3 From the Windows® desktop, click the Start button, point to All Programs, point to Accessories, and click 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.

2 Disconnect the external keyboard.

3 Turn on the computer.

4 From the Windows desktop, click the Start button, point to All Programs, point to Accessories, and click Notepad.

5 Type some characters on the external 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 (see "Contacting Dell" on page 139).
