laptop keyboard not working
the other day my laptop power light would switch on but turn off within a second. today i managed to get the laptop to stay on but with nothing coming on the screen. in the last couple of hours i've managed to get it up and running fine with the exception of the keyboard. none of the keys are sticking but random keys appear to work for a moment then stop again - generally keys which are close together, e.g. q, 1, e and a. the little light on one of the keys which lets you know wifi is on never comes on noweven though the internet is ok.
i've tried removing the battery and charger momentarily,and just in case it was water damaged i put the hairdryer over it.
having no luck and on-screen keyboard is driving me crazy! what can i do?
