The Dell laptop battery receives its charge through the AC adaptor, a portable power supply that connects to an electrical socket. If the battery is defective, however, it will fail to charge, and the Dell notebook won't power on without the AC adaptor plugged in. If the battery isn't working, perform a few troubleshooting steps to attempt to fix whatever is preventing the device from charging. Doing something as simple as cleaning the device with a dry cloth can fix the battery.

Turn off the notebook. Disconnect the AC adaptor. Close the lid and turn the notebook over on to its face.
Slide the battery release tab to eject the battery. Put on an antistatic wrist strap to protect the battery from electrostatic damage.
Pull the battery out of the Dell. Wipe the battery and the contacts on the inside of the battery compartment with a dry, antistatic cloth.
Return the battery to its compartment. You should hear a "click" when you push the battery down into the bay.
Connect the AC adaptor to the notebook. Confirm the connection between the AC adaptor and the power cable are secure.
Insert the AC adaptor cable into the power jack on the side of the Dell computer. Insert the power cable into a wall outlet. Plug an electrical device into the outlet beforehand to confirm that the outlet is transmitting power.
Check the indicator light on the front of the computer. If the power light is solid or blinking, the battery is charging.
Connect an alternate, compatible AC adaptor to the computer if the power light fails to come on. Contact Dell for a replacement battery if the battery fails to charge even after connecting another AC adaptor.
