    							7 Managing and sharing information
    Drives are digital storage devices or solid-state drives that help you store, manage, share, and
    access information. Your computer has an internal hard drive that stores your computers software,
    operating system, as well as providing storage for all of your personal files. Some computers also
    have a built-in optical drive that allows you to read or write to a CD, DVD, or (on select models) Blu-
    ray Disc (BD), to play and record audio and video.
    For added capacity or functionality, connect an external drive (purchased separately), such as an
    optical drive or hard drive, or insert a digital storage card to import information directly from your
    phone or camera. A USB flash drive, connected to the Universal Serial Bus (USB) port on your
    computer, also allows quick data transfer. Some devices use the computers power to run; others
    have their own power source. Some devices come with software that must be installed.
    NOTE:For information about connecting external wireless devices, see Connecting to a network
    on page 15.
    NOTE:For more information about required software and drivers, or to learn which computer port to

    							Using optical drives
    An optical disc drive uses laser light to read or store large amounts of information. Some drives can
    only read information, but others can also write (burn) information onto a blank disc.
    Use these tips for best performance of your optical drive:
    ●When the battery is the only source of power, be sure the battery is sufficiently charged before
    writing to media.
    ●Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The
    write process is sensitive to vibration.
    ●Make sure you have installed the latest software updates for the drive.
    ●If the disc you are using is not clean, wipe it with a dry, lint-free, soft cloth.
    Your computer may include an optical drive that supports one or more of the following disc
    technologies:
    ●CD—A compact disc stores data that is read by a laser from the optical disc drive. The following
    CD formats are available:
    ◦CD-Recordable (CD-R), which allows the computer to read information and to record
    information one time on the CD. Once the information is recorded on the CD-R disc, it
    cannot be changed or erased; it is permanent.
    ◦CD-Re-Writable (CD-RW), which allows you to read information and record information
    many times to the CD. Information on the CD can be erased.
    ●DVD—A digital video disc is a high-capacity optical disc. It can store more information than a
    CD. A double-sided DVD can store up to 17 GB. The following DVD formats are available:
    ◦DVD-Recordable (DVD-R or DVD+R), which allow the computer to read information and to
    record information one time on the DVD. After the information is recorded on the disc, it
    cannot be changed or erased; it is permanent. The DVDs can be used in DVD±R drives.
    ◦DVD-Re-Writable (DVD-RW or DVD+RW), which allow to read information and record
    information many times to the disc. Information on the disc can be erased. The DVDs can
    be used in DVD±R drives.
    ●BD—a Blu-ray Disc holds more information than the other optical discs and they can used to
    record, rewrite, and play back high-definition (HD) video.
    Note the following when using BDs:
    ●CyberLink PowerDVD is installed on the computer to play BD movies.
    ●Playing most BD movie titles on an external display requires an HDMI digital connection. The
    computer can support up to 1080p resolution on an external display, which requires a 1080p-
    capable HDTV or monitor.
    ●Attempting to play a BD movie simultaneously on both the internal and an external display may
    cause an error, so choose only one.
    ●For copy protection purposes, Advanced Access Content System (AACS) keys are integrated
    into the computer. AACS keys require occasional renewal to support playback of new BD movie
    releases. The CyberLink PowerDVD program will request an update to continue playback when
    Using optical drives 49 
    						
    							such a BD movie release is inserted in the drive. Follow the on-screen instructions to install the
    update.
    ●If lines appear on the display when viewing a BD, they may be caused by interference from the
    wireless network. To resolve the issue, close any open applications and turn off your wireless
    feature.
    Inserting an optical disc
    1.Turn on the computer.
    2.Press the release button (1) on the drive bezel to release the disc tray.
    3.Pull out the tray (2).
    4.Hold the disc by the edges to avoid touching the flat surfaces and position the disc label-side up
