Extending battery life
Conserving battery power
To conserve power while using the battery to power your notebook:
■ Dim the display as low as is comfortable.
■ Remove PC Cards cards and IBM Microdrive cards when you do not need
them. Many PC Cards and Microdrive cards use a small amount of power
while inserted, even if they are not being used.
■ Modify the power management settings for maximum power savings. For
more information, see “Changing power settings” on page 163.
■ Close the LCD panel to turn off the display while you are not using your
notebook. The display stays off until you open the panel again.
■ Use Hibernate mode for maximum power savings while your notebook is
not in use. For more information, see “Activating and using Hibernate
mode” on page 167.
■ Use the disc drive only when necessary. These drives use a large amount
of power.
■ Recharge the battery often, take an extra battery, and fully recharge the
batteries before traveling. For more information, see “Recharging the
battery” on page 153 and “Changing batteries” on page 155.
Using alternate power sources
To extend battery life, use alternate power sources whenever possible.
■ 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 adapter, also take a single-plug surge protector.
■ If you will have access to an EmPower™ in-flight power receptacle or an
automobile cigarette lighter, use an airplane/automobile power adapter or
power inverter. Save the battery for times when you cannot use a power
adapter.
■ To find AC power outlets in airports, look for them next to support pillars,
in large areas such as boarding gates, and under banks of telephones.
