Testing the keyboard in the BIOS (Basic Input/Output System)

Testing the keyboard in the BIOS (Basic Input/Output System) is a useful way to determine if the keyboard hardware is functioning correctly. To do this, you’ll need to access the BIOS or UEFI settings of your computer. Here are the general steps to test the keyboard in the BIOS:

1. Restart or Power On Your Computer:
   • If your computer is off, turn it on. If it’s already running, you may need to restart it.
2. Access the BIOS/UEFI:
   • During the early boot process, there’s usually a brief moment when you can access the BIOS or UEFI settings. This moment is typically indicated on the screen with a message like “Press [Key] to Enter Setup” or “Press [Key] for BIOS.” The key to access the BIOS can vary but is often one of the following: F2, F12, Del, Esc, or another key. Refer to your computer or motherboard’s documentation for the specific key.
3. Navigate the BIOS/UEFI:
   • Once you’re in the BIOS/UEFI, use the keyboard to navigate through the settings. You can usually do this using the arrow keys to move between options and the Enter key to select or open submenus.
4. Typing Test:
   • To test the keyboard, you can simply type in the BIOS/UEFI. For example, you can enter a password if required, or you can use the arrow keys to navigate to a text field and type some characters.
5. Observe Keyboard Functionality:
   • As you type, check to see if the characters you’re entering are displayed correctly on the screen. If you can navigate through the BIOS menus and type without any issues, this indicates that the keyboard is functioning properly at a hardware level.
6. Exit the BIOS/UEFI:
   • If the keyboard functions as expected in the BIOS/UEFI, you can exit the settings. Typically, you will save any changes you made (if necessary) and then exit. This may also be done using keyboard shortcuts within the BIOS/UEFI.

If your keyboard works as expected in the BIOS/UEFI, but you’re experiencing issues in your operating system, the problem may be related to software or drivers. In this case, you may need to troubleshoot your operating system or check your keyboard drivers.
