If you have a notebook with a defective keyboard, use a regular PS/2 or USB keyboard as a temporary replacement until you have the built-in unit replaced. To avoid hardware conflicts between the defective keyboard and the external replacement, you will need to disable the notebook keyboard.
While Windows will allow you to disable the laptop keyboard in the device manager, the operating system will re-enable the keyboard the next time you boot the computer. Windows will not allow you to disable the keyboard permanently the way you can with some other types of hardware devices. Therefore, disable the keyboard on the laptop motherboard, and avoid conflicts or key errors in Windows.
