Battery Conservation Procedures and Settings

Using the battery conservation procedures and settings described below extends the time that a battery pack can run the notebook from a single charge.

Conserving Power as You Work

To conserve power as you use the notebook:

■Turn off wireless and local area network (LAN) connections and exit modem applications when you are not using them.

■Disconnect external devices you are not using that are not connected to an external power source.

■Stop or remove a PC Card you are not using.

■Remove a CD or DVD you are not using.

■Use the Fn+F7 and Fn+F8 hotkeys to quickly lower and raise screen brightness as you need it.

■Use optional powered speakers instead of the internal speakers, or use the volume buttons to quickly raise and lower system volume as you need it.

■Turn off a device connected to the S-video connector by using the Fn+F4 hotkeys or by turning off support for the device in Windows.

■Run the notebook on external power while formatting a diskette.

■If you leave your work, initiate Standby or Hibernation or shut down the notebook.
