I dumped my mouse and keyboard that came with Idea Centre B500 ... using 14 year old wireless keyboard. It works. I spent hours on the phone with Lenovo support ... until it ran out. Got new mouse and keyboard, same problem. Asked for mouse and keyboard that work and was told that mouse and keyboard goes with that system! Yeah but it is not good for use intended! Oh well
