HP Notebook PCs - Recovering the BIOS (Basic Input Output System)

This document is for HP notebook computers, including notebooks with HP SureStart architecture.
The computer BIOS might become corrupted from a failed BIOS upgrade or damage from a virus. If you experience any of the following symptoms, recover the BIOS.
  • A 'BIOS APPLICATION ERROR 501' message displays.
  • The computer stops at a black or blank screen when powered on. The BIOS Setup Utility, Hardware Diagnostic Tools, or System Recovery are not accessible.
  • Windows does not start and the Caps Lock or Num Lock light blinks twice or you hear beeps.
  • The computer turns on and you might hear the internal fan, but the display is blank and Windows does not start.
Many HP computers include a feature to recover the last working BIOS version. If this recovery method fails, use another working computer to create a BIOS recovery flash drive to install the latest BIOS file.
  note:
For business computers, your company IT department or local IT service might manage BIOS settings. Confirm this if you cannot access BIOS settings or restore the BIOS.
Step 1: Recover the last working BIOS version
Perform a series of keyboard presses to launch an automatic BIOS recovery. This option is available for many HP computers with a functioning hard drive.
Video overview
  1. Turn off the computer, and then connect the power cord.
  2. Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
  3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
    The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.

    • If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
    • If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.
    • If a BIOS recovery message repeatedly displays, continue to the next step to install an updated BIOS version.
    • If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.
    • If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS.
Step 2: Create a USB recovery drive
Install a BIOS recovery file from the HP website using a USB flash drive. To complete this step, you need a second working computer with an active Internet connection.
Video overview
  1. Obtain the product number for the original notebook that requires a BIOS recovery. This number is typically found on a label on the bottom of the notebook or on the box it shipped in. Go to How Do I Find My Model Number or Product Number? for additional options.
      note:
    The general family name near the keyboard or on the frame around the display is not specific enough for identifying correct download files.

  2. Insert a blank USB flash drive into an available port on the second computer.
  3. Go to HP Software & Driver Downloads and enter the product number of the original computer.
      note:
    If you upgraded the original computer to a new Windows version, in the Selected operating system pane, click Change, select the original operating system that came with your computer, and then click Change.
  4. Click BIOS, and then review the details of the latest available version or the specific version recommended for the recovery. Confirm it is the correct BIOS update before proceeding.
  5. Click Download, and then click Run.
  6. In the InstallShield Wizard window, click Next.
    InstallShield Wizard
  7. Select I accept the terms in the license agreement, and then click Next.
  8. Choose to remove or keep the files after the recovery, and then click Next to open the HP BIOS Update and Recovery window.
  9. Select Create Recovery USB flash drive, and then click Next.
    Create Recovery USB flash drive in HP System BIOS Update Utility
  10. Select your USB flash drive, and then click Next to copy the BIOS file to the drive.
  11. When 'The recovery flash drive was created successfully' displays, click Finish.
  12. Remove the flash drive from the computer.
Step 3: Install the BIOS recovery file
Use the HP emergency BIOS recovery feature and the recovery flash drive to recover the BIOS.
Video overview
  1. Turn off the notebook that requires the BIOS recovery, and then wait 5 to 10 seconds.
  2. Make sure the power cord is connected to the notebook. Keep it connected during the recovery process.
  3. Insert the USB flash drive with the BIOS file into an available USB port on the notebook.
  4. Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
      note:
    On some notebook models, it might be necessary to press and hold the Windows key and the V key.
  5. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
    The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup and to complete the recovery.
    • 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 HP BIOS Update does not display or the issue persists, your computer might not support this function or there is a hard drive issue. Contact HP Customer Support for assistance.
