Well Jannie, I am a famous computer recycler so if you are not into something super new and fast I may be able to help out. Sky, I am too cheap to buy canned air. I take my desk top apart and vacum and blow it, and this lap top is closed when not in use. It was the external keyboard with all of the lovely dog hair. The keyboard on the laptop it'self seems to be working now that I took it out and put it back. Haven't seen my baby girl since 6:00 a.m. How do the years go by?
