Evelyn has a Lenovo computer and her keyboard is acting up when she types. Letters repeat when she types. How can she fix that? Leo says that keyboards are pretty cheap now, under $10. So it sounds like her keyboard is ready to be replaced. It's probably the easiest fix for a computer out there. Here is a Logitech Keyboard with a mouse.
Chumly in the chatroom says that this is a common problem with Logitech keyboards, where the membranes dry out and bust. So definitely time for a new one.
