							ENERGY STAR®
 ProgramYour Computer model may be ENERGY STAR ®
compliant. If the model you purchased is compliant, it uses
the Energy Star logo and the following information applies.
TOSHIBA is a partner in the ENERGY STAR Program and
has designed this computer to meet the latest ENERGY
STAR guidelines for energy efficiency. Your computer
ships with the power management options preset to a
configuration that will provide the most stable operating
environment and optimum system performance for both
AC power and battery modes.
To conserve energy, your computer is set to enter the low-
power Sleep Mode which shuts down the system and
display within 15 minutes of inactivity in AC power mode.
TOSHIBA recommends that you leave this and other
energy saving features active, so that your computer will operate at its maximum energy efficiency. You can wake
the computer from Sleep Mode by pressing the power
button.
Your ENERGY STAR certified computer should be set by default to enter a low-power "sleep mode" after a period of
inactivity. Simply touching the mouse or keyboard "wakes" the computer in seconds. These sleep features can save
you up to $23 per year (200 kWh per year in electricity) and prevent up to 300 pounds of greenhouse gas
emissions annually.To learn how to adjust or activate
these sleep settings on your computer, please go to:
www.energystar.gov/sleepinstructions
To activate sleep settings organization-wide quickly and
easily through network tools, please go to
www.energystar.gov/powermanagement
Disposing of the computer and the computer's
batteries The computer's battery pack is not user-accessible. Contact an authorized
TOSHIBA service provider for details regarding how to dispose of the computer and the battery pack.

							Provide adequate ventilationAlways make sure that 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 at the base 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.
Always provide sufficient space around the computer.
Overheating your computer or AC adaptor could cause system failure, computer or AC adaptor damage or a fire, possibly resulting in seriousinjury.
Creating a computer-friendly environment Place the computer on a flat surface that is large enough for the computerand any other items you are using, such as a printer.
Leave enough space around the computer and other equipment to provide
adequate ventilation. Otherwise, they might overheat.
To keep your computer in prime operating condition, protect your work area
from:
Dust, moisture, and direct sunlight.
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.
Stress injury Carefully read the  Instruction Manual for Safety and Comfort . It contains
information on the prevention of stress injuries to your hands and wrists that can be caused by extensive keyboard use. It also includes information
on work space design, posture, and lighting that can help reduce physical
stress.

							Heat injury
Avoid prolonged physical contact with the computer. If the computer isused for long periods, its surface can become very warm. While the temperature will not feel hot to the touch, if you maintain physical
contact with the computer for a long time, for example if you rest the computer on your lap or if you keep your hands on the palm rest, your
skin might suffer a low-heat injury.
If the computer has been used for a long time, avoid direct contact
with the metal plate supporting the various interface ports as this can become hot.
The surface of the AC adaptor can become hot when in use but this
condition does not indicate a malfunction. If you need to transport the
AC adaptor, disconnect it and let it cool before moving it.
Do not lay the AC adaptor on a material that is sensitive to heat as thematerial could become damaged.
Pressure or impact damage Do not apply heavy pressure to the computer or subject it to any form of
strong impact as this can damage the computer's components or otherwise
cause it to malfunction.
Cleaning the computer To help ensure long, trouble-free operation, keep the computer free of dustand dirt, and use care with all liquids around it.
Be careful not to spill liquids into the computer. If the computer does
get wet, turn the power off immediately and let the computer dry
completely. In these circumstances, you should get the computer
inspected by an authorized service provider in order to assess the
scope of any damage.
Clean the plastics of the computer using a cloth slightly dampened
with water.
You can clean the display screen by spraying a small amount of glass
cleaner onto a soft, clean cloth and then wiping the screen gently with the cloth.
Never spray cleaner directly onto the computer or let liquid run into any part
of it. Never use harsh or caustic chemical products to clean the computer.

example, in a situation where you carry the computer from a cold
environment to a warm room). Do not turn on the power until
condensation disappears.
Be careful not to subject the computer to impact or shock. A failure to
follow this instruction could result in damage to computer, computer failure, or loss of data.

							chance of developing a painful or disabling injury to your hand, arms,shoulders, or neck.
This section provides basic information to start using your computer. Itcovers the following topics:
Connecting the AC adaptor
Opening the display
Turning on the power
Initial setup
Use a virus-check program and make sure that it is updated regularly.
Never format storage media without checking its content - formatting
destroys all stored data.
It is a good idea to back up the internal Hard Disk Drive or other main
storage device to external media periodically. General storage media is not durable or stable over long periods of time and under certain conditions might result in data loss.
Before you install a device or application, save any data in memory to
the Hard Disk Drive or other storage media. Failure to do so might
result in data loss.
Connecting the AC adaptor
Attach the AC adaptor when you want to charge the battery or operate fromAC power. The battery pack must be charged before you can operate from
battery power.
The AC adaptor can automatically adjust to any voltage ranging from 100
volts to 240 volts and to a frequency of either 50 hertz or 60 hertz, enabling you to use this computer in almost any country/region. The adaptor
converts AC power to DC power and reduces the voltage supplied to this
computer.
Always use the TOSHIBA AC adaptor that was included 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.
Never plug the AC adaptor into a power source that does notcorrespond to both the voltage and the frequency specified on the regulatory label of the unit. Failure to do so could result in a fire orelectric shock, possibly resulting in serious injury.
