I'm having problems with my laptop keyboard - specifically, some keys don't work any more.
The problem started three months ago - just three months after I purchased this ASUS K42F - when the left Alt key got busted. I cannot forget that moment because I was editing something important in Photoshop that required the use of such key. I didn't bother to do something about it; I still have the right Alt key anyway.
I was surprised when two days ago, almost half of all the keys in random positions didn't work any more. I haven't spilled any liquids on the keyboard, and I know nobody else has either because I always put this laptop in a vault when I'm out (privacy is a problem here). I've tried everything, from scanning for viruses and spyware to using compressed air, but nothing has worked. I hope someone can help me with this before I'll be obliged to visit the seller whose location is very far from mine. I still have the one year warranty.
