    							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 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 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 is protected by HP 3D DriveGuard. A hard drive
    installed in an optional docking devices 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
    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:
    ●
    If the software is actively protecting the drive, a green check mark 
     is superimposed over the
    icon.
    ●
    If the software has been disabled, a no symbol 
     is superimposed over the icon.
    ●
    If the software has parked the drive due to a shock event, an orange cone 
     is superimposed
    over the icon.
    48 Chapter 7   Maintaining your computer 
    						
    							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.From the Start screen, type d, and then type disk in the search box. Select Settings, 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
    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 d, and then type disk in the search box. Select Settings, and then
    select Free up disk space by deleting unnecessary files.
    2.Follow the on-screen instructions.
    Improving performance 49 
    						
    							Adding or replacing memory modules
    Adding memory can help improve your computers 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.
    NOTE:If you are adding or replacing the memory module in your computer with a single memory
    module, insert the memory module into the slot further away from the system board.
    NOTE:To use a dual-channel configuration with a second memory module, be sure that both
    memory modules are identical.
    To add or replace a memory module:
    CAUTION:To prevent information loss or an unresponsive system:
    Shut down the computer before adding or replacing memory modules. Do not remove a memory
    module while the computer is on, in the Sleep state, on in Hibernation.
    If you are not sure whether the computer is off or in Hibernation, turn the computer on by pressing the
    power button. Then shut down the computer 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 (see 
    Removing a user-replaceable battery on page 42).
    6.Remove the service door from the computer.
    7.If you are replacing a memory module, remove the existing memory module:
    a.Pull away the retention clips (1) on each side of the memory module.
    The memory module tilts up.
