Using Alternate Power Sources; Changing Power Modes - Gateway 200 User Manual

Chapter 8: 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 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:
■ Standby - while your notebook is in Standby, it switches to a low power
state where devices, such as the display and drives, turn off.
■ Hibernate - (also called save to disk) writes all current memory (RAM)
information to the hard drive, then turns your notebook completely off.
The next time you turn on your notebook, it reads the memory
information from the hard drive and opens the programs and documents
that were open when you activated Hibernate mode. For more information
on using Hibernate mode, see "Activating and using Hibernate mode" on
page 168.
Using power saving modes
Always save your work before using Standby mode. In Standby mode, your
notebook reduces or turns off the power to most devices except memory.
However, the information in memory is not saved to the hard drive. If power
is interrupted, the information is lost.
When in Hibernate mode, your computer saves all memory information to the
hard drive, then turns the power completely off.
