Warning
Before you undertake
any upgrade proce-
dures, make sure that
you have turned off the
power, and discon-
nected all peripherals
and cables (including
telephone lines). It is
advisable to also re-
move your battery in
order to prevent acci-
dentally turning
machine on.
VI
• 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).
