When to Use the Dell Diagnostics

If you experience a problem with your computer, perform the checks in Lockups and Software Problems and run the Dell Diagnostics before you contact Dell for technical assistance.

It is recommended that you print these procedures before you begin.

NOTICE: The Dell Diagnostics works only on Dell™ computers.
NOTE: The Drivers and Utilities CD is optional and may not ship with your computer.

Start the Dell Diagnostics from either your hard drive or from the Drivers and Utilities CD (also known as the ResourceCD).

Starting the Dell Diagnostics From Your Hard Drive

The Dell Diagnostics is located on a hidden diagnostic utility partition on your hard drive.

NOTE: If your computer cannot display a screen image, contact Dell (See Contacting Dell).

  4. Diagnostics can be invoked one of two ways:

NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop. Then shut down your computer and try again.
NOTE: If you see a message stating that no diagnostics utility partition has been found, run the Dell Diagnostics from the Drivers and Utilities CD.

The computer runs the Pre-boot System Assessment, a series of initial tests of your system board, keyboard, hard drive, and display.

If the Pre-boot System Assessment completes successfully, you receive the message Booting Dell Diagnostic Utility Partition. Press any key to continue.

  1. Press any key to start the Dell Diagnostics from the diagnostics utility partition on your hard drive.

Starting the Dell Diagnostics From the Drivers and Utilities CD

If the battery status light flashes green and orange, the battery is too hot to charge. Shut down the computer, disconnect the computer from the electrical outlet, and then let the battery and computer cool to room temperature.

If the battery status light rapidly flashes orange, the battery may be defective. Contact Dell (see Contacting Dell).

Check the battery temperature — If the battery temperature is below 0° C (32° F), the computer will not start up.

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.

Eliminate possible interference — Turn off nearby fans, fluorescent lights, halogen lamps, or other appliances.

Adjust the power properties — See Configuring Power Management Settings.

Reseat the memory modules — If the computer power light turns on but the display remains blank, reinstall the memory modules (see Memory).

Ensuring Sufficient Power for Your Computer

Your computer is designed to use a 65-W or 90-W AC adapter. However, for optimum system performance, you should always use a 90-W adapter.

Using less-powerful AC adapters, including the 65-W AC adapter, will cause you to receive a WARNING message.

Docking Power Considerations

Due to the extra power consumption when a computer is docked to the Dell D/Dock, normal computer operation is not possible on battery power alone. Ensure that the AC adapter is connected to your computer when the computer is docked to the Dell D/Dock.

Docking While the Computer Is Running

If a computer is connected to the Dell D/Dock or Dell D/Port while the computer is running, presence of the docking device is ignored until the AC adapter is connected to the computer.

AC Power Loss While the Computer Is Docked

If a computer loses AC power while docked to the Dell D/Dock or Dell D/Port, the computer immediately goes into low-performance mode.

Touch Pad or Mouse Problems

Check the touch pad settings —

  1. Click the Start button, click Control Panel, and then click Printers and Other Hardware.

  2. Click Mouse.

  3. Try adjusting the settings.

Check the mouse cable — Shut down the computer. Disconnect the mouse cable, check it for damage, and firmly reconnect the cable.

If you are using a mouse extension cable, disconnect it and connect the mouse directly to the computer.

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 (see 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 (see Dell Diagnostics).

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

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 (see Windows Help and Support Center).

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

If only part of the display is readable

Connect an external monitor —
