Resetting the Logitech K810 bluetooth keyboard

The Logitech K810 has been my favorite keyboard for many years. I have one at home and one in the office. It allows to easily switch between 3 different devices. It has the same size and layout as most notebooks, is stylish, and a blast to type. But one day about a year ago something […]
