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 specifications, 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 current load
of all the connected devices.
• Before cleaning the computer, make sure it is disconnected from any external power sup-
plies (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.
Power Safety Warning
Before you undertake
any upgrade proce-
dures, make sure that
you have turned off the
power, and disconnect-
ed all peripherals and
cables (including tele-
phone lines). It is advis-
able to also remove your
battery in order to pre-
vent accidentally turning
the machine on.
