I have an Inspiron 1505 and the battery is not working. No lights come on when I press the charge button which means it has life. I check the status on the PC and it says the battery is dead. The little battery sign on the keyboard is flashing red when plugged into the AC adapter.

I tried disconnecting the battery and cleaning the connections. I tried to disconnect the battery wire but I could not get the bottom of the laptop fully off.

Any suggestions?
