HI @tpruitt599,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Recovering from a failed BIOS upgrade can be a tricky process, but there are several steps you can take to try to restore your system. Here's a step-by-step guide for recovering an HP laptop with a failed BIOS upgrade:

Step 1: Attempt a Hard Reset

Disconnect All External Devices:

• Remove any USB drives, external hard drives, and other peripherals.

Remove Power Sources:

• Unplug the power adapter and remove the battery (if it’s removable).

Drain Residual Power:

• Press and hold the power button for about 15-20 seconds to drain any residual power.

Reconnect Power Sources:

• Reconnect the power adapter (and battery if it was removed).

Attempt to Power On:

• Press the power button to see if the system will boot up.

Step 2: BIOS Recovery Using a Key Press Combination

HP laptops often have a built-in BIOS recovery feature that can be accessed using a specific key press combination:

Turn Off the Computer:

• Make sure the computer is completely off.

Press and Hold the Windows + B Keys:

• While holding these keys, press and hold the power button for about 2-3 seconds, then release the power button but continue holding the Windows + B keys.

Wait for the BIOS Recovery Screen:

• If the recovery screen appears, follow the on-screen instructions to restore the BIOS.

Step 3: Use an HP BIOS Recovery USB Drive

If the key press combination doesn’t work, you can create a BIOS recovery USB drive using another computer:

Download BIOS Update:

• On a working computer, go to the HP Support website and download the latest BIOS update for your specific model.

Prepare a USB Drive:

• Format a USB drive to FAT32. Make sure it's empty.

Create BIOS Recovery USB:

• Extract the BIOS update files to the USB drive. Look for a file named something like HPBIOSUpdate.exe or similar and run it. Follow the instructions to create the BIOS recovery USB drive.

Use the USB Drive to Recover the BIOS:

• Insert the USB drive into the non-working HP laptop.
• Follow the steps for the key press combination (Windows + B) as described earlier, but this time the laptop will use the USB drive to recover the BIOS.

I hope this helps.

Take care and have a good day.
