My Naga V2 Pro turned itself off and is now completely unresponsive

My Naga was working fine 35 minutes ago, when i came back to my desk after 10 minutes the mouse had shut off and hasn’t responded to anything since. I have tried connecting straight to the pc, resetting it, and pairing it again but nothing seems to turn it on again. I’ve had the mouse for a year and have loved it. What should I do?
