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 that came installed in the computer or from an electrical outlet. The first time that you use your computer, fully charge the battery by attaching the AC adapter to the computer and to an electrical outlet. Your AC adapter can accept an input voltage of 100 to 120 V AC or 200 to 240 V AC.

All batteries lose their charge if they sit unused for an extended time period. When not used, the provided 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 AC adapter:

1.Plug the AC adapter into the power connector on the right side of the computer (Figure 4).

2.Connect the power cord to the AC adapter and then to an electrical outlet.

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.

To perform a warm (or soft) boot:

1.Click the Start button on the taskbar.

2.Click Shut Down.

3.Select Restart the Computer.

4.Click the Yes button.

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

You can also perform a soft boot by saving your files and pressing <Ctrl+Alt+Del> and then clicking on Shut Down.

You can perform a cold (or hard) boot by pressing the power button to turn the computer off, waiting five seconds, 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 authorized manufacturer’s service center can replace or add any parts inside the chassis.

∙ Follow all the instructions and cautions in your computer user documentation.

Using Your Computer for the First Time 9

∙The LCD has a polarized surface and can be damaged easily. To prevent damage, avoid touching the screen.

∙Use only manufacturer approved AC adapters, automobile adapters and memory modules.

∙Because a portable 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 helps to eliminate some heat. Make sure the fan vent on the side of your computer is not blocked when you use the computer. (See Figure 2 on page 4 for the location of the vent.) Occasionally check the vent 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.

∙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.

∙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 AC adapter 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.

10 User’s Manual

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:

∙If you spill liquid on the internal keyboard or any external devices (such as the floppy drive), drain as much of the liquid 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.

∙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 cause damage despite your efforts to dry.

∙If you spill liquid on the LCD panel, clean it immediately with a soft cloth and denatured alcohol. 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 AC adapter connected to the computer when the computer is not in use. This helps extend the life of the battery and keeps the battery fully charged.

If you will not be using the computer for an extended 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.

Figure 7. Keyboard

Although the layout of the keys on your computer’s keyboard is different from that on a desktop computer’s keyboard, the keyboard feels like a full-sized keyboard when you use it. The distance between the keys (the pitch) is the same as on a fullsize keyboard (19 mm). The travel, or space the key goes down when pressed, is (2.5 mm).

The keys on the keyboard can be grouped into the following categories:

∙Full-sized typewriter keys are arranged like a standard typewriter keyboard and are used for text entry.

∙Function keys, when pressed together with the <Fn> key, enable special functions.

12 User’s Manual

∙Cursor control keys move the cursor. They may perform other functions, depending on your software.

∙Windows keys open Windows menus and perform other special functions.

To clean the computer keyboard, use slightly damp cotton swabs. Scrub the keys and the surface around the keys. Do not allow liquid to drip into the keyboard or you may damage the keyboard.

Using the Numeric Keypad

Your keyboard includes a numeric keypad, which is a group of keys that you can set to type numbers and mathematical symbols, such as the plus sign (Figure 8). A number or symbol on the right corner of each keypad key shows its numeric function.
