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 
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 
located at the base 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.

Read the “Provide adequate ventilation” section in the “Instruction 
Manual for Safety and Comfort” that is shipped with your 
computer.

The cooling fan location will vary depending on the computer.

TECHNICAL NOTE: You must complete all setup steps up to and 
including 

 before adding 

external or internal components to your computer. These 
components include, but are not limited to, a mouse, keyboard, 
printer, memory, and ExpressCards
