Make sure all the internal power connectors with the battery are clean. Make sure the wall outlet is active (I've seen a guy try for days to charge his laptop only to not realize that outlet to be controlled by a light switch). Check the power cable for any damage. Try charging the battery with the laptop powered completely off.

Is it charging while it's turned off?
