I have had a problem with my aspire R14 laptop since first getting it a month ago. When I press a key in a certain are of the keyboard the whole keyboard bounces up and down. The problems is most noticible on the 7,8,9,u,i,o keys and is less noticible on the keys around those keys. It is hard to type because those keys respond differently. If I press down on the laptop case above the keyboard all those keys respond just like the other keys. So I think the problem is that the keyboard and/or case are not secured well in that area. Does anyone else have this problem or know how to fix it?
