Conserving Battery Pack Power
To extend the time that a battery pack can run the notebook from
a single charge, use the following battery conservation settings
and procedures.
Conserving Power as You Work
To conserve power as you work:
Prevent devices you are not using from drawing power from
the notebook. For example:
Turn off wireless and local area network (LAN)
connections and close modem applications.
Disconnect from the notebook any external devices that
are not plugged into an external power source.
Stop or remove an inserted PC Card.
Disable or remove an inserted digital memory card.
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.
