Hey there, I brought the products of Razer a few months ago, to be more specific: 1. Razer Mamba 2. Razer Ornata I had enjoyed the usage of both, but a mouse stopped work a few days ago. Just stopped. When connected to PC it not responding on clicks (buttons) and moves (sensor), but still, the light is working and laptop identifies the wireless receiver. Tried to google it around, but haven't found a solution. Could you please help me with?
