    Using Internet security software
    When you use your tablet to access email, a network, or the Internet, you potentially expose your  tablet to tablet viruses, spyware, and other online threats. To help protect your tablet, Internet security  software that includes antivirus and firewall features may be preinstalled on your tablet 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 tablet.
    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.
    To provide ongoing protection against newly discovered viruses, antivirus software must be kept up to  date.
    An antivirus program may be preinstalled on your tablet. It is strongly recommended that you use the 
    antivirus program of your choice in order to fully protect your tablet.
    For more information about tablet viruses, from the Start screen, tap , type support, and then 
    select the 
    HP Support Assistant app, or from the Windows desktop, tap the question mark icon in the 
    notification area, at the far right of the taskbar.
    Using Internet security software21  
    						
    							Using firewall software
    Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be 
    software you install on your tablet 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 tablet 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, Windows, and third-party software installed on your tablet should be regularly updated to correct 
    security problems and improve software performance. For more information, see 
    Updating programs 
    and drivers on page 17.
    Installing critical security updates
    CAUTION:Microsoft sends out alerts regarding critical updates. To protect the tablet from security 
    breaches and computer viruses, install all critical updates from Microsoft as soon as you receive an 
    alert.
    You can install these updates manually or automatically.
    To view or change the settings:
    1.From the Start screen, tap , type control panel.
    2.Select System and Security, select Windows Update, select Change settings, and then follow 
    the on-screen instructions.
    Securing your wireless network
    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.
    Backing up your software applications and information
    Regularly back up your software applications and information to protect them from being permanently 
    lost or damaged through a virus attack or a software or hardware failure. For more information, see 
    Backup and recovery on page 25.

    							8Using HP PC Hardware Diagnostics (UEFI)
    HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run 
    diagnostic tests to determine whether the tablet hardware is functioning properly. The tool runs 
    outside the operating system so that it can isolate hardware failures from issues that are caused by  the operating system or other software components.
    To start HP PC Hardware Diagnostics (UEFI):
    1.Turn off the tablet.
    2.Press and hold the Volume down button.
    3.While continuing to hold the Volume down button, press the power button to turn on the tablet.
    The Startup menu is displayed.
    4.Press f2 at the bottom of the screen.
    5.When the diagnostic tool opens, select the type of diagnostic test you want to run, and then 
    follow the on-screen instructions.
    NOTE:If you need to stop a diagnostic test, press esc.23

    							9Backup and recovery
    To protect your information, use Windows backup and restore utilities to back up individual files and folders, back up your entire hard drive, or create system restore points. In case of system failure, you 
    can use the backup files to restore the contents of your tablet.
    1.Swipe from the right edge of the touch screen to display the charms, tap Search, and then tap 
    the search box.
    2.In the search box, type restore, and then select from the list of displayed options.
    NOTE:For detailed instructions on various backup and restore options, perform a search for these 
    topics in Windows Help and Support.
    In case of system instability, HP recommends that you print the recovery procedures and save them 
    for later use.
    NOTE:Windows includes the User Account Control feature to improve the security of your tablet. 
    You may be prompted for your permission or password for tasks such as installing software, running 
    utilities, or changing Windows settings. For more information, see Windows Help and Support.
    Backing up your information
    Recovery after a system failure is as good as your most recent backup. You should create system 
    repair media and your initial backup immediately after initial system setup. As you add new software 
    and data files, you should continue to back up your system on a regular basis to maintain a 
    reasonably current backup.
    For more information on the Windows backup features, see Windows Help and Support.
    Performing a system recovery
    NOTE:If you will be using F11 startup recovery or USB recovery media to recover your system, the 
    tablet battery must have at least 70% battery power remaining before starting the recovery process.
    In case of system failure or instability, the tablet provides the following tools to recover your files:
    ●Windows recovery tools: You can use Windows Backup and Restore to recover information you 
    have previously backed up. You can also use Windows Automatic Repair to fix problems that 
    might prevent Windows from starting correctly.
    NOTE:If you are unable to boot (start up) your tablet, contact support.
    Changing the boot device order
    To change the boot order so that you can boot from an external device:
    NOTE:An external flash drive is required to perform this procedure.
    1.If possible, back up all personal files.
    2.Shut down the tablet.
    3.Connect the external flash drive.

    Refresh option allows you to start fresh and keep what is important to you.
    The Windows Reset option allows you to perform detailed reformatting of your tablet, or remove 
    personal information before you give away or recycle your tablet. For more information on these 
    features, see Windows Help and Support.

    							11Electrostatic 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 tablet, damage to a drive, or loss of information, observe 
    these precautions:
    ●If removal or installation instructions direct you to unplug the tablet, first be sure that it is properly 
    grounded.
    ●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.
    ●If you remove a component, place it in an electrostatic-safe container.
