Can't see any pics attached... never mind that, if someone sat on your laptop it's probable it has caused a severe shortcut of different keys. Two simple things you could do:
1. Remove the laptop battery, keep it out for a while, say 24 hours
2. Remove the CMOS battery, keep it out for at least one minute or, why not, the same 24 hours
This might nullify your settings, although I'm not the least sure about it. Do check that no keys are stuck - go rumble tumble through the whole set, to see if they act normally... play piano with your keyboard.
