Replying to Macbook pro trackpad and keyboard not working

So I was just cruising the NS casually, and then my mouse stopped working and the keyboard went dark. I was like the fuck? It had a 90% charge and its plugged in now but still won't work. I'm using an external mouse and keyboard right now to type this but I got my mac in september so I'm pretty pissed. I've restarted it several times and nothing happens. I have a 15" macbook pro btw. Anyone know whats wrong?

Whats happened:
keyboard is unresponsive and won't light up
trackpad is unresponsive
apple logo still lights up
sound still works
still charges
external mouse and keyboard both work

+k for help
