BIOS Update Bricked my Computer

[dummyau]

I let Windows 11 Update apply an HP BIOS update.  The last thing I saw before the screen went black was the BIOS update being applied.  I did not really pay attention, I just noticed that is what was happening.  When I realized that it had been sitting with a black screen for quite some time, I powered it off and tried to restart and nothing.  When I power it on, the fan starts, and I can hear the hard drive make one movement but nothing appears on the screen.  I have tried everything I can find online.  I created a BIOS USB drive to boot from, I removed the coin battery from the motherboard and with the power disconnected pressed the power button several times and for extended periods of times to reset the CMOS but still nothing happens when I reconnect the power and start with the BIOS USB drive in place (I tried several different USB ports).  I have also tried the pressing the F10 or ESC key while powering on in hopes that it will invoke the boot dialog.     It appears to be permanently damaged by the afore mentioned BIOS update.  

 It seems like the update process should have safeguards to prevent this.   Any tips on anything else to try?    HP Support is sadly silent on recovery options  and the only support offered by their AI chat was to take it an authorized service center which happens to be Geek Squad.  I did and they didn't even offer to try to fix it.  After doing pretty much the same tests that I had already done, their only solution was to just send it to HP for service.  

Is there any hope of recovering a system that has been destroyed by a BIOS update?  Is there any recourse or even a way to get a response from HP about the damage that they did to my PC?

Hi  @dummyau,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I  understand how it feels  when a BIOS update leaves your PC unresponsive.  

To better assist you, could you please share the exact HP model number of your computer ? 

From what you’ve described  fans spinning, hard drive clicking once, but no display  it does sound like the BIOS may not have completed properly. A few things I’d like to confirm with you:

• When you power on, do you see any lights on the keyboard or Caps Lock blinking codes?
• Did you create the BIOS recovery USB using HP’s official BIOS Recovery tool (HP BIOS Update and Recovery utility), or did you manually copy files?
• Have you tried the Windows + B key combination while powering on with the recovery USB inserted? On many HP systems, holding Windows key + B (sometimes Windows key + V) while pressing the power button can trigger the BIOS recovery screen.

Here are a few  steps you can try :

1. BIOS Recovery Hotkey: Insert the BIOS recovery USB, then hold Windows + B and press the power button. Keep holding for 10–15 seconds to see if the recovery screen appears.
2. Different USB Port: try using a  USB 2.0 port for the recovery media. 
3. External Display Check: If it’s a laptop, connect to an external monitor to rule out a display issue.
4. Minimal Hardware Boot: Disconnect all peripherals, remove extra RAM sticks (leave one), and try powering on with just the essentials.
5. Hardware Changes :  Also kindly confirm if there was hardware changes made on the unit . 

If none of these steps bring up the BIOS recovery screen, then possibly the BIOS chip may need to be replaced at the hardware level, which usually requires HP service. But before we conclude that, I’d like to confirm your model and whether the recovery hotkey works at all.

I hope this helps.
