Only thing you can do is replace it.
Or the AC adapter / charger plug is bad.
If the AC adapter isn't putting out enough power, the battery will drain while you're using it.
What's the voltage/wattage/amperage of the adapter? If you have one, you can test the outputs of the adapter with a multimeter.
