    Selecting a place to work
    ❖Equipment that generates a strong electromagnetic field, 
    such as stereo speakers (other than speakers that are 
    connected to the computer) or speakerphones.
    ❖Rapid changes in temperature or humidity and sources 
    of temperature change such as air conditioner vents or 
    heaters.
    ❖Extreme heat, cold, or humidity.
    ❖Liquids and corrosive chemicals.
    Keeping yourself comfortable
    This section provides information for setting up your work 
    environment and tips for working comfortably throughout the 
    day.
    Computer user comfort recommendations
    Good Working Posture
    ❖Adjust your chair height: your feet should be flat on the 
    floor and the bottom of your thighs should be evenly 
    supported by the seat. If your feet cannot reach the floor, 
    use a foot rest. Avoid pressure points behind the knee or 
    under the thigh.
    ❖The space under your desk should be free of clutter so 
    that your legs and feet are not restricted, and you can 
    get close enough to your notebook and other items that 
    you use frequently.
    ❖Adjust the chair back rest: it should match the curve of 
    your back and provide comfortable back support.
    ❖Adjust the chair arm rests: they should be about the 
    same height as the keyboard and comfortably support 
    your arms, allowing your shoulders to relax.
    ❖When using the keyboard, it should be centered in front 
    of you.
    ❖The keyboard and pointing device should be close to 
    your elbow level. The keyboard should be flat so that 
    your wrists are straight when typing. However, if the 
    notebook is on a work surface that is above your elbow 
    height you may need to slope the notebook to keep your 
    wrists straight.
    ❖Work with relaxed shoulders. 
    						
    							32Getting Started
    Selecting a place to work
    ❖When typing, keep your wrists straight and try not to rest 
    your wrists on the notebook. Support your arms on your 
    forearm area. The forearms can be supported by the 
    chair arm supports or the desk surface.
    ❖The notebook display should be tilted so that the image 
    on the screen is clear. 
    ❖Avoid glare: position the notebook so that light sources 
    (lamps or windows) do not shine or reflect directly into 
    your eyes. Place the notebook display away from bright 
    light sources or reduce the light intensity from windows 
    by using blinds. Glare on the notebook display may 
    cause eye strain, eye fatigue or headaches.
    ❖Certain notebook displays have a brightness 
    approaching that of a TV device. We recommend that 
    you adjust the brightness of your notebook display to a 
    comfortable level to prevent possible eye strain.
    ❖Keep your head level, facing forward and balanced over 
    your torso.
    ❖Adjust the font size of text on your screen to make 
    viewing comfortable.
    ❖Rest your eyes periodically by focusing on objects that 
    are farther away.

    							33Getting Started
    Selecting a place to work
    ❖When using a notebook for long hours, it may be more 
    comfortable to dock the notebook and use an external 
    keyboard, mouse and monitor.
    ❖The keyboard and mouse (or trackball) should be close 
    to your elbow level.
    ❖The mouse should be next to the keyboard to avoid a 
    reach. If you have to reach, the arm should be supported 
    in the forearm area by the desk surface or the chair arm 
    supports.
    ❖Alternative keyboards, such as the split curved 
    keyboard, may improve shoulder and arm comfort.
    ❖Select a mouse that is comfortable for you to use.
    ❖Don’t rest your wrists on the edge of the keyboard or on 
    the work surface when typing.
    ❖The monitor should be about an arm length away while 
    sitting back in the chair.
    ❖The monitor should be centered in front of your body.
    ❖The top of the monitor should be at or slightly below eye 
    level. A monitor that is too high or too low can cause 
    awkward head and neck postures and may lead to 
    discomfort in the neck muscles.
    ❖If you use bifocals you may need to lower the monitor. 
    Alternatively, you might consider customized 
    prescription computer glasses.
    Ty p i n g  s t y l e
    ❖Learn to touch type so that you don’t have to look down 
    at the keyboard.
    ❖Type with straight wrists.
    ❖Type lightly.
    ❖Learn the keyboard shortcuts for your applications. You 
    will be more productive.
    ❖Use the pointing device (e.g., touch pad, Accupoint
    ®, or 
    tablet pen whichever is available with your notebook 
    computer, or other optional pointing devices like mouse 
    or trackball) with a comfortable hand posture. Avoid 
    awkward hand postures or high gripping force.
    ❖It is helpful to change the type of pointing device that 
    you use on a regular basis to avoid working in just one 
    hand posture. 
    						
    							34Getting Started
    Selecting a place to work
    Taking breaks and varying tasks
    ❖Change the way you work so that you are not stuck in 
    the same posture for long periods of time. Some people 
    find it comfortable to occasionally stand while using the 
    notebook. To do this properly, the notebook needs to be 
    on an elevated surface. Make sure you follow the Good 
    Working Posture points mentioned above while working.
    ❖Take short, strategically spaced rest breaks to avoid eye 
    strain and body fatigue. For example, stand up and walk 
    around or stretch for a few minutes every hour.
    ❖Taking regular breaks is especially important if you are 
    working long hours on your computer or working on a 
    deadline.
    ❖If stress at work is affecting your health, try to identify 
    the sources of the stress and evaluate ways to reduce 
    the stress.
    Mobile computing tips
    ❖When using the notebook at airports, on airplanes or 
    trains, or at meetings, make sure that you take the time 
    to consider the points just mentioned.
    ❖When working on the road it may be difficult to set up 
    the notebook in an optimal position. In these situations it 
    is important that you take frequent breaks and change 
    your posture frequently to relieve the excess loads on 
    your body.
    ❖Be creative, when in a hotel room, use a rolled up 
    blanket or pillows to provide back support, or to provide 
    arm support. To position the computer at a good height, 
    remember to operate the computer on a hard flat stable 
    surface. Using your computer on a carpet, blanket or 
    other soft materials can block the air vents including 
    those located at the base of the computer and possibly 
    cause overheating of your computer.
    Transporting the notebook
    Although your notebook is light, carrying it for a long time 
    may lead to shoulder and arm fatigue. If you carry your 
    notebook with other items, consider using an ergonomically-
    designed computer case.

    Selecting a place to work
    Seeking additional help
    Follow the advice from your employer’s company health and 
    safety staff. Contact them if you need assistance making 
    adjustment to your workstation or adjusting the lighting.
    Again, if you experience persistent or recurrent pain, ache, 
    numbness, burning, or stiffness you should promptly see a 
    qualified health care provider. These sensations may be 
    caused by serious medical conditions that can be treated.

    Precautions
    Your computer is designed to provide optimum safety and 
    ease of use, and to withstand the rigors of travel. You should 
    observe certain precautions to further reduce the risk of 
    personal injury or damage to the computer. 
    ❖Avoid prolonged physical contact with the underside or 
    surface of the computer. 
    Never allow any liquids to spill into any part of your 
    computer, and never expose the computer to rain, water, 
    seawater or moisture. Exposure to liquid or moisture can 
    cause electric shock or fire, resulting in damage or 
    serious injury. If any of these eventualities should 
    accidentally occur, immediately:
    1. Turn off the computer.
    2. Disconnect the AC adaptor from the power plug 
    socket and computer.
    3. Remove the battery pack, if applicable.
    Failure to follow these instructions could result in serious 
    injury or permanent damage to the computer.
    Do not turn on the power again until you have taken the 
    computer to an authorized service center.
    ❖Avoid prolonged physical contact with the underside 
    or surface of the computer.
    ❖Computer base and palm rest can become hot! Avoid 
    prolonged contact to prevent heat injury to skin.
    Today’s performance computers generate heat under normal 
    operating conditions, as a function of system activity. Avoid 
    extended contact between the computer base or palm rest 
    and your skin. Under certain operating conditions such 
    prolonged contact between the computer base or palm rest 
    and your skin may result in skin irritation and/or heat injury. 
    						
    							37Getting Started
    Selecting a place to work
    Consider using a hard computer insulating pad or similarly 
    suitable hard insulating material when using a computer on 
    your lap.
    Never place a heavy object on the computer and be 
    careful not to drop a heavy object onto the computer. It 
    could damage the computer or cause system failure.
    ❖Never turn off the computer if a drive light indicates a 
    drive is active.
    Turning off the computer while it is reading from or 
    writing to a disk/disc or flash media may damage the 
    disk/disc or flash media, the drive, or both.
    ❖Keep the computer and disks away from objects that 
    generate strong magnetic fields, such as large stereo 
    speakers.
    Information on some disks is stored magnetically. 
    Placing a magnet too close to a disk can erase important 
    files.
    Handle discs carefully. Avoid touching the surface of the 
    disc. Grasp it by its center hole and edge. If you handle 
    the disc incorrectly, you could damage the disc and 
    possibly lose data.
    ❖Scan all new files for viruses.
    This precaution is especially important for files you 
    receive via email or download from the Internet. 
    Occasionally, even new programs you buy from a 
    supplier may contain a computer virus. You need a 
    special program to check for viruses.

    Setting up your computer
    Important information on your computer’s 
    cooling fan
    Your computer may have a CPU cooling fan that cools the 
    CPU by drawing outside air into the computer.
    Always make sure your computer and AC adaptor have 
    adequate ventilation and are protected from 
    overheating when the power is turned on or when an 
    AC adaptor is connected to a power outlet (even if your 
    computer is in Sleep mode). In this condition, observe 
    the following:
    ❖Never cover your computer or AC adaptor with 
    any object.
    ❖Never place your computer or AC adaptor near a 
    heat source, such as an electric blanket or heater.
    ❖Never cover or block the air vents including those 
    located at the underside of the computer.
    ❖Always operate your computer on a hard flat 
    surface. Using your computer on a carpet or other 
    soft material can block the vents located at the 
    underside of the computer.
    Overheating your computer or AC adaptor could cause 
    system failure, computer or AC adaptor damage or a fire, 
    possibly resulting in serious injury.
    The cooling fan location will vary depending on the 
    computer.
    Setting up your computer
    TECHNICAL NOTE: You must complete all setup steps 
    up to and including “Setting up your software” on 
    page 42 before adding external or internal components 
    to your computer. These components include, but are 
    not limited to, a mouse, keyboard, and printer.
    Your computer contains a rechargeable main battery that 
    needs to be charged before you can use it.
    To use external power or to charge the battery you must 
    attach the AC adaptor. See “Connecting to a power source” 
    on page 39. 
    NOTE 
    						
    							39Getting Started
    Connecting to a power source
    Please handle your computer carefully to avoid 
    scratching or damaging the surface.
    Connecting to a power source
    Your computer requires power to operate. Use the power 
    cord/cable and AC adaptor to connect the computer to a live 
    electrical outlet, or to charge the computer’s battery. 
    Never pull on a power cord/cable to remove a plug from 
    a socket. Always grasp the plug directly. Failure to follow 
    this instruction may damage the cord/cable, and/or result 
    in a fire or electric shock, possibly resulting in serious 
    injury.
    Always confirm that the power plug (and extension cable 
    plug if used) has been fully inserted into the socket, to 
    ensure a secure electrical connection. Failure to do so 
    may result in a fire or electric shock, possibly resulting in 
    serious injury.
    Be careful if you use a multiple connector. An overload on 
    one socket could cause a fire or electric shock, possibly 
    resulting in serious injury.
    Always use the TOSHIBA AC adaptor that was provided 
    with your computer, or use AC adaptors specified by 
    TOSHIBA to avoid any risk of fire or other damage to the 
    computer. Use of an incompatible AC adaptor could 
    cause fire or damage to the computer possibly resulting 
    in serious injury. TOSHIBA assumes no liability for any 
    damage caused by use of an incompatible adaptor.
    To connect AC power to the computer:
    1Connect the power cord/cable to the AC adaptor.
    Handling the cord on this product will expose you to 
    lead, a chemical known to the State of California to 
    cause birth defects or other reproductive harm. 
    Wash hands after handling.
    NOTE 
    						
    							40Getting Started
    Charging the main battery
    2Plug the AC adaptor cord into the DC-IN on the side of 
    the computer.
    To locate your DC-IN port, please refer to your Quick 
    Start document.
    3Connect the power cord/cable to a live electrical outlet.
    The AC power light on the indicator panel glows white.
    Never attempt to connect or disconnect a power plug 
    with wet hands. Failure to follow this instruction could 
    result in an electric shock, possibly resulting in serious 
    injury.
    The computer’s main battery light gives you an 
    indication of the main battery’s current charge:
    ❖Glows amber while the main battery is being charged 
    (AC adaptor connected)
    ❖Glows white when the main battery is fully charged
    ❖Is unlit when the main battery has discharged, the 
    battery is not charging, or the AC adaptor is not 
    plugged into the computer or AC outlet
    ❖Flashes amber when the main battery charge is low 
    and it is time to recharge the main battery or plug in 
    the AC adaptor
    If the AC power light flashes amber during charging, 
    either the main battery is malfunctioning, or it is not 
    receiving correct input from the AC power supply.
    Charging the main battery
    Before using the battery to power the computer, you must 
    charge the battery.
    To charge the battery, leave the computer plugged into an 
    AC power source with the computer turned off until the 
    battery light glows white. After that, the battery will be 
    completely charged and ready to power the computer.
