It’s easy to put off backing up because it takes time. However, if your hard disk suddenly fails, you will lose all the data on it unless you have a separate backup copy.

Use Error-checking and Disk Defragmenter regularly to conserve disk space and improve performance.

Scan all new files for viruses.

This precaution is especially important for files you receive via diskette, email, or download from the Internet.

Take frequent breaks to avoid repetitive-motion injuries and eyestrain.

Do not turn off the computer if a drive indicator light indicates a drive is active.

Turning off the computer while it is reading from or writing to a disk may damage the disk, the drive, or both.

Before turning off the computer, use the Turn Off

Computer command or Standby command. See

“Powering down the computer” on page 113 to learn

more about Standby.

NOTE

The Windows ® XP operating system records information, such as your desktop setup, during its shutdown procedure. If you do not let the Windows ® XP operating system shut down normally, details such as new icon positions may be lost.

Using the keyboard

Your computer’s keyboard contains character keys, control keys, function keys, and special Windows ® keys, providing all the functionality of a full-size keyboard.

Keyboard

Character keys

Typing with the character keys is very much like typing on a typewriter, except that:

The space bar creates a space character instead of just passing over an area of the page.

The lowercase letter l (el) and the number 1 are not interchangeable.

The uppercase letter O and the number 0 are not interchangeable.

The

Caps Lock

key changes only the alphabet keys to upper case—the number and symbol keys are not affected. The caps lock light next to the caps lock key glows when you press the

Caps Lock

key.

Making your keyboard emulate a full-size keyboard

Although your computer’s keyboard layout is compatible with a standard full-size keyboard, it has fewer keys.

A standard full-size keyboard has two

Enter

,

Ctrl

, and

Alt

keys, editing keys, cursor positioning keys, and a numeric keypad.

Pressing the

Fn

key simultaneously in combination with one of the specially marked keys allows you to emulate a full-size keyboard.

Your computer’s keyboard has only one

Enter and one

Ctrl

key.

Most of the time this does not matter. However, some

The

Function keys

The function keys (not to be confused with the

Fn

key) are the

12 keys at the top of the keyboard.

The function keys

F1

through

F12

are called function keys because they execute programmed functions when pressed. Used in combination with the

Fn

key, function keys marked with icons execute specific functions on the computer. For more information, see

“Fn-esse®” on page 160 , or

“Hot Keys” on page 240 .
