Keyboard / External Keyboard Problems
NOTE: Use the integrated keyboard when running the Dell Diagnostics or the system setup program. When you attach
an external keyboard, the integrated keyboard remains fully functional.
Check the following if you encounter any issues with your external keyboard:
Check the Keyboard Cable
Shut down the computer. Disconnect the keyboard cable and check it for damage, and firmly reconnect the cable.
If you are using a keyboard extension cable, disconnect it and connect the keyboard directly to the computer.
Check the External Keyboard
1. Shut down the computer, wait for one minute, and turn on the computer again.
2. Verify that the numbers, capitals, and scroll lock lights on the keyboard blink during the boot routine.
3. From the Windows desktop, click All Programs > Accessories > Notepad.
4. Type some characters on the external keyboard and verify that they appear on the display. If you cannot verify these steps, you may
have a defective external keyboard.
Check the Integrated Keyboard
To verify that the problem is with the external keyboard, check the integrated keyboard:
1. Shut down the computer.
2. Disconnect the external keyboard.
3. Turn on the computer.
4. From the Windows desktop, click All Programs > Accessories > Notepad.
5. Type some characters on the internal keyboard and verify that they appear on the display. If the characters appear now but did not
with the external keyboard, you may have a defective external keyboard.
Contact Dell.
Run the Keyboard Diagnostics Tests
Run the PC-AT Compatible Keyboards tests in the Dell Diagnostics. If the tests indicate a defective external keyboard, Contact Dell.
