If the display is blank

If the display is difficult to read

To verify that the problem is with the mouse, check the touch pad

1. Shut down the computer.

2. Disconnect the mouse.

3. Turn on the computer.

4. At the Windows

desktop, use the touch pad to move the cursor around, select an icon, and open it.

If the touch pad operates correctly, the mouse may be defective.

Check the system setup program settings Verify that the system setup program lists the correct device for the pointing device option.

(The computer automatically recognizes a USB mouse without making any setting adjustments.)

Test the mouse controller To test the mouse controller (which affects pointer movement) and the operation of the touch pad or mouse

buttons, run the Mouse test in the Pointing Devices test group in the Dell Diagnostics.

Reinstall the touch pad driver See "Reinstalling Drivers and Utilities."

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

NOTE: If you are using a program that requires a higher resolution than your computer supports, it is recommended that you attach an external monitor

to your computer.

Check the battery If you are using a battery to power your computer, the battery charge may be depleted. Connect the computer to an

electrical outlet using the AC adapter, and turn on the computer.

Test the electrical outlet Ensure that the electrical outlet is working by testing it with another device, such as a lamp.

Check the AC adapter Check the AC adapter cable connections. If the AC adapter has a light, ensure that the light is on.

Connect the computer directly to an electrical outlet Bypass power protection devices, power strips, and the extension cable to verify

that the computer turns on.

Adjust the power properties Search for the keyword standby in the Windows Help and Support Center (Windows Help in Windows 2000).

Switch the video image If your computer is attached to an external monitor, press <Fn><F8> to switch the video image to the display.

Adjust the brightness Press <Fn> and the up- or down-arrow.

Move the external subwoofer away from the computer or monitor If your external speaker system includes a subwoofer, ensure that

Connecting to a Wireless Local Area Network

DellPrecision™MobileWorkstationM20User'sGuide

Determining Your Network Type

Connecting to a Wireless Network in Microsoft®Windows®XP

Determining Your Network Type

Wireless networks fall into two categoriesinfrastructure networks and ad-hoc networks. An infrastructure network uses routers or access points to connect

several computers. An ad-hoc network does not use routers or access points and consists of computers that broadcast to one another. For additional

assistance with setting up your wireless connection, go to support.dell.com and search for the keyword wireless setup.

Connecting to a Wireless Network in Microsoft®Windows®XP

Your wireless network card requires specific software and drivers in order to connect to a network. The software is already installed. If the software is

removed or corrupted, follow the instructions included in the user's guide for your wireless network card. The user's guide is located on your Drivers and

Utilities CD (that came with your computer) in the "User's Guides-Network User's Guides" category. The user's guide is also available on the Dell Support

website at support.dell.com.

When you turn on your computer, a pop-up appears from the network icon in the notification area whenever a network is detected in the area for which your

computer is not configured.

1. Click either the pop-up or the network icon to configure your computer for one of the available wireless networks.

The Wireless Network Connections window lists the wireless networks available in your area.

NOTE: These networking instructions do not apply to internal cards with Bluetooth®wireless technology or cellular products.

NOTE: To configure a wireless computer running the Windows 2000 operating system, see the user's guide that came with your wireless network

adapter.

NOTE: Your Dell QuickSet power management software can disable your wireless card. If your wireless card is not working, see your QuickSet Help by

clicking the QuickSet icon in the taskbar, then clicking Help.

NOTE: Most wireless networks are of the infrastructure type.

1

infrastructure network

2

ad-hoc network

2. Click to select the network you want to configure, and then click Connect or double-click the network name in the list. If you select a secure network

(identified by a icon), you must enter a WEP or WPA key when prompted.

Your network is configured automatically.

After your computer is configured for the wireless network you selected, another pop-up notifies you that your computer is connected to the network

you selected.

Thereafter, whenever you log on to your computer in the area of the wireless network, the same pop-up notifies you of the wireless network

connection.

NOTE: Network security settings are unique to your network. Dell cannot provide this information.

NOTE: Your computer can take up to 1 minute to connect to the network.

with a red background in the Network Connections section of the Control Panel.

Note that enabling the Internet Connection Firewall does not reduce the need for virus-checking software.

For more information, see the Help and Support Center (Microsoft®Windows®XP) or Windows Help (Windows 2000).
