Traveling with Your Notebook
This chapter covers all
aspects of using your
notebook while
traveling
Battery and Power Saving
The internal rechargeable Li-Ion battery can power your notebook. The Li-Ion
should keep you on the road for about 2 hours. Higher performance typically
reduces the battery life. When you make your notebook work harder, e.g. by
playing sound and video, or by running disk drives, battery life will be reduced
faster. You can dramatically improve the battery life of your notebook by
taking full advantage of the power management options described below.
Battery-Low Procedure
Your notebook tracks the amount of charge remaining in the internal battery.
When your battery charge level gets low, you will receive several warnings.
When the battery charge drops to about 10%, the computer will issue a
warning message on the display, if advanced power management is enabled in
Windows. At the same time, the notebook will emit an audible beeping sound,
and the LED next to the battery indicator on the front edge of the notebook
will turn red, to alert you of the low battery.
When there is just enough charge remaining to power your system for 3
minutes, Windows will pop up another warning telling you to switch to AC
power or to suspend operation, if advanced power management is enabled in
Windows. At the same time, the red LED next to the battery indicator will start
flashing, and the audible beeping sound will cease. Shortly after that, the
notebook will automatically enter the Suspend-to-Disk mode.
If your battery drains completely without being placed into the Suspend-toDisk mode, you might lose information that has not been saved. It is a good
idea when using battery power to place the unit in suspend mode if you think
you will be leaving the unit for any substantial length of time.
To check your battery charge level in Windows:
Battery Icon
The battery icon on the Windows taskbar provides a rough indicator of the
battery charge level by starting out all blue, i.e. full charge, and becoming gray
as the charge level drops. You can also hold the cursor over the icon to get a
popup reading of battery charge level.
Control Panel
Double clicking on the Power icon in the Control Panel brings up the
Windows power management menu. You can get a reading on the current
4-1
battery charge level here. You can also make changes here to the power
management settings used during Windows sessions.
Responding to a Low Battery
When your notebook alerts you to a low battery, we strongly recommend that
you either immediately use the AC adapter to connect you notebook to a
suitable AC power outlet, or you immediately save all your work and either
suspend your computer to disk, or use the Windows Shut down item in the
Start menu to turn off your system.
If you shut down your computer shortly after the first warning, you will have
plenty of power to save even long files to disk. After you have shut down the
computer or suspended to disk, do not try to restart the computer unless you
have connected the AC adapter, or you have replaced the discharged battery
with a charged one.
Battery Charging
Whenever the Li-Ion battery is installed and the AC adapter is connected to
the notebook, your battery will charge whether the computer is on, off, or in
power saving mode. It will however charge much faster if the computer is
turned off. While the battery is charging, the power indicator next to the
battery icon will turn amber. When the battery is fully charged the indicator
LED will turn green.
NOTE: Do not use battery chargers other than the designated one to
charge this battery pack.
The fastest recharge occurs when the system is off. It takes about 3 hours to
fully charge the Li-Ion battery.
The notebook will stop charging the battery when the temperature of the
system becomes too high.
Battery Conditioning
Each time you charge and discharge the battery, it stores slightly less power.
Similarly, if you do not use the battery for a few days, it will slowly discharge,
and when it is recharged, it will hold less than 100% of the potential charge.
We recommend that you frequently conduct the following operation to keep
your battery in good condition.
1. Disconnect the AC adapter and turn on your notebook.
4-2
2. Allow your battery to fully discharge, ignore any warning alerts, and leave
the system alone until it automatically turns off.
3. After fully discharging your system, connect the AC adapter until the
battery is fully charged.
This operation carried out every few weeks, will maintain the battery
efficiency and help calibrate the electronics that monitor and maintain the
battery charge.
Over time, as the battery is charged and discharged, it gradually stores less
charge. Li-Ion cells generally last for 500 or more cycles before they begin to
deteriorate. You should replace the battery when you notice that it begins to
store significantly less charge.
Changing the Battery
If you frequently use your notebook on the road, you might want to purchase a
spare battery pack. Your notebook only supports standard Li-Ion battery packs
that are designed for your system.
NOTE: Do not dispose the battery in fire. Do not directly connect (short
circuit) the positive (+) and the negative (-) terminals. Never attempt to
disassemble the battery pack.
Changing the battery
1. Turn off the notebook, or suspend to disk.
2. Close the screens cover and turn the computer over.

Button Area
Figure 4-3: Battery
5. The top of the battery has an extra battery charge indicator. The indicator
consists of a button and four small LEDs. When you press the area on the
right side of the indicator, the button, some or all of the red LEDs will start
flashing, depending on how much charge is left in the battery. All four
lights flashing indicates that the battery is fully charged, one light flashing
indicates low battery charge.
6. To replace the battery, slide the battery latch to the back and hold it there,
then slide the battery pack in the compartment until it fits in completely.
Engage the battery latch to secure the battery in the cabinet.

Power Management
In order to make the most of the mobile computing capabilities of your
notebook, you will need to be aware of how to manage the power consumption
of your system. Aggressive power conservation can provide extended
computer usage. Sometimes aggressive power conservation will not be
needed, or you might prefer not to engage it. You should set the default to
match your most common needs. If you use the system primarily as a mobile
system with long-term battery needs, you can use an aggressive setting. If your
battery usage is usually limited, then you might prefer a more moderate
setting. Remember, to reset the default, you must use the System
Configuration Utility program described in Chapter 3.
Your computer is installed with two kinds of power management. One is
transparent, and operates automatically. The other kind is user-programmable,
and you can program how it operates.
Transparent Power Management
Your system is designed to use the Windows Advanced Power Management
(APM) program to transparently reduce system power consumption.
Whenever the processor inside your computer is inactive for a short time, the
transparent power manager idles the processor so that it consumes less power.
When the processor resumes working, it returns to full speed almost
instantaneously with no loss of performance. This kind of power management
is transparent and automatic, and can save a great deal of energy.
Thermal Management
The processor in this computer is extremely powerful. Consequently, it
generates quite a lot of heat when it is working at full speed. Your computer
has an efficient thermal design, which dissipates this heat safely in normal
conditions. If, however, the computer is in an extremely hot environment, and
the processor is working at full speed for sustained periods, the temperature of
the processor may approach a critical level, which could damage the computer.
Your computer monitors the processor’s temperature. Before critical
temperatures can be generated your computer automatically turns on the
internal cooling fan until the heat problem disappears. You may notice the
sound of the fan when this procedure occurs.
Programmable Power Management
There are two programmable power management systems available to you.
4-5
1. Your notebook has power management features built into the System
Configuration Utility program. The utility program provides a more
extensive array of power management options than the Windows power
management discussed below. See Chapter 3 for more information on the
System Configuration Utility.
2. Windows has built-in power management features that can be used when
running under the Windows operating system. Since you can control these
without having to exit to the Setup Program, you might find it useful to
take advantage of the Windows power management. You will be able to
make fine adjustments to power management while working. You can
activate these by double clicking on the Power icon in the Control Panel.
NOTE: If you choose to allow Windows to control the power
management, it will take command of the power management settings
during Windows sessions.
Clicking on the Advanced button allows you to add the Suspend function
to the start menu. It also allows you to set the system to resume normal
function when the modem detects an incoming call. You can also specify
the time period of inactivity before the hard disk is spun down. Spinning
down the disk provides considerable power savings. For optimal battery
life, consider a relatively short period of disk inactivity here.
Suspend Modes
Your computer can either suspend to RAM or suspend to disk. You can use
the System Configuration Utility to program your computer so that is suspends
to RAM or disk. A third, less aggressive power management mode is the
Suspend.
Suspend Mode
In suspend mode, your system turns off and reduces the power consumption of
a range of devices in order to save battery charge. The system will turn off the
backlight of the LCD display, stop the hard disk drive, and put the CPU into
doze mode. You can instantly return to full power by pressing any key or
pointing device.
Suspend-to-RAM
In a Suspend-to-RAM, the contents of your computer’s memory are held
intact, while practically all the rest of the components in your notebook turn
off completely, or reduce power consumption to a minimum. In a Suspend-toRAM, your computer remains active but with the minimum possible power
consumption. You can return the computer to full power by pressing any key.
4-6
If you are operating your notebook on battery power, a fully-charged battery
can maintain a Suspend-to-RAM for many hours.
Suspend-to-Disk
Suspend-to-Disk is really another way of turning off your computer. When
you suspend to disk, the contents of your computer’s memory are copied to
your hard disk drive as a file. When the contents of the memory have been
safely stored to disk, your computer turns off. The next time the computer is
turned on after suspend to disk, the file on the hard disk is quickly read back
into memory. In just a few moments, your computer appears exactly as it was
when you last suspended to disk.
Suspend to disk is very useful for Windows users who like to have many
different programs open and ionized on the Windows desktop. It can take quite
a few minutes to get a busy Windows desktop up and running, and then you
have to shut down each program one by one when you want to turn off your
computer.
NOTE: Don’t use suspend to disk function while transferring files at
network. It may cause your data loss.
Suspend-to-Disk Partition
Suspending to disk requires a special disk partition set up for that purpose.
This partition has already been pre-installed on your notebook. The preinstalled partition is large enough to accommodate most system memory
requirements. If you expand the system memory and get an error message
when you suspend to disk, you will need to increase the size of this partition.
You should not attempt to partition your hard drive unless you are an
experienced user.
Initiating a Suspend mode
Your notebook will suspend fewer than four conditions:
1. You can click on the Suspend button in the Windows Start menu. The
system will turn to suspend mode.
2. Pressing the hot key [Fn]+[F2] combination will suspend the system to
disk.
3. After an automatic suspend timeout, set in the Power menu of the System
Configuration Utility, elapses.
4. After the screen cover of the notebook is closed and no alternative display
has been connected to the system, the system will suspend to RAM or to
disk, depending on the settings in the System Configuration Utility.
4-7
Modem
Your notebook might come with the optional built-in software fax/modem that
allows you to take full advantage of the fax and communications abilities of
your system. In some countries, local regulations may not permit the use of the
fax/modem that is designed for this system. Note that the telephone jack is
covered with a cap and not present if your notebook does not have the
fax/modem option built-in.
The fax/modem is capable of running in two modes, both as a fax and as a
modem, which can be used to connect to other computers. The fax/modem can
send and receive data at up to 56 Kbps and send and receive faxes at up to 14.4
Kbps.
If the fax/modem is present, the notebook is installed with an RJ11 telephone
jack compartment on the rear side. In order to use the fax/modem you need to
first plug a telephone cable into the RJ11 socket, and then use the fax or
communications software to operate the device.
Fax/Modem
Figure 4-4: Fax/Modem Telephone Jack
Faxing
Your modem can allow the computer to send and receive faxes. Any Windows
application, which has a print command, can be used to generate faxes. To
send a fax from within a Windows program, you need only select the fax as
your printer for that document. Then print the document as you would to your
printer.
Modem Communications
If you purchased the modem, you can use it to connect to other computers with
a modem, or to log into networks that allow modem access. Your modem, if
purchased, can be set to emulate a terminal for logging into remote systems. It
4-8
can also be used with login protocols to connect to certain providers and online services, including those provided with Windows.
You should always try to connect at the highest rate of connection available.
Your modem will automatically negotiate the connection and establish the
actual rate of transmission of information.
To connect to anything with your modem, you will usually need to sign on
with some provider or dial-in to another computer already set to receive such
connections. Since such electronic connections are an important resource for
computer users, Windows comes with its own software for making such
connections, as well as with software from some other major service
providers.
You can also use your modem in conjunction with financial software to
perform your banking and pay your bills electronically.
Keep in mind that your modem is a phone, but unlike other phones, it is very
sensitive to noise. If you find that your modem has a lot of disconnect
problems, you might see if you can reduce the noise in your phone lines.
Internet and the World Wide Web
One of the most useful functions of your modem is to allow you to connect to
the Internet or to browse the World Wide Web. The Internet is not a network,
but a vast interconnection of networks. The Internet provides a connection to
the world. You can send messages to anywhere on earth. You can login and
use library catalogues. World Wide Web browsers, such as the Microsoft
Internet Explorer browser built-into Windows, allow you to have access to
text, images, sound and video stored on the Internet. To enter the Internet, you
will need to log your computer into one of these networks.
Safety and Operation
The notebook does not have a handle or rough surface for a sure grip, so
use a carrying case when travelling. At times, you may want to put both
the case and the notebook within a larger briefcase to conceal the system
and reduce the risk of theft.
Do not use the notebook in an unstable location. Serious damages could
result if the system should fall.
Avoid rough handling of you notebook. Jolts to the system can damage
components or result in data loss.
4-9
!
Avoid high and low temperatures when shipping or storing your notebook.
Do not place the system in close proximity to a source of heat or dust.
The batteries will not operate as well under extremes of temperature. If a
battery is left in the sun and gets quite hot, it is apt to fail to charge. Once
it cools down, you will be able to charge it again.
Protect your modem. It is designed to work on an analog phone system.
Before you hook up your modem, check to find an analog line.
Travel Tips
It is a good idea to load common printer drivers onto your notebook. This
will allow you to print from many printers at your destination, even if you
do not carry your own printer with you.
Take along a bootable diskette drive, just in case there is damage to your
hard disk drive.
Travel can present considerable risk of system shock or theft. Complete a
full backup before travelling.
Be familiar with your System Configuration Utility settings, or print a
copy of them. In case there is damage to those settings, while you travel.
If you will be travelling to another country, check with your travel agent to
determine whether or not you will need a special adapter to use the
electrical outlets.
If you do a lot of travelling, you might find it useful to purchase an
acoustic coupler for your modem, to allow connection even where
compatible phone jacks cannot be found.
Hand your notebook to an airport attendant rather than setting it on the
conveyor for security checks, this will help reduce the possibility of theft.
Password protects your system with at least one level of password, to help
preserve your data.
Brand or physically mark your notebook to make for easy identification.
If you will be using an Internet provider or other on-line service, call
ahead to find out local access numbers for your destination.
In case your destination does not have outlets near convenient workspaces, you might want to pack a short extension cord.

Using a Computer Lock
You may want to secure your computer to a heavy object such as your desk or
other immovable object to discourage theft.. The easiest way to do this is to
purchase an optional Kensington Micro saver security cable. Your notebook
has an anchor point for such a cable.
4-11

To use this cable follow these instructions:
1. Loop the cable through or around some part of a heavy object. Make sure
there is no way for a potential thief to slip the cable off the object.
2. Pass the locking end through the loop.
3. Insert the cable’s locking end into the anchor point on your notebook, give
the key a quarter turn and remove it. The computer is now securely locked.
