Since you removed the battery anyway, make sure that the contacts on the battery and the laptop are clean. Replace the battery and try charging it again. Try a deep charge. If the battery is in a bad state, you might be able to bring it back to life with a deep charge cycle. First, make sure it's complete discharged by running the laptop with the battery installed (and the AC adapter removed) until the laptop completely dies. Then charge the laptop overnight. If you try all of these troubleshooting steps and your battery is still not working properly, it's time to get a new battery.
