSY BLACK-SYNAPTICS part #: 56.Q5AN2.002) that in the AN515054 can be replaced, so check all that out first.

Also and if the keyboard mobo port plug is damaged then you can inspect it and see if its pins are damaged or its connection pins are also damaged? As and if the port is damaged then your keyboard will not work at all. The problem that you are having must be with either the keyboard itself and not the port that the keyboard plugs into at the mobo or it could be the actual keyboard strip cable that connects to the mobo as its pins must be damaged. Otherwise its your keyboard so look at any reference numbers on the underside of the keyboard (it should be something like 6B.Q5AN2.xxx numbers) so that you can replace your keyboard with the correct new keyboard. Try that as keyboards are pretty cheap to buy and easy to replace.
