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 connections and exit modem
applications when you are not using them.
❏
Disconnect any external devices from the notebook that
are not plugged into an external power source.
❏
Stop or remove an inserted PC Card or ExpressCard.
❏
Disable or remove an inserted digital 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 must 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.
