Getting into the BIOS mode itself can be tricky and when it is associated with a keyboard issue, then it will be very difficult. When you find that the keyboard is not working during the boot, you cannot enter BIOS and you need to fix it soon with a hack.
This happens mostly with the latest USB keyboards. Therefore, here are some hacks to fix the keyboard errors during boot and in BIOS mode so that you can use it.
How do I fix keyboard errors in BIOS?
Sometimes you may not be able to use your keyboard in BIOS mode due to certain reasons. This is mainly because most of us are using USB keyboards and those ports aren’t booted until the OS is loaded. But you can change this setup and enable the use of USB keyboards in BIOS mode. To do that you need another keyboard from the past.
With the help of a PS/2 keyboard, you can easily navigate in the BIOS mode and enable the appropriate settings to boot the USB interface once the BIOS boots up.
PS/2 keyboards are normally present in all the motherboards and they don’t require any installation. So, they can be used directly in the BIOS mode. Here are the different methods you can try to fix this error in the BIOS with the help of a PS/2 keyboard.
Enabling Legacy USB Support
Once you have connected a PS/2 keyboard, reboot the PC and enter into the BIOS. The keyboard will definitely work and you will be able to enter BIOS without any issues.
Different motherboards have different methods to reach BIOS mode. Therefore, follow the instruction displayed while booting to enter BIOS.
- After entering the BIOS, look for an option called Integrated Peripherals or Default Peripherals. It may also be named differently in your motherboard.
- You just have to find a setting that will let you enable legacy USB support.
- Once you find the setting, enable it and save the changes. Exit the BIOS mode and restart the PC.
- Now again enter into the BIOS mode with your USB keyboard and check whether it is working.
If not move on to the next option.
Disabling Fast Boot
Whenever you power on the computer, it will first boot the BIOS and then the OS. Therefore, if you have preset the USB devices to load after OS boot, then you will not be able to use the keyboard in BIOS mode.
So, you will have to disable the fast boot menu in the BIOS. Follow the previous steps to enter into the BIOS with the help of a PS/2 keyboard.
- Under the boot menu, you will find an option called Fast Boot.
- Disable it, save the changes, and exit the BIOS.
- Restart the PC and enter into the BIOS again to check the working of the USB keyboard.
If it doesn’t work move on to the next option.
Disabling USB 3.0 Boot
Recently motherboards tend to use the USB 3.0 interface during boot and this disables the ability to use the keyboard connected to it. Therefore, disabling it might help with the use of the keyboard.
- Enter into the BIOS and navigate to the Advanced tab in the BIOS menu with the help of a PS/2 keyboard.
- Then locate the USB Single Port Control option and enter it. Look for USB 3.0 in the list and disable it.
- Save the changes and reboot the PC. Enter into the BIOS again to check the working of the keyboard.
If nothing works, you can simply reset the BIOS by clearing the CMOS.
- To perform that, unplug your PC from the power supply and remove all the wires connected to it.
- Unscrew the side panel and locate the CMOS battery in the motherboard panel. It will be pretty easy to locate it. If not check out the motherboard manual for instructions.
- After locating it, remove the battery and wait for a minute.
- You can even press the power button for 30secs to drain the excess voltage.
- Then insert the battery again and plug the power supply.
- Reboot the PC and enter it into the BIOS to check whether the USB keyboard is working.
Why are keyboard errors in BIOS coming?
Keyboard errors occur due to the following reasons:
- USB keyboards are usually encountered with this issue.
- The working of the keyboard might be associated with the OS boot which occurs only after BIOS boot. This disables the ability to use it.
- The keyboard drivers may not be updated and this can also cause errors during usage.
- When BIOS utilizes a USB interface for boot, then you may not be able to use the keyboard.
- BIOS may not recognize the keyboard drivers initially.
Are keyboard errors dangerous for the PC?
No, they don’t do any kind of harm to the PC. Rather, you will not be able to use the keyboard to enter into BIOS and do what you need.
Although you don’t use the BIOS mode frequently, it is always necessary to be able to enter the BIOS mode in case of emergencies.
Therefore, rectifying the errors is important even though they don’t harm the PC. With the help of the above guidelines, you can easily rectify the errors.
Keyboard errors in BIOS don’t occur usually. But they can be easily rectified with the help of some old tech and disabling a few options. Even if nothing works or you don’t have a PS/2 keyboard, you can simply reset the BIOS and get back to using the keyboard easily.
