CHAPTER 5: Managing Power

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, an automobile power outlet,
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.
Changing power modes
You can use the following power modes to lengthen
the life of your notebook’s battery:
• Sleep - while your notebook is in Sleep mode, it
switches to a low power state where devices,
such as the display and drives, turn off.
