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 procedures, make sure that you have turned off
the power, and disconnected all peripherals and cables (including telephone lines).
It is advisable to also remove you battery in order to prevent accidentally turning the
machine on.
