No keyboard = no startup ???

Hello everybody,
I experienced an accident with my laptop (TM4670) as it get some liquid on the keyboard during a party. So, first move was to switch it off, dry all i could and see the damage.
At fist, I had only problems with some types which doesn't work or some other continuously stucked.
Up to this point, I thought a consciensous cleaning should do the trick and eventually its replacement.

But by now, It do not even start up ! Depending on times it launches till bios screen appears, other times it makes three "beeps" or most of the time it just switch on (power light on, fan on, DVD player running) but nothing on the screen.

I hope this is only due to the keyboard mulfunctionment.

I'm about to change it myself, do you think it could be the only cause of all my troubles. (i.e can the keyboard problem
prevent my laptop to start up normally, at least till bios screen).

thanks for your help and experience return !
