Conserving Battery Power
Using the battery conservation procedures and settings described
in this section 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 an optional PC Card you are not using. For
more information, refer to
Chapter 5, “Hardware
Components.”
■
Remove a CD or DVD that you are not using.
■
Use the
fn+f9
and
fn+f10
hotkeys to adjust screen brightness
as you need it.
■
Use optional powered speakers instead of the internal
speakers, or adjust system volume as you need it.
■
Turn off a device connected to the S-Video-out jack (select
models only) by using the
fn+f4
hotkey 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.
