Using a WLAN 17
Setting up a new WLAN
Required equipment:
● A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from
an Internet service provider (ISP)
● A wireless router (purchased separately) (2)
● The wireless computer (3)
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
NOTE: Some cable modems include a built-in router. Check with your ISP to see if you need a
separate router.
NOTE: When setting up a wireless connection, be sure that your computer and wireless router are
synchronized. To synchronize your computer and wireless router, turn your computer and wireless
router off and then back on.
As your network grows, additional wireless and wired computers can be connected to the network to
access the Internet.
For help in setting up your WLAN, refer to the information provided by your router manufacturer or
your ISP.
18 Chapter 3 Networking
Protecting your WLAN
When you set up a WLAN or access an existing WLAN, always enable security features to protect
your network from unauthorized access. WLANs in public areas (hotspots) like coffee shops and
airports may not provide any security. If you are concerned about the security of your computer in a
hotspot, limit your network activities to e-mail that is not confidential and basic Internet surfing.
Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected
signals. You can use the following precautions to protect your WLAN:
● Use a Firewall—Checks both data and requests for data that are sent to your network, and
discards any suspicious items. Firewalls are available in both software and hardware. Some
networks use a combination of both types.
Encrypt your data—Wi-Fi Protected Access (WPA and WPA2) encrypts and decrypts data
●
transmitted over the network. WPA uses Advanced Encryption Standard (AES) and Temporal
Key Integrity Protocol (TKIP) to dynamically generate a new key for every packet. It also
generates different sets of keys for each computer on the network. Wired Equivalent Privacy
(WEP) encrypts data before it is transmitted using a WEP key. Without the correct key, others
will not be able to use the WLAN.
Roaming to another network
When you move your computer within range of another WLAN, the operating system attempts to
connect to that network. If the attempt is successful, your computer is automatically connected to the
new network. If the operating system does not recognize the new network, follow the same procedure
you used initially to connect to your WLAN.
Using a WLAN 19
Using Bluetooth wireless devices (select models only)
A Bluetooth device provides short-range wireless communications that replace the physical cable
connections that traditionally link electronic devices such as the following:
Computers
●
Phones
●
Audio devices
●
The strength of Bluetooth is in synchronizing information transfers between your computer and
wireless devices. The inability to consistently connect two or more computers to share the Internet
through Bluetooth is a limitation of Bluetooth and the operating system.
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information on configuring and using Bluetooth devices, refer to the
Bluetooth software Help.
Connecting to a wired network
Using a modem (select models only)
A modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable
(purchased separately). In some countries or regions, a specific modem cable adapter is also
required. Jacks for digital PBX systems may resemble analog telephone jacks, but they are not
compatible with the modem.
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem or telephone cable into the RJ-45 (network) jack.
If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end of the cable (2) toward the computer.
20 Chapter 3 Networking
Connecting a modem cable
1. Plug the modem cable into the modem jack (1) on the computer.
2. Plug the modem cable into the RJ-11 telephone wall jack (2).

Telephone jacks vary by country or region. To use the modem and the modem cable outside the
country or region in which you purchased the computer, you must obtain a country- or region-specific
modem cable adapter.
To connect the modem to an analog telephone line that does not have an RJ-11 telephone jack,
follow these steps:
1. Plug the modem cable into the modem jack (1) on the computer.
2. Plug the modem cable into the modem cable adapter (2).
3. Plug the modem cable adapter (3) into the telephone wall jack.
Connecting to a wired network 21
Connecting to a local area network (LAN) (select models only)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the computer.
To connect the network cable:
1. Plug the network cable into the network jack (1) on the computer.
2. Plug the other end of the cable into a network wall jack (2).

Handling drives
Drives are fragile computer components that must be handled with care. Refer to the following
cautions before handling drives. Additional cautions are included with the procedures to which they
apply.
Observe these precautions:
Before you move a computer that is connected to an external hard drive, initiate Suspend and
●
allow the screen to clear, or properly disconnect the external hard drive.
Before handling a drive, discharge static electricity by touching the unpainted metal surface of
●
the drive.
Do not touch the connector pins on a removable drive or on the computer.
●
Handle a drive carefully; do not drop a drive or place items on it.
●
Before removing or inserting a drive, shut down the computer. If you are unsure whether the
●
computer is off, in Suspend, or in Hibernation, turn the computer on, and then shut it down
through the operating system.
● Do not use excessive force when inserting a drive into a drive bay.
Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The
●
write process is sensitive to vibration.
● When the battery is the only source of power, be sure that the battery is sufficiently charged
before writing to media.
● Avoid exposing a drive to temperature or humidity extremes.
● Avoid exposing a drive to liquids. Do not spray the drive with cleaning products.
Handling drives 45
Remove media from a drive before removing the drive from the drive bay, or traveling with,
●
shipping, or storing a drive.
If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
●
packaging and label the package “FRAGILE.”
Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport
●
walk-through devices and security wands. Airport conveyer belts and similar security devices
that check carry-on baggage use X-rays instead of magnetism and do not damage drives.

13 MultiBoot
About the boot device order
As the computer starts, the system attempts to boot from enabled boot devices. The MultiBoot utility,
which is enabled at the factory, controls the order in which the system selects a boot device. Boot
devices can include optical drives, diskette drives, a network interface card (NIC), hard drives, and
USB devices. Boot devices contain bootable media or files that the computer needs to start and
operate properly.
NOTE: Some boot devices must be enabled in Computer Setup before they can be included in the
boot order.
The factory setting is for the computer to select the boot device by searching enabled boot devices
and drive bay locations in the following order:
NOTE: Some of the boot devices and drive bay locations listed may not be supported on your
computer.
Notebook upgrade bay
●
Optical drive
●
● Notebook hard drive
● USB diskette drive
USB CD-ROM
●
USB hard drive
●
Notebook Ethernet
●
Secure Digital (SD) Memory Card
●
● Docking station upgrade bay
● External SATA drive
You can change the order in which the computer searches for a boot device by changing the boot
order in Computer Setup. You can also press esc while the “Press the ESC key for Startup Menu”
message is displayed at the bottom of the screen, and then press f9. Pressing f9 displays a menu
that shows the current boot devices and allows you to select a boot device. Or, you can use MultiBoot
Express to set the computer to prompt you for a boot location each time the computer turns on or
restarts.
84 Chapter 13 MultiBoot
Enabling boot devices in Computer Setup
The computer will boot to a USB device or a NIC device only if the device has first been enabled in

Enabling boot devices in Computer Setup 85
Considering boot order changes
Before changing the boot order, note the following considerations:
When the computer restarts after the boot order has been changed, the computer attempts to
●
start using the new boot order.
If there is more than one type of boot device, the computer attempts to boot using the first device
●
of each type of boot device (except for optical devices). For example, if the computer is
connected to an optional docking device (select models only) that contains a hard drive, this
hard drive will be shown in the boot order as a USB hard drive. If the system attempts to boot
from this USB hard drive and fails, it will not attempt to boot to the hard drive in the hard drive
bay. Instead, it will try to boot to the next type of device in the boot order. However, if there are
two optical devices, and the first optical device does not boot (either because it does not contain
media or the media is not a boot disc), the system will try to boot to the second optical device.
Changing the boot order also changes the logical drive designations. For example, if you start up
●
from a CD-ROM drive with a disc formatted as drive C, that CD-ROM drive becomes drive C and
the hard drive in the hard drive bay becomes drive D.
The computer will boot from a NIC device only if the device has been enabled in the Built-In
●
Device Options menu of Computer Setup and if booting from the device has been enabled in the
Boot Options menu of Computer Setup. Booting from a NIC does not affect logical drive
designations because no drive letter is associated with the NIC.
Drives in an optional docking device (select models only) are treated like external USB devices
●
in the boot order.
86 Chapter 13 MultiBoot
