Extending battery life

Conserving battery power

While using the battery to power your tablet PC, conserve power by:
■Modifying the power management settings for maximum power savings.
For more information, see “Changing power settings” on page135.
■Using Standby or Hibernate mode for maximum power savings while your
tablet PC is not in use. For more information, see “Activating and using
Hibernate mode” on page 140.
■Recharging the battery often, taking an extra battery, and fully recharging
the batteries before traveling. For more information, see “Recharging the
battery” on page 130 and “Changing batteries” on page 131.
■Keeping in mind that the display, processor, PC cards, wireless cards, and
peripheral devices all draw on the battery, so adjust properties and disable
unused devices and PC cards when operating on battery power.
■Using the optional diskette drive only when necessary. This drive uses a
large amount of power.
■Before unplugging the AC adapter, adjust the power mode and display
brightness to lower settings to prolong the battery’s charge. We
recommend operating in Max Battery mode to prolong the battery’s
charge—tap the taskbar’s Power/Battery icon to choose your power setting.
For more information, see “Changing the power scheme” on page136.
■Turning off the IEEE802.11b wireless networking.

Using alternate power sources

To extend battery life, use alternate power sources whenever possible.
■Use AC power whenever available to lengthen the battery’s usable life.
Leave the battery in place when using AC.
■Use AC power when installing software, writing to a CD and, using the
DVD player.
■If traveling internationally, take electrical adapters. Save the battery for
times when you cannot use a power adapter. If you plan on taking your
AC power ada pter, also take a single-plug surge prot ector.
