need some help on apple 820-2936-b motherboard

HI,
I get some funny thing on the apple 820-2936b motherboard.

1. When I plug in the power adapter, the laptop can turn on automatically, no need to press the power button.
2. In the log in screen, when I choose one of the account, It looks like some of the key already be pressing down and keep typing. Pretty sure that only 1/3 keyboard is working. (123qweasd...)

How do I get start to check the motherboard?
How to test the keyboard to make sure it is working or not ?

Is there a easy way to let me turn on the laptop without connect to the keyboard?

thanks.

Hi
Thats Normal if keyboard is bad or if no keyboard is attached ...external keyboard work good? Also inspect board any liquid damage signs on board by connector? ..is also a good place to start.
