Dell Inspiron 1520 shuts down when power supply is disconnected, but battery shows it has a charge
I have an extended life battery purchased from Dell that has seldom been used. When the battery charge indicator button on the battery is pressed, it shows 5 green LEDs. If held for 3+ seconds, all lights go out. As I understand it, this means the battery is charged and is in good repair.
When I unplug the power supply, the PC immediately shuts down as if there were no battery installed. What can I do to troubleshoot this and/or make the battery work?

First check to see if the BIOS identifies the battery - F2 at powerup. Also check to make sure the contacts on the battery and mainboard are clean and not bent.
