Hello, I recently bought a keyboard with a modecom mc-7200 wireless mouse, the equipment has one transmitter (as I call it correctly) the mouse works without problems and the keyboard does not work again. After inserting the battery, the diodes light up after a while. The keyboard is connected to the laptop http://www.komputronik.pl/product/306479/hp-pavilion-gaming-15-ak073nw-p1s67ea-.HTML that mine has 16 frames, not 8. In the device manager in the keyboard tab everything it's ok. Yesterday I bought and installed Windows 10 pro. Maybe you know what is the reason for the keyboard not responding? And I will add that there were no drivers in the package.
