    							6 Managing power
    Your computer can operate on either battery power or external power. When the computer is running
    on battery power only and an AC power source is not available to charge the battery, it is important to
    monitor and conserve the battery charge. Your computer supports an optimal power plan to manage
    how your computer uses and conserves power so that computer performance is balanced with power
    conservation.
    Initiating Sleep and Hibernation
    Microsoft® Windows has two power-saving states, Sleep and Hibernation.
    ●Sleep—The Sleep state is automatically initiated after a period of inactivity when running on
    battery power or on external power. Your work is saved to memory, allowing you to resume your
    work very quickly. You can also initiate Sleep manually. For more information, see 
    Manually
    initiating and exiting Sleep on page 34.
    ●Hibernation—The Hibernation state is automatically initiated if the battery reaches a critical level.
    In the Hibernation state, your work is saved to a hibernation file and the computer powers down.
    NOTE:You can manually initiate Hibernation. See Manually initiating and exiting Sleep
    on page 34 and Manually initiating and exiting Hibernation (select models only) on page 34.
    CAUTION:To reduce the risk of possible audio and video degradation, loss of audio or video
    playback functionality, or loss of information, do not initiate Sleep while reading from or writing to a
    disc or an external media card.
    NOTE:You cannot initiate any type of networking connection or perform any computer functions
    while the computer is in the Sleep state or in Hibernation.

    							7 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. It also provides information about updating your
    programs and drivers, instructions for cleaning your computer, and tips for traveling with your
    computer.
    Improving performance
    Everyone wants a fast computer and you can drastically improve the performance of your computer
    by performing regular maintenance tasks with tools such as Disk Defragmenter and Disk Cleanup.
    Also, as your computer gets older, you might consider installing larger drives and adding more
    memory.
    Using HP 3D DriveGuard (select models 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:Because solid state drives (SSDs) lack moving parts, they do not require HP 3D DriveGuard
    protection.
    NOTE:A hard drive in a primary hard drive bay or a secondary hard drive bay is 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.
    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 models 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, or in the Mobility Center.
    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.
    40 Chapter 7   Maintaining your computer 
    						
    							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.From the Start screen, type disk.
    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.From the Start screen, type disk, and then select Uninstall apps to free up disk space.
    2.Follow the on-screen instructions.
    Updating programs and drivers
    HP recommends that you update your programs and drivers on a regular basis to the latest versions.
    Updates can resolve issues and bring new features and options to your computer. Technology is
    always changing, and updating programs and drivers allows your computer to run the latest
    technology available. 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 update notifications when they become available.
