    							Webcam
    Your computer includes an integrated webcam, located at the top of the display. The webcam allows
    you to capture and share video.
    NOTE:Your computer may look slightly different from the illustration in this section.
    To use the webcam:
    ▲Double-tap the HP TouchSmart icon or the MediaSmart icon on the desktop, and then do one of
    the following:
    ●Tap the video icon (1) on the screen.
    A window opens that displays a Webcam button.
    ●Tap the Webcam button.
    NOTE:In the video module, you can start the webcam, create a video, and upload your
    video to YouTube.
    – or –
    ▲Tap the small Webcam icon (2) at the bottom of the screen.

    							For optimum performance, observe the following guidelines while using the webcam:
    ●If you are having trouble viewing or sending multimedia files to someone on another LAN or outside
    your network firewall, temporarily disable the firewall, perform the task you want to perform, and
    then reenable the firewall. To permanently resolve the problem, reconfigure the firewall as
    necessary, and adjust the policies and settings.
    ●Whenever possible, place bright light sources behind the camera and out of the picture area.
    Adjusting webcam properties
    You can adjust webcam properties using the Properties dialog box, which is accessible from various
    programs that use the integrated camera, usually from a configuration, settings, or properties menu:
    ●Brightness—Controls the amount of light that is incorporated into the image. A higher brightness
    setting creates a brighter image; a lower brightness setting creates a darker image.
    ●Contrast—Controls the difference between lighter and darker areas on the image. A higher
    contrast setting intensifies the image; a lower contrast setting maintains more of the original
    information’s dynamic range but leads to a flatter image.
    ●Hue—Controls the aspect of color that distinguishes it from another color (what makes a color red,
    green, or blue). Hue is distinct from saturation, which measures the intensity of the hue.
    ●Saturation—Controls the strength of color in the final image. A higher saturation setting creates a
    bolder image; a lower saturation setting creates a more subtle image.
    ●Sharpness—Controls the definition of edges in an image. A higher sharpness setting creates a
    more defined image; a lower sharpness setting creates a softer image.
    ●Gamma—Controls the contrast affecting the mid-level grays or midtones of an image. Adjusting
    the gamma of an image allows you to change the brightness values of the middle range of gray
    tones without dramatically altering the shadows and highlights. A lower gamma setting makes
    grays look black, and makes dark colors even darker.
    ●Backlight Comp—Compensates in cases where a subject with a large amount of background light
    would otherwise be obscured by blooming or silhouetting.
    For information about using the webcam, select Start > Help and Support.

    NOTE:If the tray is not fully accessible, tilt the disc carefully as you remove it.
    4.Close the disc tray and place the disc in a protective case.
    The computer does not detect the optical drive
    If Windows does not detect an installed device, the device driver software may be missing or corrupted.
    If you suspect that the optical drive is not being detected, verify that the optical drive is listed in the
    Device Manager utility.
    1.Remove any discs from the optical drive.
    2.Select Start > Control Panel > System and Security. Then in the System area, click Device
    Manager.

    							5 Power management
    Setting power options
    Using power-saving states
    The computer has two power-saving states enabled at the factory: Sleep and Hibernation.
    When Sleep is initiated, the power lights blink and the screen clears. Your work is saved to memory,
    letting you exit Sleep faster than exiting Hibernation. If the computer is in the Sleep state for an extended
    period or if the battery reaches a critical battery level while in the Sleep state, the computer initiates
    Hibernation.
    When Hibernation is initiated, your work is saved to a hibernation file on the hard drive and the computer
    turns off.
    CAUTION:To prevent possible audio and video degradation, loss of audio or video playback
    functionality, or loss of information, do not initiate Sleep or Hibernation 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.
    Initiating and exiting Sleep
    The system is set at the factory to initiate Sleep after 15 minutes of inactivity when running on battery
    power and 30 minutes of inactivity when running on external power.
    Power settings and timeouts can be changed using Power Options in Windows® Control Panel.
    With the computer on, you can initiate Sleep in any of the following ways:
    ●Press fn+f5.
    ●Briefly press the power button.
    ●Close the display.
