Is my wireless keyboard dead?

Yesterday it was working 100% fine. Today I woke up to it not working at all after getting charged throughout the night.

The 2,4 ghz wireless dongle, if I insert it in the USB slots, it does nothing, keyboard isn't working. I tried it on another laptop, not working. The keyboard doesn't type, and RGB isn't working on it either.

I bought it about a year ago or maybe 1.5 years ago, it's been used ever since. Do you think it's dead?
