    							7 Maintaining your computer
    It is important to perform regular maintenance to keep your computer in optimal condition. This chapter
    explains how to use tools like Disk Defragmenter and Disk Cleanup. It also provides instructions for updating
    programs and drivers, steps to clean the computer, and tips for traveling with (or shipping) the computer.
    Improving performance
    You can improve the performance of your computer by performing regular maintenance tasks with tools
    such as Disk Defragmenter and Disk Cleanup.
    Using Disk Defragmenter
    HP recommends using Disk Defragmenter to defragment your hard drive at least once a month.
    NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
    To run Disk Defragmenter:
    1.Connect the computer to AC power.
    2.Type defragment in the taskbar search box, and then select Defragment and optimize your drives.
    3.Follow the on-screen instructions.
    For additional information, access the Disk Defragmenter software Help.
    Using Disk Cleanup
    Use Disk Cleanup to search 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.Type disk in the taskbar search box, and then select Free up disk space by deleting unnecessary files
    or Uninstall apps to free up disk space.
    2.Follow the on-screen instructions.
    Using HP 3D DriveGuard (select products only)
    HP 3D DriveGuard protects a hard drive by parking the drive and halting data requests under either of the
    following conditions:
    ●
    You drop the computer.
    ●
    You move the computer with the display closed while the computer is running on battery power.
    A short time after the end of one of these events, HP 3D DriveGuard returns the hard drive to normal
    operation.
    NOTE:Only internal hard drives are protected by HP 3D DriveGuard. A hard drive installed in an optional
    docking device or connected to a USB port is not protected by HP 3D DriveGuard.
    Improving performance 39 
    						
    							NOTE:Because solid-state drives (SSDs) lack moving parts, HP 3D DriveGuard is unnecessary for these
    drives.
    For more information, see the HP 3D DriveGuard software Help.
    Identifying HP 3D DriveGuard status
    The hard drive light on the computer changes color to show that the drive in a primary hard drive bay and/or
    the drive in a secondary hard drive bay (select products only) is parked. To determine whether a drive is
    currently protected or whether it is parked, view the icon on the Windows desktop in the notification area, at
    the far right of the taskbar.
    Updating programs and drivers
    HP recommends that you update your programs and drivers on a regular basis. Updates can resolve issues
    and bring new features and options to your computer. For example, older graphics components might not
    work well with the most recent gaming software. Without the latest driver, you would not be getting the
    most out of your equipment.
    Go to 
    http://www.hp.com/support to download the latest versions of HP programs and drivers. In addition,
    register to receive automatic notifications when updates become available.
    If you would like to update your programs and drivers, follow these instructions:
    1.Type support in the taskbar search box, and then select the HP Support Assistant app.
    - or -
    Click the question mark icon in the taskbar.
    2.Select My PC, select the Updates tab, and then select Check for updates and messages.
    3.Follow the on-screen instructions.
    Cleaning your computer
    Use the following products to safely clean your computer:
    ●
    Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration (for example, disposable
    wipes, which come in a variety of brands)
    ●
    Alcohol-free glass-cleaning fluid
    ●
    Solution of water and mild soap
    ●
    Dry microfiber cleaning cloth or a chamois (static-free cloth without oil)
    ●
    Static-free cloth wipes
    CAUTION:Avoid strong cleaning solvents that can permanently damage your computer. If you are not sure
    that a cleaning product is safe for your computer, check the product contents to make sure that ingredients
    such as alcohol, acetone, ammonium chloride, methylene chloride, and hydrocarbons are not included in the
    product.
    Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and cleaning
    agents can get trapped in the scratches.
    Cleaning procedures
    Follow the procedures in this section to safely clean your computer.
