I have a HP wireless keyboard and mouse (model KBIM according to the sticker on the back). The dongle’s plugged into my Lenovo E460 notebook (i7 processor), running Mate 18.04. The keyboard loses keystrokes regularly, and I have to go back and add in the characters that have been missed. Very annoying. I’ve changed the batteries, and re-paired the dongle.
Is it just a “really-cheap-keyboard” problem, or is there something I can tweak in the OS?
