Stress injury
Carefully read the Instruction Manual for Safety & Comfort. It contains
information on prevention of stress injuries to your hands and wrists than
can be caused by extensive keyboard use. Chapter 3, Getting Started, also
includes information on workspace design, posture and lighting that can
help reduce physical stress.
Heat injury
■Avoid prolonged physical contact with the computer. If the computer is
used 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 (if you rest the computer on
your lap, or if you keep your hands on the palm rest, for example) your
skin might suffer low-heat injury.
■If the computer has been used for a long time, avoid direct contact with
the metal plate supporting the I/O ports. It can become hot.
■The surface of the AC adaptor can become hot when in use. 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. The
material could be damaged.
Pressure or impact damage
Do not apply heavy pressure to the computer or subject it to strong impact.
Excessive pressure or impact can cause damage to computer components
or otherwise cause malfunctions.

General Precautions
PC card overheating
Some PC cards can become hot with prolonged use. Overheating of a PC
card can result in errors or instability in the PC card operation. Also be
careful when you remove a PC card that has been used for a long time.
Mobile phone
Use of mobile phones can interfere with the audio system. Computer
operation is not impaired but is recommended that a distance of 30 cm be
maintained between the computer and a mobile phone in use.
Cooling
1. Cleaning of dust accumulated on the cooling vent of the computer.
2. Cooling vents on the underside and back side of the computer.
When you use your computer in a dusty area, dirt and debris may
accumulate on the cooling vents at the under side of your unit. If this
occurs, the accumulated dust can cause insufficient heat dissipation which
may result in the computer shutting down during use. Carefully clean the
dust from the vents using a vacuum cleaner.

Cooling vents
Cooling vents
To prevent possible overheating of the CPU, make sure the cooling fan’s
air intake is not blocked. The fan draws in air by creating a vacuum. If the
fan is blocked, it could cause the CPU to run at a lower performance level
or cause the computer to shut down. Loose items such as notebook and
tissue paper, plastic wrappers, or other similar materials can block the air
intake, preventing air from reaching the CPU. Do not use the computer on
surfaces with objects that can be drawn in by the cooling fan.
