Software is MS IntelliPoint Pro.
LEDs on keyboard toggle for CapsLock, F-Lock, ScrLock, and NumLock.
For reasons unknown, one or more LEDs spontaneously toggles on. When this happens
the keyboard stops working. Unplugging from the USB port fixes the problem. Rebooting
usually works too.
I have four computers at home. This desktop was built by me for infrequent use. The hardware
is like new, so I don't think the keyboard is defective. The keyboard and mouse are corded.
Maybe I'm stuck in the past, but I've seen too many failures with wireless devices.
I need a solution.
