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

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.

1 Introducing the Notebook PC
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.
DO NOT throw the Notebook PC in municipal waste. This product has been designed
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
bin indicates that the battery should not be placed in municipal waste.

The display panel functions the same as a desktop monitor. The Notebook PC uses
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.

Knowing the Parts 2
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.

Hard Disk Drive Compartments
The hard disk drive is secured in a compartment. Visit an authorized service center or
retailer for information on hard disk drive upgrades for your Notebook PC. Only purchase
hard disk drives from authorized retailers of this Notebook PC to ensure maximum compat-
ibility and reliability.
2
3Battery Pack
The battery pack is automatically charged when the Notebook PC is connected to an AC
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 - Spring
The spring battery lock is used to keep the battery pack secured. When the battery pack is inserted, it will
automatically lock. To remove the battery pack, this spring lock must be held in the unlocked position.

book PC’s optical drive may support compact discs (CD) and/or digital video discs
(DVD) and may have recordable (R) or re-writable (RW) capabilities. See the market-
ing specications for details on each model.

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 al-
lows many devices to run simultaneously on a single computer, with some peripherals act-
ing 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.

USB Port (2.0/1.1)
Display (Monitor) Output
The 15-pin D-sub monitor port supports a standard VGA-compatible device such as a moni-
tor or projector to allow viewing on a larger external display.
4
5LAN Port
The RJ-45 LAN port with eight pins is larger than the RJ-11 modem port and supports
a standard Ethernet cable for connection to a local network. The built-in connector al-
lows convenient use without additional adapters.
Power (DC) Input
The supplied power adapter converts AC power to DC power for use with this jack. Power sup-
plied through this jack supplies power to the Notebook PC and charges the internal battery pack.
To prevent damage to the Notebook PC and battery pack, always use the supplied power
adapter. CAUTION: MAY BECOME WARM TO HOT WHEN IN USE. BE SURE
NOT TO COVER THE ADAPTER AND KEEP IT AWAY FROM YOUR BODY.

jects do not block any of the air vents or else overheating may occur.
1Kensington®Lock Ports
The Kensington®lock ports allow 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.
