1 Power control and light locations

The following illustration and table identify and describe the power control and light locations.

NOTE Your computer may look slightly different from the illustration in this chapter.

Component Description

(1) Power button

●

When the computer is off, press the button to turn on the
computer.

●

When the computer is on, press the button to initiate
hibernation.

●

When the computer is in standby, press the button briefly to
exit standby.

●

When the computer is in hibernation, press the button briefly
to exit hibernation.

If the computer has stopped responding and Microsoft® Windows®
shutdown procedures cannot be used, press and hold the power
button for at least 5 seconds to turn off the computer.

(2) Power lights* (2) On: The computer is on.

Blinking: The computer is in standby.

Off: The computer is off or in hibernation.

ENWW 1

Component Description

(3) fn+f5 Initiates standby.

(4) Battery light On: A battery is charging.

Blinking: A battery that is the only available power source has
reached a low-battery condition or a critical low-battery condition.

Off: If the computer is plugged into an external power source, the
light turns off when all batteries in the computer are fully charged.
If the computer is not plugged into an external power source, the
light stays off until the battery reaches a low-battery condition.

(5) Internal display switch Turns off the display and initiates standby if the display is closed

while the computer is on.

*The 2 power lights display the same information. The light on the power button is visible only when the computer is open. The
light on the front of the computer is visible whether the computer is open or closed.

2 Power sources

The computer runs on internal or external AC power. The following table indicates the best power
sources for common tasks.

NOTE Use only the provided AC adapter or one approved for use with this computer.

Task Recommended power source

Work in most software applications

●

Charged battery in the computer

●

External power supplied through one of the following
devices:

●

AC adapter included with the computer

●

Optional docking device or expansion product

●

Optional power adapter

Charge or calibrate a battery in the computer External power supplied through one of the following devices:

●

AC adapter included with the computer

●

Optional docking device or expansion product

●

Optional power adapter

WARNING! Do not charge the computer battery while

you are onboard aircraft.

Install or modify system software or write to a CD or DVD External power supplied through one of the following devices:

●

AC adapter included with the computer

●

Optional docking device or expansion product

●

Optional power adapter

ENWW 3

Connecting the AC adapter

WARNING! To reduce the risk of electric shock or damage to the equipment:

Plug the power cord into an AC outlet that is easily accessible at all times.

Disconnect power from the computer by unplugging the power cord from the AC outlet (not by
unplugging the power cord from the computer).

If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed)
3-pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin
adapter. The grounding pin is an important safety feature.

To connect the computer to external AC power, follow these steps:

1. Plug the AC adapter into the power connector (1) on the computer.

2. Plug the power cord into the AC adapter (2).

3. Plug the other end of the power cord into an AC outlet (3).

3 Standby and hibernation

Standby and hibernation are energy-saving features that conserve power and reduce startup time. They
can be initiated by you or by the system.

Standby

CAUTION To avoid a complete battery discharge, do not leave the computer in standby for

extended periods. Connect the computer to an external power source.

Standby reduces power to system components that are not in use. When standby is initiated, your work
is stored in random access memory (RAM), and then the screen is cleared. When the computer is in
standby, the power lights blink. When you resume from standby, your work returns to the screen where
you left off.

CAUTION To reduce the risk of information loss, save your work before initiating standby.

ENWW Standby 5

Hibernation

CAUTION If the configuration of the computer is changed during hibernation, resuming from

hibernation may not be possible. When the computer is in hibernation:

Do not connect the computer to or disconnect the computer from an optional docking device or
expansion product.

Do not add or remove memory modules.

Do not insert or remove any hard drives or optical drives.

Do not connect or disconnect external devices.

Do not insert or remove external media cards.

Hibernation saves your work to a hibernation file on the hard drive, and then shuts down the computer.
The power lights are turned off. When you restore from hibernation, your work returns to the screen
where you left off. If a power-on password has been set, the password must be entered to restore from
hibernation.

CAUTION To reduce the risk of information loss, save your work before initiating hibernation.

You can disable hibernation. However, if hibernation is disabled and the system reaches a low-battery
condition, the system will not automatically save your work while power is on or when standby has been
initiated.

Use Power Options in Microsoft® Windows® Control Panel to reenable hibernation:

▲

Select Start > Control Panel > Performance and Maintenance > Power Options > Hibernate
tab.

Be sure that the Enable hibernation check box is selected.

You can set the period of time that the system remains idle before it initiates hibernation:

1. Select Start > Control Panel > Performance and Maintenance > Power Options.

2. Click one of the intervals in the System hibernates list.

6 Chapter 3 Standby and hibernation ENWW

Initiating standby, hibernation or shutdown

The following sections explain when to initiate standby or hibernation and when to shut down the
computer.

NOTE You cannot initiate any type of networking communications or perform any computer

functions while the computer is in standby or hibernation.

When you leave your work

When standby is initiated, your work is stored in random access memory (RAM), and then the screen
is cleared. When the computer is in standby, it uses less power than when it is on. Your work returns
instantly to the screen when you resume from standby.

Initiating hibernation saves your work to a hibernation file on the hard drive, and then shuts down the
computer. When the computer is in hibernation, it uses much less power than when it is in standby.

When the computer will be unused and disconnected from external power for an extended period, shut
down the computer and remove the battery to extend the life of the battery.

When a reliable power supply is unavailable

Be sure that hibernation remains enabled, especially if you are operating the computer on battery power
and do not have access to an external power supply. If the battery fails, hibernation saves your work to
a hibernation file and shuts down the computer.

If you pause your work when the power supply is uncertain, you take one of the following actions:

●

Save your work, and then initiate standby.

●

Initiate hibernation.

●

Shut down the computer.
