Using Your Computer for the First Time 5
Using Your Computer for the First Time
This section gives you detailed information on using your computer for the first
time.
Attaching the AC Adapter
Your computer runs on power from the battery in the computer or from an
electrical outlet. The first time that you use your computer, fully charge the battery
by attaching the power cord to the computer and to an electrical outlet.
All batteries lose their charge if they sit unused for an
extended time period. When not used, battery can discharge
fully in 2 to 3 months. The battery may have discharged in the
time it took for the computer to go from the factory to you.
To attach the power cord:
1. Plug the AC adapter into the power connector on theback side of the computer
(Figure 4).
2. Connect the power cord to the AC adapter and then to an electrical outlet.

6 Using Your Computer for the First Time
The battery starts charging as soon as you plug the power cord into an electrical
outlet. The battery charges faster if the computer is turned off during charging.
If the battery is fully depleted and the computer is turned off, the battery charges
in about 3 hours. If the computer is turned on, the battery charges in about 5 hours.
When the battery is charging, the battery charge light is amber. When the battery
is fully charged, the light turns green.
See ”Using the Battery” on page 32 for more information on using your
computer’s battery.

Using Your Computer for the First Time 7
Understanding POST
When you turn on your computer, a routine called POST (Power-On Self-Test)
automatically runs to test the computer components. System logo appears on the
screen during POST.
Screen messages are built into the computer to report both normal and abnormal
system conditions. If an error message appears, take any action suggested in the
message. If the message identifies the error condition but does not suggest any
corrective action, write down the message and contact manufacturer or an
authorised service center for assistance. (See ”Troubleshooting” on page 95.)
Adjusting the LCD Display
You may wish to adjust the LCD (Liquid-Crystal Display) when you begin using
your computer. A TFT (Thin-Film Transistor) LCD does not require adjustment
for contrast because the contrast is set to remain at maximum.
To adjust the LCD:
•Press <Fn+Right Arrow> to increase the display brightness.
•Press <Fn+Left Arrow> to decrease the display brightness.

power button to turn the computer on.
Tips for Using Your Computer
The following information helps you avoid potential problems as you use your
computer:
Do not try to disassemble your computer. Opening the
system chassis voids your warranty. Only an authorised
manufacturer service center can replace or add any parts
inside the chassis.
•Follow all the instructions and cautions in your computer user documentation.
•The LCD has a polarized surface and can be damaged easily. To prevent
damage, avoid touching the screen.
•Use only approved AC adapters, auto adapters, memory modules and other
options.
•Because a notebook computer is small and has restricted air flow around
components, it is more likely to overheat than a desktop computer. A fan
inside your computer runs when needed to help eliminate some heat. Make
sure the fan vent on the right side of your computer is not blocked when you
use the computer. (See Figure 1 on page 3 and Figure 2 on page 4 for the
location of the vent.) Occasionally check the vents and remove any
accumulated dust on the outside.
•Avoid using or storing the computer in extremely hot or cold areas, such as a
car on a hot day. Keep the computer away from heaters and out of direct
sunlight. Exposure to excessive heat may damage computer components.

10 Using Your Computer for the First Time
If you have left your computer in a hot place, let it cool down slowly to room
temperature (with the LCD panel open) before using it.
•Do not remove the memory-module compartment door, or try to install a
memory module when the computer is on. (See ”Bottom View of Computer”
on page 4 for the location of the door.)
(For information on installing memory modules, see “Installing a Memory
Module” on page 86.)
•Set up your computer work area to avoid physical strain. Sit with your back
straight and supported by your chair. Adjust your chair or work table so that
your arms and wrists can remain in a relaxed position, parallel with the floor.
Avoid bending or twisting your wrists as you work. Your hands should “float”
slightly above the keyboard. Refer to a book on office ergonomics for more
information on setting up your work area.
•Take frequent breaks from working at the computer to rest your eyes and
stretch your muscles.
•Remember to save your data files frequently and to make backup copies of
your files.
Traveling with Your Computer
If you are traveling by airplane, follow these tips:
•Take the computer with you as carry-on luggage. Do not check the computer
with your baggage.
•Allow the computer and disks to go through the X-ray security devices. Do
not hand-carry disks through the walk-through metal detectors, which can
cause loss of data.
•Make sure that the battery is charged or the power cord is easily accessible.
You may be required to turn on the computer for airport security personnel.
•Be prepared to turn off the computer during take off and landing.
•Contact your airline for information about using an optional airline adapter to
power your computer while traveling by airplane.

Using Your Computer for the First Time 11
Handling Spills
Do not spill anything on your computer. The best way to avoid spills is to avoid
eating and drinking around your computer. If you do spill something on your
computer, turn off your computer, unplug it immediately, and do the following:
•If you spill liquid on the keyboard, drain as much of the liquid from the
keyboard as possible. Be careful not to let the liquid drip onto the LCD panel.
Allow the system to dry for several days before trying to use it.
•If you spill liquid on an external keyboard or keypad, unplug it and drain as
much of the liquid as possible. Allow the keyboard to sit at room temperature
for a full day before trying to use it.
Sweet liquids leave a sticky residue that may jam the
keyboard despite your efforts to dry it.
•If you spill liquid on the LCDpanel, clean it immediately with a soft cloth and
denatured alcohol. Do not use water, window cleaner, acetone, aromatic
solvent, or dry, rough towels to clean it.
Some liquids damage the polarized LCD screen. If your
screen is damaged, contact your authorized manufacturer’s
service center for a replacement.
Storing the Computer for Long Periods
If possible, leave the power cord connectedto the computer andan electrical outlet
when the computer is not in use. This extends the life of the battery and keeps the
battery fully charged.
If you will not be using the computer for a long period of time (a month or more),
you should charge the battery until it is completely full. After you have done so,
remove the battery from the unit.

12 Using the Keyboard
Using the Keyboard
Your computer has an 87/88-key keyboard (Figure 6). By pressing designated key
combinations, you can have accessto all the key functions of a full-sized keyboard.
Figure 6. Keyboard
Although the layout of the keys on your computer’s keyboard
is different from that on a desktop computer’s keyboard, the
keyboard feels like afull-sized keyboard when you use it. The
distance between the keys (the pitch) is the same as on a full-
sizekeyboard(19mm).The travel,or space thekey goes
down when pressed, is also the same (3 mm).
The keys on the keyboard can be grouped into the following categories:
•Full-sized Alphanumeric typewriter keys are arranged like a standard
typewriter keyboard and are used for text entry. The Windows keys on either
side of the spacebar open Windows menus and perform other special
functions.
•Function keys, when pressed together with the <Fn> key, enable special
functions.
•Cursor and Screen control keys move the cursor. They may perform other
functions, depending on your software.
