14 Chapter 2 Getting to know your computer
3 Connecting to a network
Your computer can travel with you wherever you go. But even at home, you can explore the globe and access information from millions of websites using your computer and a wired or wireless network connection. This chapter will help you get connected to that world.
Connecting to a wireless network
Wireless technology transfers data across radio waves instead of wires. Your computer may be equipped with one or more of the following wireless devices:
● Wireless local area network (WLAN) device—Connects the computer to wireless local area networks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporate offices, your home, and public places such as airports, restaurants, coffee shops, hotels, and universities. In a WLAN, the mobile wireless device in your computer communicates with a wireless router or a wireless access point.
● Bluetooth device—Creates a personal area network (PAN) to connect to other Bluetoothenabled devices such as computers, phones, printers, headsets, speakers, and cameras. In a
PAN, each device communicates directly with other devices, and devices must be relatively close together—typically within 10 meters (approximately 33 feet) of each other.
For more information about wireless technology, see the information and website links provided in
Help.
Using the wireless controls
You can control the wireless devices in your computer using these features:
● Wireless button, wireless switch, or wireless key (referred to in this chapter as the wireless button)
● Linux Network Manager software
● Operating system controls
Using the wireless button
The computer has a wireless button, one or more wireless devices, and one or two wireless lights, depending on the model. All of the wireless devices on your computer are enabled at the factory, so the wireless light is on (white) when you turn on the computer.
The wireless light indicates the overall power state of your wireless devices, not the status of individual devices. If the wireless light is white, at least one wireless device is on. If the wireless light is off, all wireless devices are off.
NOTE: On some models, the wireless light is amber when all wireless devices are off.
Because the wireless devices are enabled at the factory, you can use the wireless button to turn on or turn off the wireless devices simultaneously. Individual wireless devices can be controlled through
Linux Network Manager.
Connecting to a wireless network 15
Using operating system controls
The Network and Sharing Center allows you to set up a connection or network, connect to a network, manage wireless networks, and diagnose and repair network problems.

◦ Enable Wireless
For more information, select Computer > Help .
Using a WLAN
With a WLAN device, you can access a wireless local area network (WLAN), which is composed of other computers and accessories that are linked by a wireless router or a wireless access point.
NOTE: The terms wireless router and wireless access point are often used interchangeably.
● A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points that can accommodate a large number of computers and accessories and can separate critical network functions.
● A home or small office WLAN typically uses a wireless router, which allows several wireless and wired computers to share an Internet connection, a printer, and files without requiring additional pieces of hardware or software.
To use the WLAN device in your computer, you must connect to a WLAN infrastructure (provided through a service provider or a public or corporate network).
Using an Internet service provider
When you are setting up Internet access in your home, you must establish an account with an
Internet service provider (ISP). To purchase Internet service and a modem, contact a local ISP. The
ISP will help set up the modem, install a network cable to connect your wireless computer to the modem, and test the Internet service.
NOTE: Your ISP will give you a user ID and a password to use for Internet access. Record this information and store it in a safe place.
Setting up a WLAN
To set up a WLAN and connect to the Internet, you need the following equipment:
● A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from an Internet service provider
● A wireless router (2) (purchased separately)
● A wireless computer (3)
NOTE: Some modems have a built-in wireless router. Check with your ISP to determine what type of modem you have.
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
16 Chapter 3 Connecting to a network
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, see the information provided by your router manufacturer or your
ISP.
Configuring a wireless router
For help in setting up a WLAN, see the information provided by your router manufacturer or your ISP.
NOTE: It is recommended that you initially connect your new wireless computer to the router by using the network cable provided with the router. When the computer successfully connects to the
Internet, disconnect the cable, and access the Internet through your wireless network.
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 email that is not confidential and basic Internet surfing.
Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected signals. Take the following precautions to protect your WLAN:
● Use a firewall.
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.
● Use wireless encryption.
Wireless encryption uses security settings to encrypt and decrypt data that is transmitted over the network. For more information, see Help.
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1.
Be sure that the WLAN device is on. If the device is on, the wireless light is on. If the wireless light is off, press the wireless button.
NOTE: On some models, the wireless light is amber when all wireless devices are off.
2.
Click the network status icon in the notification area, at the far right of the taskbar.
3.
Select your WLAN from the list.
4.
Click Connect .
If the WLAN is a security-enabled WLAN, you are prompted to enter a security code. Type the code, and then click OK to complete the connection.
Connecting to a wireless network 17
NOTE: If no WLANs are listed, you may be out of range of a wireless router or access point.
NOTE: If you do not see the WLAN you want to connect to, click Open Network and Sharing
Center , and then click Set up a new connection or network . A list of options is displayed, allowing you to manually search for and connect to a network or to create a new network connection.
After the connection is made, place the mouse pointer over the network status icon in the notification area, at the far right of the taskbar, to verify the name and status of the connection.
NOTE: The functional range (how far your wireless signals travel) depends on WLAN implementation, router manufacturer, and interference from other electronic devices or structural barriers such as walls and floors.
Using Bluetooth wireless devices
A Bluetooth device provides short-range wireless communications that replace the physical cable connections that traditionally link electronic devices such as the following:
● Computers (desktop, notebook, PDA)
● Phones (cellular, cordless, smart phone)
● Imaging devices (printer, camera)
● Audio devices (headset, speakers)
● Mouse
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information about configuring and using Bluetooth devices, see the
Bluetooth software Help.
Connecting to a wired network
There are 2 kinds of wired connections: local area network (LAN) and modem connection. A LAN connection uses a network cable and is much faster than a modem, which uses telephone cable.
Both cables are sold separately.
WARNING!
To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a modem cable or telephone cable into an RJ-45 (network) jack.
Connecting to a local area network (LAN)
Use a LAN connection if you want to connect the computer directly to a router in your home (instead of working wirelessly), or if you want to connect to an existing network at your office.
Connecting to a LAN requires an 8-pin, RJ-45 network cable.
To connect the network cable, follow these steps:
1.
Plug the network cable into the network jack (1) on the computer.
18 Chapter 3 Connecting to a network
2.
Plug the other end of the network cable into a network wall jack (2) or router.
NOTE: If the network cable contains noise suppression circuitry (3) , which prevents interference from TV and radio reception, orient the circuitry end of the cable toward the computer.

8 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition. This chapter provides information about improving the performance of your computer by running system tools and by replacing a hard drive or adding memory. It also provides information about updating your programs and drivers, instructions for cleaning your computer, and tips for travelling with your computer.
Improving performance
Everyone wants a fast computer and by performing regular maintenance tasks, using a variety of system tools, you can drastically improve the performance of your computer. Also, as your computer gets older, you might consider installing larger drives and adding more memory.
Handling drives
Observe these precautions when handling drives:
● Before removing or installing a drive, shut down the computer. If you are unsure whether the computer is off, in the Suspend state, or in Hibernation, turn the computer on, and then shut it down through the operating system.
● 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.
● Do not use excessive force when inserting a drive into a drive bay.
● When the battery is the only source of power, be sure that the battery is sufficiently charged before writing to media.
● 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.
● Remove media from a drive before removing the drive from the drive bay, or traveling with, shipping, or storing a drive.
● 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.
● 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.

CAUTION: Never allow liquids to drip between the keys on the keyboard, even when you are cleaning the computer. This can permanently damage internal components.
● To clean and disinfect the TouchPad and keyboard, use a soft microfiber cloth or a static-free cloth without oil (such as a chamois cloth) moistened with an alcohol-free glass cleaner or use an acceptable germicidal disposable wipe.
● To prevent keys from sticking and to remove dust, lint, and particles from the keyboard, use a can of compressed air with a straw extension.
WARNING!
To reduce the risk of electric shock or damage to internal components, do not use a vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris on the keyboard surface.
Traveling with or shipping your computer
If you have to travel with or ship your computer, here are some tips to keep in mind to keep your equipment safe.
● Prepare the computer for traveling or shipping:
◦ Back up your information to an external drive.
◦ Remove all discs and all external media cards, such as digital storage cards, from the computer.
◦ Turn off, and then disconnect all external devices.
◦ Remove any media from the drive before removing the drive from a drive bay.
CAUTION: Perform this action before shipping, storing, or traveling with a drive. This will help reduce the risk of damage to the computer, damage to a drive, or loss of information.
◦ Shut down the computer.
● Take along a backup of your information. Keep the backup separate from the computer.
● When traveling by air, carry the computer as hand luggage; do not check it in with the rest of your luggage.
CAUTION: 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.
● If you plan to use the computer during a flight, listen for the in-flight announcement that tells you when you are allowed to use your computer. In-flight computer use is at the discretion of the airline.
Traveling with or shipping your computer 49
● If the computer will be unused and disconnected from external power for more than 2 weeks, remove the battery and store it separately.
● If you are shipping the computer or a drive, use suitable protective packaging and label the package “FRAGILE.”
● If the computer has a wireless device installed, the use of these devices may be restricted in some environments. Such restrictions may apply onboard aircraft, in hospitals, near explosives, and in hazardous locations. If you are uncertain of the policy that applies to the use of a particular device, ask for authorization to use your computer before you turn it on.
● If you are traveling internationally, follow these suggestions:
◦ Check the computer-related customs regulations for each country or region on your itinerary.
◦ Check the power cord and adapter requirements for each location in which you plan to use the computer. Voltage, frequency, and plug configurations vary.
WARNING!
To reduce the risk of electric shock, fire, or damage to the equipment, do not attempt to power the computer with a voltage converter kit sold for appliances.

When you use your computer to access email, a network, or the Internet, you potentially expose your computer to computer viruses, spyware, and other online threats. To help protect your computer,
Internet security software that includes antivirus and firewall features may be preinstalled on your computer as a trial offer. To provide ongoing protection against newly discovered viruses and other security risks, security software must be kept up to date. It is strongly recommended that you upgrade the security software trial offer or purchase the software of your choice in order to fully protect your computer.
Using antivirus software
Computer viruses can disable programs, utilities, or the operating system, or cause them to function abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any damage they have caused.
For more information about computer viruses, select Computer > Help .
Using firewall software
Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be software you install on your computer and/or network, or it can be a combination of both hardware and software.
There are two types of firewalls to consider:
● Host-based firewalls—Software that protects only the computer it is installed on.
● Network-based firewalls—Installed between your DSL or cable modem and your home network to protect all the computers on the network.
When a firewall is installed on a system, all data sent to and from the system is monitored and compared with a set of user-defined security criteria. Any data that does not meet those criteria is blocked.
Installing software updates
HP, operating system, and third-party software installed on your computer should be regularly updated to correct security problems and improve software performance. For more information, see
Updating programs and drivers on page 48
.
Installing security updates
Updates to the operating system and other software may have become available after the computer left the factory. To protect the computer from security breaches and computer viruses, install all critical operating system updates as soon as you receive an alert.

14 Electrostatic Discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for example, the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic components. To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions:
● If removal or installation instructions direct you to unplug the computer, unplug it after being properly grounded and before removing a cover.
● Keep components in their electrostatic-safe containers until you are ready to install them.
● Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
● Use nonmagnetic tools.
● Before handling components, discharge static electricity by touching an unpainted metal surface of the component.
● If you remove a component, place it in an electrostatic-safe container.
If you need more information about static electricity or assistance with component removal or installation, contact customer support.
