Toshiba L750D User Manual

User’s Manual

xxiii

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.
Equipment connected to the protective earthing of the building installation 

through the mains connection or through other equipment with a 

connection to protective earthing and to a cable distribution system using 

coaxial cable, may in some circumstances create a fire hazard. Connection 

to a cable distribution system has therefore to be provided through a device 

providing electrical isolation below a certain frequency range (galvanic 

isolator, see EN 60728-11).
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.
