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 and Support. Using the wireless controls You can control the wireless devices in your computer using these features: 18 ● Wireless button, wireless switch, or wireless key (referred to in this chapter as the wireless button) ● HP Connection Manager software (select models only) ● Operating system controls Chapter 3 Connecting to a network 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 (select models only). 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 ● Bluetooth HP Connection Manager provides information and notifications on connection status, power status, subscriber identity module (SIM) details, 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.

Connecting to a wireless network 19 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. 20 Chapter 3 Connecting to a network 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 21 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 (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 (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. 22 Chapter 3 Connecting to a network 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.

Some drives can only read information, but others can also write (burn) information onto a blank disc. Use these tips for best performance of your optical drive: ● When the battery is the only source of power, be sure the battery is sufficiently charged before writing to media. ● 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. ● Make sure you have installed the latest software updates for the drive. ● If the disc you are using is not clean, wipe it with a dry, lint-free, soft cloth. Your computer may include an optical drive that supports one or more of the following disc technologies: ● ● ● CD—A compact disc stores data that is read by a laser from the optical disc drive. The following CD formats are available: ◦ CD-Recordable (CD-R), which allows the computer to read information and to record information one time on the CD. Once the information is recorded on the CD-R disc, it cannot be changed or erased; it is permanent. ◦ CD-Re-Writable (CD-RW), which allows you to read information and record information many times to the CD. Information on the CD can be erased. DVD—A digital video disc is a high-capacity optical disc. It can store more information than a CD. A double-sided DVD can store up to 17 GB. The following DVD formats are available: ◦ DVD-Recordable (DVD-R or DVD+R), which allow the computer to read information and to record information one time on the DVD. After the information is recorded on the disc, it cannot be changed or erased; it is permanent. The DVDs can be used in DVD±R drives. ◦ DVD-Re-Writable (DVD-RW or DVD+RW), which allow to read information and record information many times to the disc. Information on the disc can be erased. The DVDs can be used in DVD±R drives. BD—a Blu-ray Disc holds more information than the other optical discs and they can used to record, rewrite, and play back high-definition (HD) video. Note the following when using BDs: 52 ● CyberLink PowerDVD is installed on the computer to play BD movies. ● Playing most BD movie titles on an external display requires an HDMI digital connection. The computer can support up to 1080p resolution on an external display, which requires a 1080pcapable HDTV or monitor. ● Attempting to play a BD movie simultaneously on both the internal and an external display may cause an error, so choose only one. ● For copy protection purposes, Advanced Access Content System (AACS) keys are integrated into the computer. AACS keys require occasional renewal to support playback of new BD movie releases. The CyberLink PowerDVD program will request an update to continue playback when Chapter 7 Managing and sharing information such a BD movie release is inserted in the drive. Follow the on-screen instructions to install the update. ● If lines appear on the display when viewing a BD, they may be caused by interference from the wireless network.

Chapter 7 Managing and sharing information 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 tools such as Disk Defragmenter and Disk Cleanup 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 tools such as Disk Defragmenter and Disk Cleanup, 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 Sleep 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. Improving performance 55 ● 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 Sleep and allow the screen to clear, or properly disconnect the external hard drive. Replacing a hard drive CAUTION: Drives are fragile computer components that must be handled with care. Do not drop a drive, place items on it, or expose it to liquids, or temperature or humidity extremes. See Handling drives on page 55 for specific precautions when handling drives. CAUTION: To prevent information loss or an unresponsive system: Before removing or installing a drive, shut down the computer. If you are unsure whether the computer is off, in the Sleep state, or in Hibernation, turn the computer on, and then shut it down through the operating system. 1. Save your work and shut down the computer. 2. Disconnect all external devices connected to the computer. 3. Unplug the power cord from the AC outlet. 4. Turn the computer upside down on a flat surface. 5. Remove the battery from the computer. NOTE: For more information, go to Removing a user-replaceable battery on page 45.

A short time after the end of one of these events, HP 3D DriveGuard returns the hard drive to normal operation. NOTE: Because solid-state drives (SSD) lack moving parts, HP 3D DriveGuard is unnecessary. NOTE: Hard drives in the primary hard drive bay or in the secondary hard drive bay are protected by HP 3D DriveGuard. Hard drives connected to USB ports are not covered by HP 3D DriveGuard. For more information, see the HP 3D DriveGuard software Help. Using Disk Defragmenter As you use your computer over time, the files on the hard drive become fragmented. A fragmented drive means data on your drive is not contiguous (sequential) and, because of this, the hard drive works harder to locate files, thus slowing down the computer. Disk Defragmenter consolidates (or 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: 58 1. Select Start > All Programs > Accessories > System Tools > Disk Cleanup. 2. Follow the on-screen instructions. Chapter 8 Maintaining your computer Adding or replacing memory modules Adding memory can help improve your computer's performance. Your computer is like your physical work area. The hard drive is the filing cabinet where you store your work and the memory is the desk where you work. When your memory isn’t big enough to hold all your work easily, like a desk overflowing with work, your productivity slows down. A great solution to improve performance is to expand the amount of memory you have in your computer. The computer has two memory module slots. The memory module slots are located on the bottom of the computer under the service door. The memory capacity of the computer can be upgraded by adding a memory module or replacing the existing memory module in one of the memory module slots. WARNING! To reduce the risk of electric shock and damage to the equipment, unplug the power cord and remove all batteries before installing a memory module. CAUTION: Electrostatic discharge (ESD) can damage electronic components. Before beginning any procedure, ensure that you are discharged of static electricity by touching a grounded metal object.

Using System Diagnostics 73 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. 74 Chapter 11 Backing up, restoring, and recovering 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. ● 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. To recover, see Recovering the original system using HP Recovery Manager on page 78. 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. Creating backups 75 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 System Restore also saves shadow copies of files that have been changed since the last restore point was created. For more information about using shadow copies to restore, see Help and Support. Creating a system restore point 1. Select Start > Control Panel > System and Security > System. 2. In the left pane, click System Protection. 3. Click the System Protection tab. 4. Click Create, and follow the on-screen instructions. To restore, see Restoring to a previous system restore point on page 78. Backing up system and personal information Your computer stores information that is important to you, such as files, emails, and photos, and you will want to keep that information even if you download a virus or the system stops working properly. How completely you are able to recover your files depends on how recent your backup is. As you add new software and data files, you should create backups on a regular basis. Tips for a successful backup ● Number backup discs before inserting them into the optical drive. ● Store personal files in the Documents, Music, Pictures, and Videos libraries, and back up these folders periodically. ● Save customized settings in a window, toolbar, or menu bar by taking a screen shot of your settings. The screen shot can be a time-saver if you have to re-enter your preferences. To create a screen shot: 1. Display the screen you want to save. 2. Copy the screen image: To copy only the active window, press alt+prt sc. To copy the entire screen, press prt sc. 76 3. Open a word-processing document or graphics editing program, and then select Edit > Paste. The screen image is added to the document. 4. Save and print the document. Chapter 11 Backing up, restoring, and recovering What you need to know ● You can back up your information to an optional external hard drive, a flash drive, a network drive, or discs. ● Connect the computer to AC power during backups. ● Allow enough time for the backup. Depending on files sizes, it may take more than an hour. ● Verify the amount of free space on your backup storage device before you back up. ● You should back up: ◦ Before adding or changing software or hardware. ◦ Before the computer is repaired or restored. ◦ On a regular schedule to be sure you have recent copies of personal information. ◦ After you add many files—for example, if you saved videos from a birthday party. ◦ Before using antivirus software to remove a malicious program. ◦ After adding information that is hard to replace, such as pictures, videos, music, project files, or data records. Creating a backup using Windows Backup and Restore Windows allows you to back up files using Windows Backup and Restore. You can select the level you want to back up, from individual folders to drives. The backups are compressed to save space. To back up: 1. Select Start > Control Panel > System and Security > Backup and Restore. 2. Follow the on-screen instructions to schedule and create a backup. NOTE: Windows includes the User Account Control feature to improve the security of the computer. You may be prompted for your permission or password for tasks such as installing software, running utilities, or changing Windows settings. See Help and Support for more information. To restore, see Restoring specific files using Windows Backup and Restore on page 78. Creating backups 77 Restore and recovery Restoring to a previous system restore point Sometimes installing a software program causes your computer or Windows to behave unpredictably. Usually uninstalling the software fixes the problems. If uninstalling does not fix the problems, you can restore the computer to a previous system restore point (created at an earlier date and time). To restore to a previous system restore point, when the computer was running correctly: 1. Select Start > Control Panel > System and Security > System. 2. In the left pane, click System Protection. 3. Click the System Protection tab. 4. Click System Restore, and follow the on-screen instructions. Restoring specific files If files are accidentally deleted from the hard disk and they can no longer be restored from the Recycle Bin, or if files become corrupt, restoring specific files is useful. Restoring specific files is also useful if you ever choose to recover the original system using HP Recovery Manager. You can only restore specific files that you have backed up before. Restoring specific files using Windows Backup and Restore Windows allows you to restore files that were backed up using Windows Backup and Restore: 1. Select Start > Control Panel > System and Security > Backup and Restore. 2. Follow the on-screen instructions to restore your backup. NOTE: Windows includes the User Account Control feature to improve the security of the computer. You may be prompted for your permission or password for tasks such as installing software, running utilities, or changing Windows settings. See Help and Support for more information. Recovering the original system using HP Recovery Manager HP Recovery Manager software allows you to repair or recover the computer to its original factory state. What you need to know 78 ● HP Recovery Manager recovers only software that was installed at the factory. For software not provided with this computer, you must either download the software from the manufacturer's website or reinstall the software from the disc provided by the manufacturer. ● A system recovery should be used as a final attempt to correct computer issues.
