I have a Acer Aspire laptop which I bought over a year ago. There are a few keys on one side of my laptop that are not working. These keys are the Caps lock, Tab, Esc, 1(!) keys. These keys will sometimes work but then just stop working and sometimes start working again. I've seen someone post a question like this having the same problems with the same keys on the same laptop. Is there anyway to solve this problem?
