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.
14 Chapter 3 Connecting to a network
Download from Www.Somanuals.com. All Manuals Search And Download.
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 Bluetooth-
enabled 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 and Support.
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)
●
●
HP Connection 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 HP
Connection Manager.
Using HP Connection Manager (select models only)
HP Connection Manager provides a central location for managing your wireless devices, and an
interface for sending and receiving SMS (text) messages. HP Connection Manager allows you to
manage the following devices:
●
●
Wireless local area network (WLAN)/Wi-Fi

HP Connection Manager provides information and notifications on connection status, power status,
and SMS (text) messages. Status information and notifications are provided in the notification area, at
the far right of the taskbar.
To open HP Connection Manager, select Start > All Programs > HP Help and Support > HP
Connection Manager.
For more details about using HP Connection Manager, see the HP Connection Manager software
Help.
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.
To use operating system controls, select Start > Control Panel > Network and Internet > Network
and Sharing Center.
For more information, select Start > Help and Support.
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.
16 Chapter 3 Connecting to a network
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
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 and Support.
Connecting to a wireless network 17
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
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.
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.

physically reorganizes) the fragmented files and folders on the hard drive so that the system can run
more efficiently.
NOTE: It is not necessary to run Disk Defragmenter on solid-state drives.
After you start Disk Defragmenter, it works without supervision. However, depending on the size of
your hard drive and the number of fragmented files, Disk Defragmenter may take more than an hour
to complete.
HP recommends defragmenting your hard drive at least once a month. You may set Disk
Defragmenter to run on a monthly schedule, but you can defragment your computer manually at any
time.
To run Disk Defragmenter:
1. Connect the computer to AC power.
2. Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
3. Follow the on-screen instructions.
For additional information, access the Disk Defragmenter software Help.
Using Disk Cleanup
Disk Cleanup searches the hard drive for unnecessary files that you can safely delete to free up disk
space and help the computer run more efficiently.
To run Disk Cleanup:
1. Select Start > All Programs > Accessories > System Tools > Disk Cleanup.
2. Follow the on-screen instructions.

11 Backing up, restoring, and recovering
Your computer includes tools provided by the operating system and HP to help you safeguard your
information and retrieve it if ever needed.
Creating backups
1. Use HP Recovery Manager to create recovery media immediately after you set up the working
computer.
2. As you add hardware and software programs, create system restore points.
3. As you add photos, video, music, and other personal files, create a backup of your system and
personal information.
Creating recovery media to recover the original system
After you successfully set up the computer, you should create recovery discs or a recovery flash drive
using HP Recovery Manager. You will need these recovery discs or recovery flash drive to perform a
system recovery should the hard drive become corrupted. A system recovery reinstalls the original
operating system, and then configures the settings for the default programs.
What you need to know
●
Only one set of recovery media can be created. Handle these recovery tools carefully, and keep
them in a safe place.
●
HP Recovery Manager examines the computer and determines the required storage capacity for
the flash drive or the number of blank DVD discs that will be required.
Use DVD-R, DVD+R, DVD-R DL, DVD+R DL discs or a flash drive. Do not use rewriteable discs
such as CD±RW, DVD±RW, double-layer DVD±RW, and BD-RE (rewritable Blu-ray) discs; they
are not compatible with HP Recovery Manager software.
●
If your computer does not include an integrated optical drive, you can use an optional external
optical drive (purchased separately) to create recovery discs, or you can obtain recovery discs
for your computer from the HP website. If you use an external optical drive, it must be connected
directly to a USB port on the computer, not to a USB port on an external device, such as a USB
hub.
●
●
Be sure that the computer is connected to AC power before you begin creating the recovery
media.
The creation process can take up to an hour or more. Do not interrupt the creation process.
60 Chapter 11 Backing up, restoring, and recovering
Download from Www.Somanuals.com. All Manuals Search And Download.
●
●
Store the recovery media in a safe location, separate from the computer.
If necessary, you can exit the program before you have finished creating the recovery media.
The next time you open HP Recovery Manager, you will be prompted to continue the process.
Creating the recovery media
1. Select Start and type recovery in the search field. Select Recovery Manager from the list.
Allow the action to continue, if prompted.
2. Click Recovery Media Creation.
3. Follow the on-screen instructions to continue.
Creating system restore points
A system restore point is a snapshot of certain hard drive contents saved by Windows System
Restore at a specific time. A restore point contains information such as registry settings that Windows
uses. Restoring to a previous restore point allows you to reverse changes that have been made to the
system since the restore point was created.
Restoring to an earlier system restore point does not affect data files saved or emails created since
the last restore point, but it does affect software you may have installed.
For example, if you download a photo from a digital camera and then restore the computer to the
state it was on the previous day, the photo remains on the computer.
However, if you install photo viewing software and then restore your computer to the state it was on
the previous day, the software will be uninstalled, and you won't be able to use it.
What you need to know
●
●
If you restore to a restore point and then change your mind, you can undo the restoration.
You should create system restore points:
◦
◦
Before you add or change software or hardware
Periodically, whenever the computer is running normally

Troubleshooting
Wireless connection problems
Some possible causes for wireless connection problems include the following:
●
●
●
●
Wireless device is not turned on.
Wireless device is not installed correctly or has been disabled.
Wireless device encountered interference from other devices.
Wireless device or router hardware has failed.
NOTE: Wireless networking devices are included with select computer models only. If wireless
networking is not listed in the feature list on the side of the original computer package, you may add
wireless networking capability to the computer by purchasing a wireless networking device.
Cannot connect to a WLAN
If you have a problem connecting to a WLAN, confirm that the integrated WLAN device is turned on
and properly installed on your computer.
1. If the wireless light is off or amber, press the wireless button, wireless switch, or wireless key to
turn the wireless device on.
2. Then try connecting to the WLAN again.
If you are still unable to connect, follow the steps below.
1. Select Start > Control Panel > System and Security.
2. In the System area, click Device Manager.
3. Click the arrow next to Network adapters to expand the list and show all adapters.
4. Identify the WLAN device from the Network adapters list. The listing for a WLAN device may
include the term wireless, wireless LAN, WLAN, or 802.11.
If no WLAN device is listed, either your computer does not have an integrated WLAN device, or
the driver for the WLAN device is not properly installed.
For more information about troubleshooting WLANs, see the website links provided in Help and
Support.
Cannot connect to a preferred network
You may not be able to connect to a preferred network because it is a security-enabled WLAN. You
must have the security code to connect to this type of WLAN. See the next section for additional
information.

If entering a security code is not the problem, you may have a corrupted WLAN connection. Many
times, Windows can automatically repair a corrupted WLAN connection.
●
If there is a network status icon in the notification area, at the far right of the taskbar, right-click
the icon, and then click Troubleshoot problems.
Windows resets your network device and attempts to reconnect to one of the preferred
networks.
●
If there is no network status icon in the notification area, follow these steps:
1. Start > Control Panel > Network and Internet > Network and Sharing Center.
2. Click Troubleshoot problems and select the network you wish to repair.
Current network security codes are unavailable
If you are prompted for a security code (or network key) or a name (SSID) when connecting to a
WLAN, the network is protected by security. You must have the current codes to make a connection
on a secure network. The SSID and security code are alphanumeric codes that you enter into your
computer to identify your computer to the network.
●
For a network connected to your personal wireless router, review the router user guide for
instructions on setting up the same codes on both the router and the WLAN device.
●
For a private network, such as a network in an office or at a public Internet chat room, contact
the network administrator to obtain the codes, and then enter the codes when prompted to do
so.
Some networks change the SSID or network keys used in their routers or access points on a
regular basis to improve security. You must change the corresponding code in your computer
accordingly.
If you are provided with new wireless network keys and SSID for a network, and if you have
previously connected to that network, follow the steps below to connect to the network:
1. Select Start > Control Panel > Network and Internet > Network and Sharing Center.
2. In the left panel, click Manage wireless networks.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
are active, several will be displayed.
3. Select the network in the list, right-click the network, and then click Properties.
NOTE: If the network you want is not listed, check with the network administrator to be sure
that the router or access point is operating.
4. Click the Security tab and enter the correct wireless encryption data into the Network security
key box.
5. Click OK to save these settings.

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 support.
