Solving Dell Laptop Battery Does Not Charge Problem
A laptop utilizes a battery for power when it is not plugged into an electrical outlet. Dell Inspiron laptops use rechargeable lithium  batteries. The laptop battery has a life expectancy of 12 to 24 months, depending on several factors, such as care and battery usage tips. If the battery is not holding a charge, it may be damaged or dead and need to be replaced. Prior to replacing the battery, you should troubleshoot it, just to be sure.
Attempt to fully charge the battery. Plug the power adapter into the laptop and allow the battery to charge overnight.
Turn the Dell Insprion laptop off. Unplug the laptop from the laptop power adapter.
Flip the laptop upside down so the battery is visible. The HP 484170-001 battery is located on the underside of the laptop.

Slide the battery lock switch and hold it in place. Lift the battery upward for removal. Once removed, release the battery lock switch.
Examine the laptop computer battery. Look for signs of damage to the battery. If you notice any damage, the battery must be replaced.
Clean the battery contacts. Dip a cotton swab in rubbing alcohol and clean the battery contacts and the contacts inside the battery bay to remove dust.
Check the battery charge. Press the “Status” button on the back side of the battery. It has five lights that will display how charged the Dell inspiron 1520 battery is. Five lit lights indicates a full charge, one lit light indicates a low charge and no lit lights indicates the battery has no charge.

Recalibrate the battery. Place the battery back in the laptop. It will just pop into place. Turn the computer on and allow the computer to run on battery power until the battery dies. Once the battery dies, plug the power adapter into the computer and allow the battery to fully charge again. Remove the battery and check the battery charge.
