CHAPTER 5: Managing Power • Copy programs from CDs or DVDs to the hard drive so you do not use battery power by running optical drives. • Use the CD or DVD drive only when necessary. This drive uses 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 60. Tip For more information about traveling with your notebook, see "Traveling with Your Notebook" on page 69. 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. • 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. 64

Copy programs from CDs or DVDs to the hard drive so

•
Use the CD or DVD drive only when necessary. This drive

•

.
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.
•
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.
