Instructions for Care and Operation
The notebook computer is quite rugged, but it can be damaged. To prevent this, follow these suggestions:
1. Don’t drop it, or expose it to shock. If the computer falls, the case and the components could be dam-
aged.
2. Keep it dry, and don’t overheat it. Keep the computer and power supply away from any kind of heating
element. This is an electrical appliance. If water or any other liquid gets into it, the computer could be
badly damaged.
Do not expose the computer
to any shock or vibration. Do not place it on an unstable surface. Do not place anything heavy on the computer.
Do not expose it to excessive
heat or direct sunlight. Do not leave it in a place where foreign matter or mois-
ture may affect the system.
Don’t use or store the com-
puter in a humid environment. Do not place the computer on any surface that will block the
vents.

Preface
3. Avoid interference. Keep the computer away from high capacity transformers, electric motors, and other
strong magnetic fields. These can hinder proper performance and damage your data.
4. Follow the proper working procedures for the computer. Shut the computer down properly and don’t
forget to save your work. Remember to periodically save your data as data may be lost if the battery is
depleted.
5. Take care when using peripheral devices.
Do not turn off the power
until you properly shut down
all programs.
Do not turn off any peripheral
devices when the computer is
on.
Do not disassemble the com-
puter by yourself. Perform routine maintenance on your computer.
Use only approved brands of
peripherals. Unplug the power cord before attaching peripheral devices.

Preface
Power Safety
The computer has specific power requirements:
• Only use a power adapter approved for use with this computer.
• Your AC/DC adapter may be designed for international travel but it still requires a
steady, uninterrupted power supply. If you are unsure of your local power specifi-
cations, consult your service representative or local power company.
• The power adapter may have either a 2-prong or a 3-prong grounded plug. The
third prong is an important safety feature; do not defeat its purpose. If you do not
have access to a compatible outlet, have a qualified electrician install one.
• When you want to unplug the power cord, be sure to disconnect it by the plug head,
not by its wire.
• Make sure the socket and any extension cord(s) you use can support the total cur-
rent load of all the connected devices.
• Before cleaning the computer, make sure it is disconnected from any external
power supplies (i.e. AC/DC adapter or car adapter).
Do not plug in the power
cord if you are wet. Do not use the power cord if it is broken. Do not place heavy objects on the power cord.
