Stress injury
Carefully read the Instruction Manual for Safety and Comfort. It contains
information on prevention of stress injuries to your hands and wrists that
can be caused by extensive keyboard use. Chapter 3, Getting Started , also
includes information on work space design, posture and lighting that can
help reduce physical stress.
Heat injury
■ Avoid prolonged physical contact with the bottom of 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, 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 adapter can become hot when in use. This
condition does not indicate a malfunction. If you need to transport the
AC adapter, disconnect it and let it cool before moving it.
■ Do not lay the AC adapter 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 damage computer components or
otherwise cause malfunctions.
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 phones
Use of mobile phones can interfere with the audio system. Computer
operation is not impaired but it is recommended that a distance of 30 cm be
maintained between the computer and a mobile phone in use.
LCD
Over a period of time, and depending on the usage of the computer, the
brightness of the LCD screen will deteriorate. This is an intrinsic
characteristic of LCD technology. Maximum brightness is only available
when operating in AC power mode. The screen will dim when the computer
is operated on battery power and you may not be able to increase the
brightness of the screen.
