Is your battery being charged, even though the amber/green light doesn't light up on the adapter?
If so, it may just be a problem with the LED on the adapter. If not, then you may have to invest in a new adapter.

It may also be because there is a short in the cable. Look for any cuts in the insulation on the MagSafe cord. I've had to splice cables that had been damaged multiple times and they work fine after my repair. I wasn't about to spend $80 every time my dog thinks the cord is a chew toy.
