How to Remove the Memory Effect on a Laptop Battery
Laptop (laptop and cellphone image by .shock from

Laptop batteries that are continually charged and not allowed to fully discharged lose their ability to fully charge and will eventually fail. This condition is known as the memory effect. The laptop battery may charge to only 95 per cent at first instead of 100 per cent. The battery's charging ability will slowly decrease until a charge is no longer held. Remove your laptop battery's memory effect without taking out the battery or making any modifications to your laptop.

  2. 2

    Insert a music CD or a movie DVD into your laptop's CD/DVD player. The music or movie will start automatically.

    Use your laptop as you normally would until its battery dies. The music CD or movie DVD will help to discharge your laptop's battery.

  4. 4

    Plug in your laptop's battery charger once the computer's battery is dead. Let the battery fully charge before turning on the laptop. The memory effect is now removed from your laptop's battery.

  5. 5

    Repeat Steps 1 through 4 every two to three weeks to keep your laptop's battery from developing a memory effect again.

Tips and warnings

  • If your laptop's battery is a lithium-ion type, these batteries do not develop a memory effect. To see if you have a lithium-ion battery, remove the battery from your laptop and look for the wording "lithium-ion battery" or check your computer's manual.
