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(ies) 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(ies) 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 convertible notebook's battery: • Standby - while your convertible notebook is in Standby mode, 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 convertible notebook completely off. The next time you turn on your convertible notebook, it reads the memory information from the hard drive and opens the programs and documents that were open when you activated Hibernate mode. Using power saving modes Always save your work before using Standby mode. In Standby mode, your convertible 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. 68

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(ies) 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(ies) 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 convertible notebook’s battery:
•
Standby
- while your convertible notebook is in Standby
mode, 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 convertible notebook completely off. The next time
you turn on your convertible notebook, it reads the
memory information from the hard drive and opens the
programs and documents that were open when you
activated Hibernate mode.
Using power saving modes
Always save your work before using Standby mode. In Standby
mode, your convertible 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.
