Keyboard Malfunction - PLEASE HELP

So the other night I fell asleep listening to my itunes and woke up the next morning to a dead battery, big deal right? wrong! I plugged my charger into my laptop and let it recharge for about 20 minutes before i turned it back on. It took longer than usual to boot up, in fact it automatically started up in "safe boot" mode. After a while, it loaded to my desktop and to my dismay i realized 9 of my keys fail to work. The keys (a, q, 1, f1, f11, f12, fn, ctrl, and delete) worked that night before, but for some reason since then do not work. I have never spilt any form of liquid on my laptop so that is not the cause, and i do take good care of it. I have tried everything i know to fix this, but the only way i can get it to type those keys is using the keyboard viewer which gets very annoying after a while. If anybody has a suggestion, I am all ears. Thanks.
