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.

Reconnect the cables.
