TOSHIBA computers are designed to optimize safety, minimize strain and 

withstand the rigors of portability. However, certain precautions should be 

observed to further reduce the risk of personal injury or damage to the 

computer.
Be certain to read the general precautions below and to note the cautions 

included in the text of the manual.

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 

anelectric blanket or heater.

■

Never cover or block the air vents including those located 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 serious 

injury.

Place the computer on a flat surface that is large enough for the computer 

and 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 may 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.
