Taking your notebook PC with you

This section gives you tips and hints to consider when moving around or traveling

with your computer.

Disconnecting from the desktop

Follow these steps to disconnect your computer from external accessories:

1 Save any open files.

2 Remove any media, floppy disks or compact disks from the drive(s).

3 Shut down the computer.

4 Close the display cover.

5 Disconnect the cord from the AC adapter.

6 Disconnect the keyboard, pointing device, printer, external monitor and other

external devices.

7 Disconnect the Kensington lock if you are using one to secure the computer.

Moving around

When you are just moving within short distances, for example, from your office desk

to a meeting room.

Preparing the computer

Before moving the computer, close and latch the display cover to place it in Sleep

mode. You can now safely take the computer anywhere you go within the building.

To bring the computer out of Sleep mode, open the display; then press and release

the power button.

If you are taking the computer to a client's office or a different building, you may

choose to shut down the computer:

press the Windows key + <C> and click Start > Shut Down.

Or:

You can put the computer in Sleep mode by pressing <Fn> + <F4>. Then close and

latch the display.

When you are ready to use the computer again, unlatch and open the display; then

press and release the power button.

Note: If the Sleep indicator is off, the computer has entered

Hibernation mode and is turned off. If the power indicator is off but the

Sleep indicator is on, the computer has entered Sleep mode. In both

cases, press and release the power button to turn the computer back

30

on. Note that the computer may enter Hibernation mode after being in

Sleep mode for a period of time.

What to bring to meetings

If your meeting is relatively short, you probably do not need to bring anything with

you other than your computer. If your meeting will be longer, or if your battery is not

fully charged, you may want to bring the AC adapter with you to plug in your

computer in the meeting room.

If the meeting room does not have an electrical outlet, reduce the drain on the

battery by putting the computer in Sleep mode. Press <Fn> + <F4> or close the

display cover whenever you are not actively using the computer. To resume, open

the display (if closed), then press and release the power button.

Taking the computer home

When you are moving from your office to your home or vice versa.

Preparing the computer

After disconnecting the computer from your desktop, follow these steps to prepare

the computer for the trip home:

• Check that you have removed all media and compact discs from the drive(s).

Failure to remove the media can damage the drive head.

• Pack the computer in a protective case that can prevent the computer from

sliding around and cushion it if it should fall.

Caution: Avoid packing items next to the top cover of the computer.

Pressure against the top cover can damage the screen.

What to take with you

Unless you have some items at home, take the following items with you:

• AC adapter and power cord.

• The printed setup poster.

Special considerations

Follow these guidelines to protect your computer while traveling to and

from work:

• Minimize the effects of temperature changes by keeping the computer with you.

• If you need to stop for an extended period of time and cannot carry the

computer with you, leave the computer in the trunk of the car to avoid exposing

the computer to excessive heat.

31

• Changes in temperature and humidity can cause condensation. Allow the

computer to return to room temperature, and inspect the screen for

condensation before turning on the computer. If the temperature change is

greater than 10° C (18° F), allow the computer to come to room temperature

slowly. If possible, leave the computer for 30 minutes in an environment with a

temperature between outside and room temperature.

Setting up a home office

If you frequently work on your computer at home, you may want to purchase a

second AC adapter for use at home. With a second AC adapter, you can avoid

carrying the extra weight to and from home.

If you use your computer at home for significant periods of time, you might also want

to add an external keyboard, monitor or mouse.

Traveling with the computer

When you are moving within a larger distance, for instance, from your office building

to a client's office building or traveling locally.

Preparing the computer

Prepare the computer as if you were taking it home. Make sure that the battery in the

computer is charged. Airport security may require you to turn on your computer

when carrying it into the gate area.

What to take with you

Take the following items with you:

• AC adapter

• Spare, fully-charged battery pack(s)

• Additional printer driver files if you plan to use another printer

Special considerations

In addition to the guidelines for taking the computer home, follow these guidelines to

protect your computer while traveling:

• Always take the computer as carry-on luggage.

• If possible, have the computer inspected by hand. Airport security X-ray

machines are safe, but do not put the computer through a metal detector.

• Avoid exposing floppy disks to hand-held metal detectors.

Traveling internationally with the computer

When you are moving from country to country.

32

Preparing the computer

Prepare the computer as you would normally prepare it for traveling.

What to bring with you

Bring the following items with you:

• AC adapter

• Power cords that are appropriate for the country to which you

are traveling

• Spare, fully-charged battery packs

• Additional printer driver files if you plan to use another printer

• Proof of purchase, in case you need to show it to customs officials

• International Travelers Warranty passport

Special considerations

Follow the same special considerations as when traveling with the computer.

In addition, these tips are useful when traveling internationally:

• When traveling in another country, check that the local AC voltage and the AC

adapter power cord specifications are compatible. If not, purchase a power

cord that is compatible with the local AC voltage. Do not use converter kits sold

for appliances to power the computer.

• If you are using the modem, check if the modem and connector are compatible

with the telecommunications system of the country you are traveling in.

Securing your computer

Your computer is a valuable investment that you need to take care of. Learn how to

protect and take care of your computer.

Security features include hardware and software locks — a security notch

and passwords.

Using a computer security lock

The notebook comes with a Kensington-compatible security slot for a

security lock.

Wrap a computer security lock cable around an immovable object such as a table or

handle of a locked drawer. Insert the lock into the notch and turn the key to secure

the lock. Some keyless models are also available.

Using passwords

Passwords protect your computer from unauthorized access. Setting these

passwords creates several different levels of protection for your computer

and data:

• Supervisor Password prevents unauthorized entry into the BIOS utility. Once

set, you must enter this password to gain access to the BIOS utility. See "BIOS

utility" on page 44.

• User Password secures your computer against unauthorized use. Combine the

use of this password with password checkpoints on boot-up and resume from

Hibernation for maximum security.

• Password on Boot secures your computer against unauthorized use. Combine

the use of this password with password checkpoints on boot-up and resume

from Hibernation for maximum security.

Important! Do not forget your Supervisor Password! If you forget your

password, please get in touch with your dealer or an authorized

service center.

34

Entering passwords

When a password is set, a password prompt appears in the center of the

display screen.

• When the Supervisor Password is set, a prompt appears when you press <F2>

to enter the BIOS utility at boot-up.

• Type the Supervisor Password and press <Enter> to access the BIOS utility. If

you enter the password incorrectly, a warning message appears. Try again and

press <Enter>.

• When the User Password is set and the password on boot parameter is

enabled, a prompt appears at boot-up.

• Type the User Password and press <Enter> to use the computer. If you enter

the password incorrectly, a warning message appears. Try again and press

<Enter>.

Important! You have three chances to enter a password. If you fail to

enter the password correctly after three tries, the system halts. Press

and hold the power button for four seconds to shut down the

computer. Then turn on the computer again, and try again.

Setting passwords

You can set passwords using the BIOS utility.
