  • The keyboard is broken and the BIOS key doesn’t work.
  • The motherboard is broken.
  • The BIOS chip on the motherboard has failed to work.

  2. Type msinfo32 in the Run window and hit Enter.
  3. In the System Information window, locate the BIOS Version/Date field and check the BIOS version.

Step 2: Go to the official website of your motherboard to see the latest BIOS version. If the found BIOS version is earlier than that of the official website, it means that your BIOS is outdated. Then you need to update it with the given instructions.

Step 3: Download the latest BIOS file from the official website.

Step 4: Extract the downloaded BIOS Zip file to an empty USB flash drive (formatted with FAT32).

Step 5: Boot into the BIOS and locate the BIOS update utility. To be specific, find options like EZ Flash, Q-Flash, or something like that. The option varies according to the motherboard manufacturer.

Step 6: Follow the prompted instructions to stat the update process. Then wait for the finish of the process.

Method 4: Reset the BIOS/CMOS

If you cannot enter BIOS still, reset the BIOS/CMOS by removing the BIOS battery. Resetting BIOS/CMOS will restore your BIOS settings to original settings, which means that any changes have been made to BIOS will be undone. Here are the general steps to reset the BIOS.

Please note that the specific steps for resetting BIOS can vary on exact PC brands and models. You should back up the passwords and custom configurations before resetting BIOS because this operation will remove these items too.

Step 1: Turn off the computer and unplug all the connected cables including the power cables and the peripheral devices.

Step 2: Open the PC case and find the CMOS battery on the motherboard. Being small and round, this battery offers power to the BIOS and retains its configurations.

Step 3: Remove the battery and leave it out of the PC for a few minutes. You may need to use a screwdriver to take out the battery.

Step 4: Place the battery back and fasten it.

Step 5: Close the PC case and reconnect all the cables. Then reboot your PC.
