I've got a laptop, an I've been using it for about 2 or 3 years now. About a week ago my keyboard started getting button problems- the '.' symbol's button cover completely broke and fell off, while the other buttons near it only started doing that but I fixed them. I can still press the button, but it just doesn't feel right pressing a piece of rubber instead of a button. I'll soon post a picture and I'm searching for the least expensive fix for this. My laptop is an ACER ASPIRE 5536G. All help appreciated.
