Safety Precautions
The following safety precautions will increase the life of the Notebook PC. Follow all precautions and
instructions. Except as described in this manual, refer all servicing to qualied personnel.
IMPORTANT! Disconnect the AC power and remove the battery pack(s) before
cleaning. Wipe the Notebook PC using a clean cellulose sponge or chamois cloth
dampened with a solution of nonabrasive detergent and a few drops of warm water
and remove any extra moisture with a dry cloth.
DO NOT expose to or use near
liquids, rain, or moisture. DO NOT
use the modem during an electrical
storm.
DO NOT expose to dirty or dusty en-
vironments. DO NOT operate during
a gas leak.
SAFE TEMP: This Notebook PC
should only be used in environments
with ambient temperatures between
10°C (50°F) and 35°C (95°F)
Battery safety warning:
DO NOT throw the battery in re.
DO NOT short circuit the contacts.
DO NOT disassemble the battery.
DO NOT expose to strong magnetic
or electrical elds.
DO NOT place on uneven or unsta-
ble work surfaces. Seek servicing if
the casing has been damaged.
DO NOT place or drop objects on
top and do not shove any foreign
objects into the Notebook PC.
DO NOT press or touch the display
panel. Do not place together with
small items that may scratch or enter
the Notebook PC.
DO NOT leave the Notebook PC on
your lap or any part of the body in
order to prevent discomfort or injury
from heat exposure.
DO NOT carry or cover a Notebook PC that is powered ON with any materials that will
reduce air circulation such as a carrying bag.
INPUT RATING: Refer to the rat-
ing label on the bottom of the Note-
book PC and be sure that your power
adapter complies with the rating.
Introducing the Notebook PC 1
DO NOT use damaged power cords,
accessories, or other peripherals.
DO NOT use strong solvents such
as thinners, benzene, or other chemi-
cals on or near the surface.

CAUTION! There are three main types of airport security devices: X-ray machines
(used on items placed on conveyor belts), magnetic detectors (used on people
walking through security checks), and magnetic wands (hand-held devices used on
people or individual items). You can send your Notebook PC and diskettes through
airport X-ray machines. However, it is recommended that you do not send your
Notebook PC or diskettes through airport magnetic detectors or expose them to
magnetic wands.
Charge Your Batteries
If you intend to use battery power, be sure to fully charge your battery pack and any optional battery
packs before going on long trips. Remember that the power adapter charges the battery pack as long as
it is plugged into the computer and an AC power source. Be aware that it takes much longer to charge
the battery pack when the Notebook PC is in use.
Airplane Precautions
Contact your airline if you want to use the Notebook PC on the airplane. Most airlines will have
restrictions for using electronic devices. Most airlines will allow electronic use only between and not
during takeoffs and landings.
Transportation Precautions
To prepare the Notebook PC for transport, you should turn it OFF and disconnect all external pe-
ripherals to prevent damage to the connectors. The hard disk drive’s head retracts when the power
is turned OFF to prevent scratching of the hard disk surface during transport. Therefore, you should
not transport the Notebook PC while the power is still ON. Close the display panel and check that it is
latched securely in the closed position to protect the keyboard and display panel.
CAUTION! The Notebook PC’s surface is easily dulled if not properly cared for. Be
careful not to rub or scrape the Notebook PC surfaces.
Cover Your Notebook PC
Purchase a carrying bag to protect the Notebook PC from dirt, water, shock, and scratches.

to enable proper reuse of parts and recycling. The symbol of the crossed out wheeled
bin indicates that the product (electrical, electronic equipment and mercury-containing
button cell battery) should not be placed in municipal waste. Check local regulations for
disposal of electronic products.
DO NOT throw the battery in municipal waste. The symbol of the crossed out wheeled

an active matrix TFT LCD, which provides excellent viewing like that of desktop
monitors. Unlike desktop monitors, the LCD panel does not produce any radiation or
ickering, so it is easier on the eyes. Use a soft cloth without chemical liquids (use
plain water if necessary) to clean the display panel.

Central Processor Unit (CPU) Compartment
Some Notebook PC models feature a socketed-processor design to allow upgrading to
faster processors in the future. Some models feature a ULV design for compactness and
may not be upgraded. Visit an authorized service center or retailer for information on
upgrades.
WARNING! End-user removal of the CPU or hard disk drive will void the warranty.
Memory (RAM) Compartment
The memory compartment provides expansion capabilities for additional memory.
Additional memory will increase application performance by decreasing hard disk
access. The BIOS automatically detects the amount of memory in the system and
congures accordingly. There is no hardware or software (including BIOS) setup
required after the memory is installed. Visit an authorized service center or retailer for information on
memory upgrades for your Notebook PC. Only purchase expansion modules from authorized retailers
of this Notebook PC to ensure maximum compatibility and reliability.

power source and maintains power to the Notebook PC when AC power is not connected.
This allows use when moving temporarily between locations. Battery time varies by usage
and by the specications for this Notebook PC. The battery pack cannot be disassembled
and must be purchased as a single unit.
Battery Lock - Manual
The manual battery lock is used to keep the battery pack secured. Move the manual lock
to the unlocked position to insert or remove the battery pack. Move the manual lock to the
locked position after inserting the battery pack.
Battery Lock - Spring

Kensington® Lock Port
The Kensington® lock port allows the Notebook PC to be secured using Kensington®
compatible Notebook PC security products. These security products usually include
a metal cable and lock that prevent the Notebook PC to be removed from a
xed object. Some may also include a motion detector to sound an alarm when
moved.

USB Port (2.0/1.1)
The USB (Universal Serial Bus) port is compatible with USB 2.0 or USB 1.1 devices such
as keyboards, pointing devices, cameras, hard disk drives, printers, and scanners connected
in a series up to 12Mbits/sec (USB 1.1) and 480Mbits/sec (USB 2.0). USB allows many
devices to run simultaneously on a single computer, with some peripherals acting as additional plug-in
sites or hubs. USB supports hot-swapping of devices so that most peripherals can be connected or
disconnected without restarting the computer.
Air Vents
The air vents allow cool air to enter and warm air to exit the Notebook PC.
IMPORTANT! Ensure that paper, books, clothing, cables, or other objects
do not block any of the air vents or else overheating may occur.

a standard Ethernet cable for connection to a local network. The built-in connector al-
lows convenient use without additional adapters.
HDMI Port
HDMI (High-Denition Multimedia Interface) is an uncompressed all-digital
audio/video interface between any audio/video source, such as a set-top box, DVD
player, and A/V receiver and an audio and/or video monitor, such as a digital tel-
evision (DTV). Supports standard, enhanced, or high-denition video, plus multi-
channel digital audio on a single cable. It transmits all ATSC HDTV standards and
supports 8-channel digital audio, with bandwidth to spare to accommodate future
enhancements or requirements.
HDMI
2.0
USB Port (2.0/1.1)
The USB (Universal Serial Bus) port is compatible with USB 2.0 or USB 1.1 devices such as key-
boards, pointing devices, cameras, hard disk drives, printers, and scanners connected in a series up to
12Mbits/sec (USB 1.1) and 480Mbits/sec (USB 2.0). USB allows many devices to run simultaneously
on a single computer, with some peripherals acting as additional plug-in sites or hubs. USB supports
hot-swapping of devices so that most peripherals can be connected or disconnected without restarting
the computer.
