That happened at new year's night, when I was playing games with friends. The keyboard just turned off, I've exited game and Razer Synapse asked for an update, I updated it and nothing happened, keyboard wasn't recognized. I reconnected it to another usb-ports, some times it gave a sound like device is connected and keyboard lighted up pale, some times not. Every time I reconnect the keyboard to computer, it heats up in the right part of it. Asking for advices.
