System Management
Using Power Management Options
Your computer includes Power Management options that can help the battery charge
last longer and extend the life of the battery. Power-management options will slow
down or shut off system components when the components are not being used.
Power management may slow down system performance. Your computer runs fastest
with the power cord attached, when power management is disabled.
In the next sections, basic and advanced methods of power management will be
discussed.
Basic Power Management Schemes
This section discusses the basic schemes of power management when the computer is
operating on battery power or using AC power.
Standby vs. Hibernation
Hibernation is a state where the contents of memory are stored in a special file
on the hard disk, and Standby simply keeps a small holding current through
the memory to keep the data. You are more likely to sustain loss of data in
Standby mode so it is recommended to save all open files before entering
Standby.
Changing Devices:
Do not change PC Cards while in standby or hibernate modes.
To enter the power management window complete the following:
1. Click Start > Control Panel > Performance and Maintenance.
2. Click
62 Users Manual
icon to display the Power Options Properties window.
3. Click the Power Schemes tab to display the basic power management options.
Power Schemes Tab
4. Select the time that you wish each of the following actions to occur in Battery and
AC power mode.
Turn off monitor
Turn off hard disks
System standby
System hibernates
Turning off the monitor and HDDs will save a substantial battery power, therefore
when in battery only mode select the shortest time practical.
a Hibernate Mode (Power Management or Manual Method)
When hibernation is used, your computer turns off and when you power up again,
everything is restored exactly as you left it—including programs and documents
you may not have saved or closed. Everything in memory gets saved to the HDD,
and the monitor and hard disk get turned off.
System Management 63
If You Reinstall Windows:
You should re-establish hibernate in power options by opening Power
Options Properties window and click on the Hibernate tab then click
“Enable Hibernation”.
Hibernate Tab
Frequent Interruptions:
If you experience frequent interruptions, you might also consider putting your
computer into automatic hibernation after a specified number of minutes using
the power management options.
a Standby Mode (Power Management or Manual Method)
Standby is used mainly for conserving battery power in your notebook computer. It
also gives you the benefit of getting right back to your work without waiting for the
computer to restart. Standby turns off your monitor and hard disks, placing your entire
system in a low-power state. When you return to your computer, restores your desktop
exactly as you left it. It is recommended that you do not enter standby mode with less
than 20% battery power.
5. Click OK to set your power management options and close the window.
Rest Key:
The manual  key combination will not activate Standby or Hibernate
modes while you are playing a multimedia program or have an active USB
device connected.

Using the Battery
Your computer uses a smart rechargeable Lithium-ion (Li-ion) battery pack for power
when the AC adapter is not attached to an electrical outlet. The smart battery gives a
accurate measurement of the current battery capacity which helps extend operating
time by enabling effective power management in operating systems that take
advantage of the accurate information supplied by the battery.
Charging the Battery
Your computer’s battery starts charging automatically when you connect the power to
the computer and to an electrical outlet.
Approximate charging time for the Li-Ion battery is 2 hours. While the battery is
charging normally, the battery charge light on the computer is amber. When the battery
is fully charged, the light changes to green.
When you use a new battery pack for the first time or use a battery after a long period
of storage, the initial battery life is shorter than normal. Normal battery life resumes
after a few discharge-recharge cycles.
Follow these rules for charging your battery:
x A battery normally discharges power when not used for long periods of time.
Be sure to recharge the battery every two months when it is not in use.
x Make it a practice to discharge your battery fully before recharging the battery.
This can help extend the life of the battery.
x Do not attempt to charge the battery in temperatures of under 5oC or over 45oC
All batteries eventually wear out and lose the ability to hold a charge. You may
need to replace your battery pack after a year of average usage.
Battery charging time may differ depending on system environment or using
condition.

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.
x Follow all the instructions and cautions in your computer user documentation.
x The LCD has a polarized surface and can be damaged easily. To prevent
damage, avoid touching the screen.
x Use only approved AC adapters, auto adapters, memory modules and other
options.
x 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 heat. Make sure the fan vent
on the left side of your computer is not blocked when you use the computer.
Occasionally check the vents and remove any accumulated dust on the outside.
x 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. 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.
x Do not remove the memory-module compartment door, or try to install a
memory module when the computer is on. (For information on installing
memory modules, see “Installing a Memory Module” on page 74.)
x 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.
x Take frequent breaks from working at the computer to rest your eyes and
stretch your muscles.
x Remember to save your data files frequently and to make backup copies of your
files.
System Management 77
Travelling with Your Computer
Air Travel
If you are travelling by air, follow these tips:
x Take the computer with you as carry-on luggage. Do not check the computer
with your baggage.
x 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.
x 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.
x Be prepared to turn off the computer during take off and landing.
Locking your Computer

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:
x 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.
x 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.
x If you spill liquid on the LCD panel, clean it immediately with a soft cloth and
denatured alcohol or a proprietary LCD screen cleaner. 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 connected to the computer and an 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.

Glossary
AC adapter
The AC (or alternating current) adapter regulates current coming into your
computer from the wall outlet. The current at the wall outlet is alternating current
and needs to be changed by the adapter to DC (direct current) before your
computer can use it for power.
ACPI
ACPI (Advanced Configuration and Power Interface)- a method for describing
hardware interfaces in terms abstract enough to allow flexible and innovative
hardware implementations and concrete enough to allow shrink-wrap OS code to
use such hardware interfaces.
BIOS
BIOS stands for basic input/output system. The BIOS is software (often called
firmware) that is independent of any operating system. It enables the computer to
communicate with the screen, keyboard, and other peripheral devices without
using programs on the hard disk.
The BIOS on your computer is flash BIOS, which means that it has been recorded
on a flash memory chip that can be updated if needed.
Boot
To start your computer. A cold boot resets the entire computer and runs through
all computer self-tests. A warm boot clears out computer memory only.
Boot disk
A disk containing operating system programs required to start your computer. A
boot disk can be a floppy disk, hard drive, or compact disc.
Byte
The basic unit of measure for computer memory. A character—such as a letter of
the alphabet—uses one byte of memory. Computer memory is often measured in
kilobytes (1,024 bytes) or megabytes (1,048,576 bytes).
Each byte is made up of eight bits. For more information on bytes and bits, see an
introductory book on computers.
Cache memory
Cache is very fast, zero-wait-state memory located between the microprocessor
and main memory. Cache reduces the average time required by the
microprocessor to get the data it needs from the main memory by storing recently
accessed data in the cache.
102 Users Manual
CardBus
CardBus technology enables the computer to use 32-bit PC Cards. Hardware in
the computer and the Windows operating system provide support for the 32-bit
cards. The voltage of 32-bit cards (3.3 volts) is lower than that of 16-bit cards (5
volts). The 32-bit cards can transmit more data at a time than the 16-bit cards, thus
increasing their speed.
CMOS memory
CMOS (complementary metal oxide semiconductor) memory is powered by the
CMOS battery. The System Setup settings and other parameters are maintained in
CMOS memory. Even when you turn your computer off, the information in
CMOS memory is saved.
COM port
COM stands for communication. COM ports are the serial ports in your computer.
Compact Disc
A compact disc (CD).
Conventional memory
The first 640 KB of system memory. Operating systems and application programs
can directly access this memory without using memory-management software.
Disk
The device used by the computer to store and retrieve information. Disk can refer
to a floppy disk, hard disk, or RAM disk.
Disk cache
A software device that accumulates copies of recently used disk sectors in RAM.
The application program can then read these copies without accessing the disk.
This, in turn, speeds up the performance of the application.
A cache is a buffer for transferring disk sectors in and out of RAM. Data stored in
a disk cache is a copy of data already stored on the physical disk.
DMA (direct memory access)
A method of transferring data from a device to memory without having the data
pass through the microprocessor. Using DMA can speed up system performance.
DPMS
Display Power Management Signalling. Displays or monitors that comply with
this can be managed by the Power Management features found in the system
setup.
Floppy disk
A removable disk, also called floppy or diskette.
Glossary 103
Hard drive
Also called fixed disk. A hard drive is connected to the computer and can be
installed or removed. Data written to a hard drive remains until it is overwritten
or corrupted.
The 2.5-inch hard drive in your computer was designed for use in a notebook
computer. Because hard drives in notebook computers are smaller than those in
desktop computers, their maximum storage capacity may be less than that of
desktop hard drives. However, because of their smaller size, the drives handle
shock and vibration better than larger drives, which is important for a notebook
computer.
I/O
Input/output. Refers to peripheral devices, such as printers, that are addressed
through an I/O address.
I/O address
I/O stands for input/output. Peripheral devices, such as printers, are addressed
through the I/O port address.
IRQ (interrupt request line)
The IRQ is a hardware line that a device uses to signal the microprocessor when
the device needs the microprocessor’s services. The number of IRQs is limited by
industry standards.
LCD (liquid-crystal display)
The LCD screen on your computer differs from the display screen of a desktop
monitor. Most desktop monitors use CRT (cathode-ray tube) displays, which
work by moving an electron beam across phosphor dots on the back of the screen.
The phosphor dots light up to show the image. LCDs use a liquid-crystal solution
between two sheets of polarizing material. Electric current passing through the
liquid aligns the crystals so that light can or cannot pass through them, creating an
image.
MB (megabyte)
1,024 kilobytes.
Megabit
1,048,576 bits or about 128 kilobytes.
Operating system
A program that supervises the computer's operation, including handling I/O.
Application programs and users can request operating-system services. A user
might request operation-system services to copy files or format a disk. An
application program might use the operating system to obtain keyboard input,
write data to a file, or write data to a screen.
104 Users Manual
PC Card
PC Card stands for personal computer card. The Personal Computer Memory
Card International Association (PCMCIA) defines the standards used to develop
all PC Cards. PC Card types include: modems, Ethernet adapters, SCSI adapters,
ATA cards, and memory cards.
PC slot
The PC slot is the hardware slot in the computer where the PC Card is placed.
Pixel
A pixel is an individual dot in a graphic displayed on your computer. The pixels
are so close together that they look as though they are connected. An LCD screen
displays thousands or millions of pixels.
Plug and Play
A plug and play operating system automatically configures computer components
to work with your system. With this type of operating system, you normally do
not need to set jumpers on devices or set memory addresses or IRQs.
RAM (random access memory)
The computer's system memory, including conventional and extended memory.
You can write to and read from RAM. Information stored in RAM is temporary,
and is erased when the system is turned off.
Refresh rate
The refresh rate is the rate at which the image on the LCD screen is rewritten to
the screen. A fast refresh rate helps keep the image from flickering.
Resolution
The resolution is the sharpness or clarity of the image on your LCD screen.
Resolution is measured by the number of pixels the computer’s screen can
display. For example, a resolution of 800 x 600 means that the screen can display
800 pixels in row and can display 600 rows. The more pixels displayed, the higher
the resolution and the better the image.
ROM (read-only memory)
Permanent computer memory dedicated to a particular function. For example, the
instructions for starting the computer when you first turn on power are contained
in ROM. You cannot write to ROM. (ROM is not the same as RAM).
Sector
Also known as disk sector. The portion of a track that is numbered and can hold
a specified number of characters (usually 512 KB).
Glossary 105
Shadow RAM
A write-protected area of RAM that contains a copy of the BIOS. As the computer
boots, the BIOS is copied from its permanent location in ROM to RAM. The
BIOS can be executed much faster in RAM than in ROM. The BIOS remains in
shadow RAM until you turn off the computer.
TFT (thin film transistor) LCD
A TFT LCD uses a separate transistor circuit to control each pixel. This
technology provides the best resolution for an LCD screen. A TFT LCD is also
sometimes called an active matrix LCD.
