Problem with Laptop keyboard

[Jural]

I dont really know whats going on but for some reason whenever I press the shift key to type a capital letter its fine when it is the first letter but when I place a full stop and then try and type another capital then it deletes the whole sentence. I need the laptop for Uni and having to use the other shift key beneath caps lock is just very unnatural and annoying. If anyone knows how to fix this I'd be grateful.

Anybody any ideas ?

Maybe the sensor pad underneath the key is worn out or broken. Dust it out and try again.
