Why aren't my Macbook and battery communicating with each other?

My Macbook has stopped recognizing/charging the battery. Help.

Today, I noticed that every time I unplugged my Macbook from the AC adapter, it shut down instead of going into sleep mode. When I plugged it back in and restarted it, I noticed the following:
The light on the adapter is green.
The battery icon in the finder bar says 0% for about 3 seconds, and then has an X on it.
So the Macbook thinks it has no battery and the AC adapter thinks the battery is charged. The button on the bottom of the Macbook for checking battery shows no lights when I push it.
I found an Apple document that suggests reseating the battery (done) and shutting down, disconnecting from AC, removing the battery, holding down the power button for 5 seconds, reinserting the battery and AC and restarting. Neither works.
Thanks in advance for your help.
