====== While using the Laptop on Batteries and when there is no A/C power: ======

1. Turn off Wi-Fi and BlueTooth.

2. Don't play computer games, music or DVD movies - Multimedia activities drain laptop batteries.

3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. 
   * Use the notebook touchpad instead of an external mouse.

4. Adjust your screen brightness - Dimming your display saves battery power.

5. Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 5 minutes of inactivity.

6. Decrease or mute the Laptop Speaker Volume.

7. Turn off all scheduled tasks.

8. Turn off Auto-save features in Microsoft Office and other applications.

9. If your PC has a built-in wireless card, turn it off or disable it when not in use.

10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

11. Let the battery fully discharge once a month so that there is good flowing of battery juice.
