Power Conserving Battery Power To extend the time that a battery pack can run the notebook from a single charge, use the following battery conservation procedures and settings. Conserving Power as You Work To conserve battery power as you work: ■ Run the notebook on external power instead of a battery pack whenever possible. ■ Prevent devices you are not using from drawing power from the notebook. For example: ❏ Turn off wireless and local area network (LAN) connections (select models only) and close modem applications. ❏ Disconnect from the notebook any external devices that are not plugged into an external power source. ❏ Stop, disable, or remove an inserted ◆ PC Card. ◆ Digital memory card (select models only). ◆ ExpressCard (select models only). ❏ Turn off a device connected to the S-Video-out jack. ■ Use optional, externally powered speakers instead of the internal speakers whenever possible. When you use the internal speakers, minimize system volume. Volume can be adjusted with the volume buttons. ■ Minimize screen brightness. To decrease screen brightness, press the fn+f7 hotkey. To increase screen brightness, press the fn+f8 hotkey. ■ If you leave your work, initiate standby or hibernation, or shut down the notebook. 2-28 Hardware and Software Guide
