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.

Turning On the Computer

To turn on the computer’s power for the first time:

1. Push to the right and hold the cover latches on the front of the cover.

2. Lift up the cover.

3. Press and then release the power button (Figure 5).

The power light is on when the computer’s power is on.

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.

Turning Off Your Computer

If your computer has a Windows operating system, turn off

your computer by performing the shutdown procedure

described in this section. Otherwise, you may lose data.

APM(Advanced Power Management) mode

To turn off the computer:

1. Click Start on the taskbar.

2. Click Shut Down.

3. Select the shut down option.

4. Click OK or Yes.

•If the operating system is Windows 98/ Me, the computer turns off.

•If the operating system is Windows NT, you receive a shutdown message

and you must press the power button to turn off the computer.

ACPI(Advanced Configuration and Power

Interface) mode

If your operating system supports ACPI and you want to shut down the computer

just by pressing the power button, then follow next steps to set the menu in Power

Management Properties. Also see “Using Power Management Options” on page

63 and the documentation accompanying your operating system.

To set the menu;

1. Select Power Management Properties in Control Pannel.

2. Select the operations of power button.

•Standby mode: operates as Power On Suspend mode. (See ”Rest Mode” on

page 64 for more information.)

information.)

Restarting Your Computer

You may need to restart (reboot) your computer when installing hardware or

software or if the computer does not respond to your input. A warm (or soft) boot

prompts you to save your files, turns off the computer, and then restarts the

computer. A cold boot turns off the computer without saving your files.

To perform a warm (or soft) boot:

1. Click Start on the taskbar.

2. Click Shut Down.

3. Select the restart option.

4. Click OK or Yes.

5. Save your files if prompted. Your computer reboots.

Using Your Computer for the First Time 9

Do not perform a cold boot unless your keyboard and

touchpad have no effect and you cannot perform a warm

boot.

When you perform a cold boot, you lose data unless it was

saved to a storage medium.

You can also perform a soft boot by saving your files and pressing

<Ctrl+Alt+Del>. In ACPI, you can perform a cold(or hard) boot by pressing the

power button to turn the computer off, waiting five second, and then pressing the

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.
