MacBook Pro Charger Problem

[kcecka]

So earlier today my Macbook Pro charger decided to completely stop working? I fiddled with it and it turned on again, but it turned off again about an hour ago. I have a feeling I need to just bring it in and get it looked at, but if anyone has any suggestions for fixing it, I would appreciate it. Details below:

-I've had it for about a year and a half and it's been pretty gently used. I usually use the extension, but I don't have the smaller one on me right now so I can't switch it out to see if that will work instead. (Knowing my luck, it probably would)
-Charger is not showing any light at all, even when plugged in. When I got it to work earlier, it would switch on and off from nothing to the orange light.
-I've already tried rebooting my computer as well as completely unplugging the magsafe adapter for a little while and then replugging it back in. Didn't help.

Once again, I realize I probably need to bring it in tomorrow, but I mostly just wanted to see if there were any other options available for me. Thanks!
