    Dell Diagnostics

  1. 1

    Shut down your laptop. If you are running off of battery power, connect the AC adaptor to the laptop's power port and plug the remaining end into a nearby electrical socket. Turn the computer back on and hold down the "Fn" key until the Dell Diagnostic partition boots up.

  2. 2

    Select the "Test System" option, then select "Express Test." Follow the onscreen instructions.

  3. 3

    Review the results of the Express Test. If you are unable to diagnose the problem, return to the "Test System" screen and select the "Extended Test" option. Follow the onscreen instructions.

  4. 4

    Close the test and Main Menu windows; your laptop will now restart.

    Drive and Memory Problems

  1. 1

    Shut down the laptop and disconnect the power cord and any other attached cables. Turn the computer over and remove the installed battery.

  2. 2

    Examine the underside of the computer and locate the memory compartment cover and the hard drive assembly. If you are having problems with your laptop's memory, remove the screws securing the memory compartment cover and check that the installed memory module is properly seated in its connector. If you are having problems with your laptop's hard drive, remove the screws securing the hard drive bracket (located in the laptop's battery bay); remove the bracket and check that the connector on the hard drive is properly seated.

  3. 3

    Replace the memory module cover or hard drive bracket. Return the previously removed screws to their original locations and tighten them securely. Replace the laptop's battery module, then reconnect the power cord and any other cables.

    Other Hardware Problems

  1. 1

    Open the "Start" menu and select the "Control Panel" option. Click on "Performance and Maintenance," then select the "System" option. Click on the "Hardware" tab, then click on "Device Manager." Review the entries in the device manager to confirm that the computer properly recognises the problem component.

  2. 2

    Open the "Start" menu and navigate to the "All Programs" folder. Search for a folder that has the same name as the problem component. Open the folder and look for an uninstaller application. Launch the uninstaller application and follow the onscreen instructions.

  3. 3

    Insert the installation disc that came packaged with your problem component. Launch the installer application and follow the onscreen instructions.
