Using System Security
This section describes the security options provided with your computer.
System Passwords
The computer provides two levels of password security: administrative-level
(supervisor) and user-level (user). Either password prevents unauthorized access to the
computer. The supervisor password enables full access to all System Setup fields. The
user password enables full access to only the Set User Password and Password on
boot security fields and read access to all other System Setup fields.
If multiple users have access to the computer (such as in a network environment), a
supervisor password can prevent unauthorized access to certain security options.
If You Forget Your Password
It is very important that you do not forget your password. If you do, you cannot access
your system. Write your password down and keep it in a safe place. If you do forget
and cannot find the written note, you will have to contact the reseller of your computer
and possibly take or send it in to them so that you can access the computer again.
Creating a Password
To create a password follow the instructions below:
1. At startup, press to open System Setup.
2. Use to select the Security menu.
Precautions for Password Entry:
You can enter letters or numbers, but you cannot use the function keys, such
as the Shift key. Your computer does not distinguish between capitalized and
lowercase letters in your password. As you type the password, the cursor
moves but your password does not appear on the screen. Choose the type of
password security that is appropriate for your work. If you want to set a user
password, you must set a supervisor password first.
3. Use to select Set Supervisor Password or Set User Password.

Using Power Management Options 53
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
Standby unlike hibernation mode does not store unsaved information on your
hard disk; it's stored only in the computer memory. If there is an interruption in
power, the information is lost. So before putting your computer on standby,
you should save your files.
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 icon to display the Power Options Properties window.
54 Users Manual
3. Click the Power Schemes tab to display the basic power management options.
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.
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.

Using Power Management Options 55
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 whilst you are playing a multimedia program or have an
active USB device connected.
Advanced Power Management Schemes
This section discusses the advanced power management schemes. There are three
methods that you can use to conserve power.
To enter the power management window complete the following:
1. Click Start > Control Panel > Performance and Maintenance.
2. Click icon to display the Power Options Properties window.
3. Click the Advanced tab to display the advanced power management options.

Video Features and Configuration
Your computer includes a TFT LCD or active-matrix display. The capabilities of the
screen plus the video drivers installed on the computer determine the quality of the
image your LCD can display.
The following sections describe the display capabilities of your computer.
Resolution and Colour Depth
The resolution of the LCD is the sharpness of the image it can display. Resolution is
measured by the number of pixels (individual dots) displayed on the entire screen. In
general, the more pixels the LCD can display, the better the image.
Your LCD screen is XGA. In XGA, the screen has a maximum display of 1024x768,
about 786,432 pixels.
The number of colours the LCD can display is measured by how many bits the LCD
uses to represent each pixel:
•16-bit colour can support 64 K (65,536) colours.
•32-bit colour can support 16 M (16.8 million) colours.
All these video modes can be displayed on an external monitor. However, if you
disconnect an external monitor that was attached to your computer and then start the
computer, the LCD may revert to a different resolution than the one you chose for the
external monitor.
Configuring Display Features
The following sections describe how to configure the display settings on your
computer.
Display Resolution Notes:
When Windows XP is initially installed it will automatically adjust the resolution
to maximum available.
