HP All-in-One - 20-c434
Microsoft Windows 10 (64-bit)

I performed a recommended BIOS update, and it apparently was interrupted. Now my unit powers up but there is no display. The hard drive light is lit and the fan is operating.

Hi @Qmsgirl-55,

 

Welcome to HP Support Community.

 

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

 

It sounds like your HP All-in-One 20 is experiencing a BIOS corruption issue due to the interrupted update. Here’s a step-by-step guide to try and recover the BIOS.

 

Perform a Hard Reset

  • Power off your computer and unplug the power cord.
  • Hold the power button for 15-20 seconds to discharge any residual power.
  • Plug the power cord back in and attempt to power it on.

BIOS Recovery with a USB Drive

You can attempt to recover the BIOS using a USB flash drive:

Steps:

Prepare a USB Flash Drive (at least 8GB):

  • Use another computer to download the BIOS recovery file.
  • Visit the HP Support site and enter your PC’s model number to find the correct BIOS file.
  • Download the BIOS file, then extract the file to the root directory of the USB drive (not in any folder).

Initiate BIOS Recovery:

  • Insert the USB flash drive into the affected computer.
  • Hold down the Windows + B keys (or Windows + V for some models), and while holding, press the power button for 2-3 seconds, then release it.
  • Continue holding the Windows + B (or V) keys for 40 seconds until you hear beeping sounds or the screen displays the BIOS update process.

Follow On-Screen Instructions:

  • If the BIOS recovery screen appears, follow the prompts to restore the BIOS.
  • Allow the process to complete without interruption.

Use BIOS Reset Jumper (Last Resort)

If none of the above works, you may need to open your All-in-One and reset the BIOS using the jumper on the motherboard. This is usually done by temporarily removing or repositioning the jumper for a few seconds.

 

I hope this helps.

 

Take care and have a good day.
