Macbook Pro won't charge -- dim orange light on charger
I was playing a game on my MacBook Pro (2011 15" running 10.9.1) earlier, missed the low battery warnings, and ran the battery dry. The macbook shut off on me, and when I went to charge it, the charger blinks orange twice but then settles to a very dim orange. The battery level lights, when pressed, show one light blinking as if it's not plugged in at all. I left it plugged in a few hours ago to see if it just needed some time, but it's still just doing a quick bright orange blink and dropping to a dim orange without seemingly charging anything.
I've tried resetting the SMC or whatever a couple times, and nothing's changed.
Please help; the last thing I need right now is a 15" Apple brand paperweight where my laptop used to be.
MacBook Pro, OS X Mavericks (10.9.1)
