Chassis Cover Removal and Replacement
Before removing the chassis cover to service or modify the equipment, you must disconnect all power and
modem cords (and remove the main battery in portable computers).
Replace the chassis cover and secure it with the screws before plugging in the power cable and turning it
on.
Avoid contact with the equipment during thunderstorms.
In thunderstorm conditions, make sure that you disconnect your modem from the telephone line or your
TV port from the aerial socket. A lightning strike to nearby telephone lines or an aerial could damage your
modem, TV card or even your whole computer system. Please note that the product warranty does not
apply if damage to your computer is the result of a lightning strike.
Excessive sound pressure from earphones and headphones can cause
hearing loss.
Adjustment of the equalizer to other values than the neutral or centre position may increase the earphones
and headphones output voltage and therefore the sound pressure level.
Other influencing factors relevant for the earphones/headphones output and which are specified by the
manufacturer (e.g. operating system, other equalizer software, firmware and drivers) may increase the
earphones and headphones output voltage and therefore the sound pressure level.
Heat Build-Up
The AC adapter and the underside of the computer can become hot after prolonged use. Sustained
physical contact with either should be avoided.
Glass Display
Take care when handling, cleaning transporting or storing the computer. Do not:
•
Press against, bend or twist the screen.
•
Close the lid with anything on the keyboard.
•
Transport in a container with a shard, hard object against the lid.
Any of the above actions may result in damage to the screen.
Air Circulation - System Cooling
Slots and openings in the cabinet are provided for ventilation to ensure reliable operation of the product
and to protect it from overheating. These openings should never be blocked or covered. The openings

Caution:
Storing your notebook computer in a low-airflow environment (e.g. a closed briefcase)
while it is running may damage it or cause fire.
