Charger Light keeps Blinking. (red green red green)

hi I just noticed this yesterday.
When my battery is fully charged, the light on the charger does not remain green. It will switch to red for a second and another second it goes to green again. It has been doing this for a whole day already. What's wrong with it?
I know the charger is still fine, because it doesn't blink when the battery isn't full and my laptop is still working okay.

thanks so much!

Macbook pro 17", Mac OS X (10.4.10)

check your battery and make sure it's not expanding and it is working ok- holding a charge and everything. I had this problem recently and had to replace the battery because of this problem and others with the battery.

Check your power adapter plug and port for any debris with may be preventing a tight connection or blocking the pins from extending fully.

Alternatively, it may be a problem with your SMC, which you can reset as described here.

If that does not do the trick, it's likely a faulty power adapter, and I'd recommend a call to AppleCare.

Hope this helps...
