Really dumb question - can a keyboard wear out? [View all]

I'm currently on my chromebook (which I love, btw). My desktop is the computer connected to my printer. I went in to print something, and the keyboard appears dead. If I hit number lock, the little light doesn't come on. I tried using other usb ports, and still no go. I tried connecting it to the chromebook, and nada.

Is it possible the keyboard has died? If so, I'll just buy another keyboard.

I only replace computers when they're dead, so this one is quite old. I've forgotten when I got it. The computer seems fine, as far as I can tell, although I can't get onto it without putting in my PIN, but it turns off and on and seems ready to work.

Should I just try getting a new keyboard?
