Laptop Power Source Problem

[Phoenix Fury Legdrop]

I've got a Dell Inspiron E1405, and when I went to go turn it on last night, I noticed that I wasn't getting any power from the power source, despite having everything plugged in properly. The computer's running on battery power and the cord isn't supplying it with any power to even charge. I have no clue what the problem is and am scared that the battery's going to die soon. Any suggestions?
