Before you connect the computer to a power source, ensure that the
voltage rating of the AC adapter matches that of the available power
source:
115 V/60 Hz in most of North and South America and some Far
Eastern countries such as South Korea and Taiwan
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
230 V/50 Hz in most of Europe, the Middle East, and the Far East
To help prevent electric shock, plug the AC adapter and external
device power cables into properly grounded power sources. These
cables are equipped with 3-prong plugs to help ensure proper
grounding. Do not use adapter plugs or remove the grounding prong
from a cable. If you must use an extension cable, use a 3-wire cable
with properly grounded plugs.
If you use an extension cable with your AC adapter, ensure that the
total ampere rating of the products plugged in to the extension cable
does not exceed the ampere rating of the extension cable.
To remove power from the computer, turn it off, remove the battery,
and disconnect the AC adapter from the electrical outlet.
If your computer includes an integrated or optional (PC Card)
modem, disconnect the modem cable during an electrical storm to
avoid the remote risk of electric shock from lightning via the telephone
line.
To help avoid the potential hazard of electric shock, do not connect or
disconnect any cables or perform maintenance or reconfiguration of
this product during an electrical storm.
PC Cards may become very warm during normal operation. Use care
when removing PC Cards after their continuous operation.
Do not dispose of batteries in a fire. They may explode. Check with
local authorities for disposal instructions.
When setting up the computer for work, place it on a level surface.
When traveling, do not check the computer as baggage. You can put
your computer through an X-ray security machine, but never put your
computer through a metal detector. If you have the computer checked
by hand, be sure to have a charged battery available in case you are
asked to turn on the computer.
