Hi all, There are some issue with my keyboard, here is the symptom. The computer is a Intel NUC, there is a wireless keyboard and a wireless mouse, both are Logitech the one with small wireless adapter connect to the USB port on the NUC. Only the wireless keyboard disconnect intermittently(the wireless mouse is fine), reboot the computer can solve the issue. I replace the wireless keyboard with a Logitech Bluetooth keyboard, however, the same issue occurred. I have to reboot the NUC, sometime I have to remove the Bluetooth keyboard from the computer and add it again in Control Panel . I plug a wired keyboard to the NUC, it work properly when the issue occur to the wireless and Bluetooth keyboard.
