My guess is the battery as the laptop is working with the power pack but not the battery. Look at the size of your power adapter and make sure it has enough wattage. It could be a case of it has enough power to run the laptop but not enough power to charge the battery at the same time.
I assume you left the laptop turned off with the charger plugged in? If not try that. If for some reason the battery charges with the laptop off, assume your power supply is too small.
Go into the ThinkVantage utilities and look at the battery health screen. Odds are it'll come right up and tell you the battery is smoked.
That's the bad news. Good news is a brand new R51 battery will set you back $150 and give you many years of service.
