You can try to recover the BIOS using a key press combination or a USB recovery drive.

NOTE: 

These recovery processes are not supported on computers with the HP Sure Start feature.

Recover the BIOS using a key press combination

Many HP computers have an HP BIOS Restore tool that might be able to recover the BIOS from an earlier version and restore basic function. This tool might not be able to recover the BIOS, depending on the cause of the corruption.

NOTE: This recovery process is not supported on computers with the HP Sure Start feature.

Restoring the BIOS on HP Computers with a Key Press Combination

Learn how to restore the BIOS on your HP computer with a key press combination.

1. Turn off the computer and be sure that the AC adapter is connected to power.

2. Press and hold the Windows + b keys, and then simultaneously press the power button.

3. After 2 to 3 seconds, continue to press and hold the Windows + b keys, but release the power button. You might hear a series of beeps.

   • If the HP BIOS Update screen is not displayed, repeat the previous steps but press the Windows + v keys. If the screen is still not displayed, your computer might not support the feature or there is a hard drive issue.

   • If the power light turns off, the power button was held too long. Repeat the previous steps, making sure that you press and hold the power button for only 2 to 3 seconds.

   • If a BIOS recovery message is displayed repeatedly, see Recover the BIOS using a USB recovery drive.

   • If a message displays that the computer improperly shut down or a boot problem is detected, follow the on-screen instructions to resolve the error.

   • If Windows starts, update to the latest BIOS version. Go to HP Consumer Notebook PCs - Updating the BIOS (Basic Input Output System) (Windows) or HP Business Notebook PCs - Updating the BIOS (Basic Input Output System) for more information.

   The HP BIOS Update screen is displayed and the recovery begins automatically.

   If this recovery method fails, use another working computer to create a BIOS recovery flash drive to install the latest BIOS file.
