AC A D A P T E R C O N N E C T O R Attaches an AC adapter to the computer. The AC adapter converts AC power to the DC power required by the computer. You can connect the AC adapter with your computer turned on or off.
CAUTION: The AC adapter works with electrical outlets worldwide. However, power connectors and power strips vary among countries. Using an incompatible cable or improperly connecting the cable to the power strip or electrical outlet may cause fire or equipment damage. NOTICE: When you disconnect the AC adapter cable from the computer, grasp the connector, not the cable itself, and pull firmly, but gently to help prevent damage to the cable.

and images to appear larger and can benefit people with vision impairments. To display a program at a specific resolution, both the video card and the display must support the program, and the necessary video drivers must be installed. NOTE: Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system. If you choose a resolution or color palette that is higher than the display supports, the settings adjust automatically to the closest supported values. To set the display resolution and refresh rate for your display, perform the steps in the following section that corresponds to the operating system your computer is using.

Microsoft Windows XP

1 Click StartSettingsControl Panel. 2 Under Pick a category, click Appearance and Themes. 3 Under Pick a task., click the area you want to change, or under or pick a Control Panel icon, click Display. 4 In the Display Properties window, click the Settings tab. 5 Try different settings for Color quality and Screen resolution. NOTE: As the resolution increases, icons and text appear smaller on the screen.

Windows Vista

1 Click the Windows Vista Start button , and click Control Panel. 2 Under Appearance and Personalization, click Adjust screen resolution. 3 In the Display Settings window, under Resolution, slide the slide bar to the left or right to decrease/increase the screen resolution. 4 Click How do I get the best display? for further instructions. If the video resolution setting is higher than that supported by the display, the computer enters pan mode. In pan mode, the entire video image cannot be displayed at one time, and the taskbar that usually appears at the bottom of the desktop may no longer be visible. To view the parts of the video image that are not visible, you can use the touch pad or track stick to move (or pan) the image up, down, left, and right. NOTICE: You can damage an external monitor by using an unsupported refresh rate. Before adjusting the refresh rate on an external monitor, see the users guide for the monitor. 42
Using Both a Monitor and Your Computer Display
You can attach an external monitor or projector to your computer and use it as an extension of your display (known as dual independent display or extended desktop mode). This mode allows you to use both screens independently and drag objects from one screen to the other, effectively doubling the amount of viewable work space. To use extended desktop mode, perform the steps in the following section that corresponds to the operating system your computer is using.
1 Connect the external monitor, TV, or projector to the computer. 2 Click StartSettingsControl Panel. 3 Under Pick a category, click Appearance and Themes. 4 Under Pick a task., click the area you want to change, or under or pick a Control Panel icon, click Display. 5 In the Display Properties window, click the Settings tab.

1 In Outlook Express/Windows Mail, click Tools, click Options, and then click Security. 2 Click Do not allow attachments to remove the checkmark.
CHECK THE TELEPHONE LINE CONNECTION CHECK THE TELEPHONE JACK CONNECT THE MODEM DIRECTLY TO THE TELEPHONE WALL JACK USE A DIFFERENT TELEPHONE LINE
Verify that the telephone line is connected to the jack on the modem (the jack has either a green label or a connector-shaped icon next to it). Ensure that you hear a click when you insert the telephone line connector into the modem. Disconnect the telephone line from the modem and connect it to a telephone, then listen for a dial tone. If you have other telephone devices sharing the line, such as an answering machine, fax machine, surge protector, or line splitter, then bypass them and connect the modem directly to the telephone wall jack. If you are using a line that is 3 m (10 ft) or more in length, try a shorter one.

Service Tag A bar code label on your computer that identifies your computer when you access Dell Support at support.dell.com or when you call Dell for customer service or technical support. setup program A program that is used to install and configure hardware and software. The setup.exe or install.exe program comes with most Windows software packages. Setup program differs from system setup. shortcut An icon that provides quick access to frequently used programs, files, folders, and drives.

Strike Zone Reinforced area of the platform base that protects the hard drive by acting as a dampening device when a computer experiences resonating shock or is dropped (whether the computer is on or off). surge protectors Prevent voltage spikes, such as those that may occur during an electrical storm, from entering the computer through the electrical outlet. Surge protectors do not protect against lightning strikes or against brownouts, which occur when the voltage drops more than 20 percent below the normal AC-line voltage level. Network connections cannot be protected by surge protectors. Always disconnect the network cable from the network connector during electrical storms. SVGA super-video graphics array A video standard for video cards and controllers. Typical SVGA resolutions are 800 x 600 and 1024 x 768. The number of colors and resolution that a program displays depends on the capabilities of the monitor, the video controller and its drivers, and the amount of video memory installed in the computer. S-video TV-out A connector used to attach a TV or digital audio device to the computer. SXGA super-extended graphics array A video standard for video cards and controllers that supports resolutions up to 1280 x 1024.

Video memory is usually faster than system memory. The amount of video memory installed primarily influences the number of colors that a program can display. video mode A mode that describes how text and graphics are displayed on a monitor. Graphics-based software, such as Windows operating systems, displays in video modes that can be defined as x horizontal pixels by y vertical pixels by z colors. Character-based software, such as text editors, displays in video modes that can be defined as x columns by y rows of characters. video resolution See resolution. virus A program that is designed to inconvenience you or to destroy data stored on your computer. A virus program moves from one computer to another through an infected disk, software downloaded from the Internet, or e-mail attachments. When an infected program starts, its embedded virus also starts. A common type of virus is a boot virus, which is stored in the boot sectors of a floppy disk. If the floppy disk is left in the drive when the computer is shut down and then turned on, the computer is infected when it reads the boot sectors of the floppy disk expecting to find the operating system. If the computer is infected, the boot virus may replicate itself onto all the floppy disks that are read or written in that computer until the virus is eradicated.
