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.
