The information in this manual is subject to change without notice.
ENERGY STAR® is a government program that offers businesses and
consumers energy-efficient solutions, making it easy to save money while
protecting the environment for future generations.
Please reference ENERGY STAR® related information from
www.energystar.gov.
As an ENERGY STAR® Partner, MiTAC Technology Corporation has
determined that this product meets the ENERGY STAR® guidelines for
energy efficiency.
An ENERGY STAR® qualified computer uses 70 % less electricity than
computers without enabled power management features.
Earning the E SNERGY TAR®
z When every home office is powered by equipment that has earned the
ENERGY STAR®, the change will keep over 289 billion pounds of
greenhouse gases out of the air.
z If left inactive, ENERGY STAR® qualified computers enter a
low-power mode and may use 15 watts or less. New chip
technologies make power management features more reliable,
dependable, and user-friendly than even just a few years ago.
z Spending a large portion of time in low-power mode not only saves
energy, but helps equipment run cooler and last longer.
z Businesses that use ENERGY STAR® enabled office equipment may
realize additional savings on air conditioning and maintenance.
z Over its lifetime, ENERGY STAR® qualified equipment in a single
home office (e.g., computer, monitor, printer, and fax) can save
enough electricity to light an entire home for more than 4 years.
z Power management (“sleep settings”) on computers and monitors can
result in much savings annually.
Remember, saving energy prevents pollution
Because most computer equipment is left on 24 hours a day, power
management features are important for saving energy and are an easy way
to reduce air pollution. By using less energy, these products help lower
consumers’ utility bills, and prevent greenhouse gas emissions.

CHAPTER
Operating Your Computer 2-2
Starting and Stopping the Computer
There are a number of ways to start and stop the computer.
Starting the Computer
You always start the computer using the power button.
A computer starts up with an operating system (OS) existing on the
storage device such as the hard disk; or from an optical disc if you have
the respective modules installed. The computer will automatically load
the OS after you turn it on. This process is called booting.
NOTE: An operating system is the platform for all your software application programs to
run on. Your computer uses the Windows XP operating system.
Stopping the Computer
When you finish a working session, you can stop the computer by turning
off the power or leaving the computer in Standby or Hibernation mode:
To stop in
this mode…

Management” in Chapter 3 for more information.)
Operating Your Computer 2-4
Using the Keyboard
NOTE: Your computer features backlight for your keyboard to help you see the
keyboard keys during poor lighting conditions. Press Fn F8+ to turn it on/off (see Hot
Keys later in this chapter).
Your special shower-proof and dust-proof rubber keyboard has all the
standard functions of a full-sized computer keyboard plus an Fn key
added for specific functions.
The standard functions of the keyboard can be further divided into four
major categories:
z Typewriter keys
z Cursor-control keys
z Numeric keys
z Function keys
Typewriter Keys
Typewriter keys are similar to the keys on a typewriter. Several keys are
added such as the Ctrl, Alt, Esc, and lock keys for special purposes. When
the lock keys (Caps Lock, Num Lock, and Scroll Lock) are pressed, their
corresponding indicators light up.
The Control key is normally used in combination with other keys for
program-specific functions. The Alternate key is normally used in
combination with other keys for program-specific functions. The Escape
key is usually used for stopping a process. Examples are exiting a
program and canceling a command. The function depends on the program
you are using.
Operating Your Computer 2-5
Cursor-Control Keys
NOTE: The word “cursor” refers to the indicator on the screen that lets you know
exactly where on your screen anything you type will appear. It can take the form of a
vertical or horizontal line, a block, or one of many other shapes.
Numeric Keypad
A 15-key numeric keypad is embedded in the typewriter keys as shown
next:
Operating Your Computer 2-6
Numeric keys facilitate entering of numbers and calculations. When Num
Lock is on, the numeric keys are activated; meaning you can use these
keys to enter numerals.
NOTE:
z When the numeric keypad is activated and you need to type the English letter in the
keypad area, you can turn Num Lock off or you can press Fn and then the letter
without turning Num Lock off.
z Some software may not be able to use the numeric keypad on the computer. If so,
use the numeric keypad on an external keyboard instead.
Euro Symbol
You can press the Euro dollar sign on the keyboard.
z To press the Euro sign on the keyboard, hold down either of the Alt
keys and type 0128 on the numeric keypad of your keyboard.
z To press the Euro sign on an UK keyboard, hold down the Alt Gr key
and press 4 (which has an Euro sign on it).
Windows Keys
The keyboard has two keys that perform Windows-specific functions:
Windows Logo key and Application key.
The Windows Logo key opens the Start menu and performs
software-specific functions when used in combination with other keys.
The Application key usually has the same effect as a right mouse
click. (See your Windows manual for more information.)
Function Keys
On the top row of the keys are the function keys: F1 to F12. Function keys
are multi-purpose keys that perform functions defined by individual
programs.
Operating Your Computer 2-7
Fn Key
The Fn key, at the lower left corner of the keyboard, is used with another
key to perform the alternative function of a key. The letter “Fn” and the
alternative functions are identified by the color of blue on the keytop. To
perform a desired function, first press and hold Fn, then press the other
key.
Hot Keys
Hot keys refer to a combination of keys that can be pressed any time to
activate special functions of the computer. Most hot keys operate in a
cyclic way. Each time a hot key combination is pressed, it shifts the
corresponding function to the other or next choice.
You can easily identify the hot keys with the icons imprinted on the
keytop. The hot keys are described next.
Key Description
Switches the wireless LAN radio on and off.
NOTE:
z This function works only if an optional Mini PCI wireless
LAN card is installed.
z The FAA (Federal Aviation Agency) has deemed it unsafe to

Operating Your Computer 2-9
Using the Touchpad
CAUTION: Do not use a sharp object such as a pen on the touchpad. Doing so may
damage the touchpad surface.
NOTE: For optimal performance of the touchpad, keep your fingers and the pads clean
and dry. When tapping on the pad, tap lightly. Do not use excessive force.
The touchpad is a pointing device that allows you to communicate with
the computer by controlling the location of the pointer on the screen and
making selection with the buttons.
The touchpad consists of a rectangular pad and two buttons. To use the
touchpad, place your forefinger or thumb on the pad. The rectangular pad
acts like a miniature duplicate of your display. As you slide your fingertip
across the pad, the pointer (also called cursor) on the screen moves
accordingly. When your finger reaches the edge of the pad, simply
relocate yourself by lifting the finger and placing it on the other side of
the pad.
Here are some common terms that you should know when using the
touchpad:
Operating Your Computer 2-10
Term Action
Point Move your finger on the pad until the cursor points to the
selection on the screen.
Click Press and release the left button.
–or–
Tap gently anywhere on the pad.
Double-
click
Press and release the left button twice in quick succession.
–or–
Tap twice on the pad rapidly.
Drag
and
drop
Press and hold the left button, then move your finger until you
reach your destination (drag). Finally, release the button (drop)
when you finish dragging your selection to the destination. The
object will drop into the new location.
–or–
Gently tap twice on the pad and on the second tap, keep your
finger in contact with the pad. Then, move your finger across the
pad to drag the selected object to your destination. When you lift
your finger from the pad, the selected object will drop into place.
Scroll To scroll is to move up and down or left and right in the working
area on the screen.
The scroll button located between the two buttons under the
touchpad can be used to move vertically in a convenient way.
Press the upper part of the scroll button to move up and the
lower part of the scroll button to move down.
–or–
To move vertically, place your finger on the right edge of the
pad and slide your finger up and down along the edge. To move
horizontally, place your finger on the bottom edge of the pad and
slide your finger left and right.
TABLE NOTE: If you swap the left and right buttons, “tapping” on the touchpad
as an alternative method of pressing the left button will no longer be valid.
Operating Your Computer 2-11
Configuring the Touchpad
You may want to configure the touchpad to suit your needs. For example,
if you are a left-handed user, you can swap the two buttons so that you can
use the right button as the left button and vice versa. You can also change
the size of the on-screen pointer, the speed of the pointer, and so on.
To configure the touchpad, you can use the standard Microsoft driver if
you are using Windows.
Operating Your Computer 2-12
Using the Touchscreen (Optional)
CAUTION: Do not use a sharp object such as a ballpoint pen or pencil on the
touchscreen. Doing so may damage the touchscreen surface.
The touchscreen is a touch-sensitive device that allows you to
communicate with the computer by controlling the location of the pointer
on the screen and making selection with the buttons.
The touchscreen needs a special device driver support that allows you to
easily use the computer without a mouse or touchpad (see chapter 6 for
details).
Here are some common terms that you should know when using the
touchscreen:
Term Action
