CHAPTER 5: Managing Power
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.
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.
