Failed BIOS Update

[P_J_K]

HP Omen Command center requested a BIOS update be applied, I did not check which version as it was from the installed software. After the update completed the PC immediately would not POST, and is stating via beep codes and led blinks that the BIOS is corrupt. 

I built the USB stick to recover BIOS however, how can I do so without being able to see a display to select options? It will not power on monitors. I attempted to remove the video card and utilize on motherboard video options on the motherboard (915479-601), however still no video. (Monitor does not find signal from any output, displayport or hdmi)

What is the procedure to recover corrupted BIOS updates in this scenario? Motherboard replacement?

If the only option is replacement, how can I obtain a replacement s/p 915479-601 motherboard? The part is not even listed as an option to purchase for the model via HP's parts site.

Welcome to the HP Support Community.

Let's perform a power reset as per HP standards:

Ensure your device is OFF.

Unplug all the external devices (If any).

Disconnect the power from the computer

Press and hold the power button for about 30 seconds.

Connect the power supply

Press the power button to turn on your device and check if the issue persists.

If the issue persists, after the above steps, try the below:

To recover an earlier version of the BIOS on your computer:

1. Turn off the computer.

2. With the computer off, press and hold the Windows key and the B key at the same time.

3. Still pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows and B keys until the BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

   NOTE: 

   If the key presses do not work, press and release the Power button, and then immediately, press the Windows and B keys at the same time, repeatedly, until the computer beeps or opens the BIOS update screen.

   The power LED light remains on, and the screen remains blank for about 40 seconds before anything displays on the monitor. You might also hear beeping sounds. Eventually, an HP BIOS Update screen displays and the BIOS update begins automatically.

   

   • If the HP BIOS Update screen displays proceed to the next step.

   • If the HP BIOS Update screen does not display, do one of the following depending on the condition:

   • Computer starts into Windows: The computer starts into Windows if the power button and keys are released too soon. Repeat the previous steps, holding the power button down for 2 or 3 seconds.

   • Power LED light turns off: The computer turns off if the power button is pressed and held down too long. Repeat the previous steps, holding the power button down for between 2 and 3 seconds.

   • After repeated attempts, the HP BIOS Update screen does not open: Your computer does not support this function or it has a hardware problem that is preventing the tool from opening.
