HP Omen 17 won't boot after BIOS update

[Simunt]

After updating my BIOS in December 2025, my laptop now won't turn on. 

I've tried everything - cleared out any residual power (even went so far as to remove the battery and run it off mains). I've reseated components, and have tried the WIN KEY + B (and also WIN KEY + V) method to try and reset the bios. I've downloaded a new version of the bios to a USB stick but no joy. Pressing the power button just results in it lighting up for a second, then turning off. No sign of the fans kicking in, the screen remains blank. I think something has gone on the motherboard but although I have an IT background I have no electrical experience.

After speaking with Omen on Facebook, I  have tried the CMOS reset several more times, holding down the WIN + V keys for 2 minutes after releasing the power button after 2 seconds. Nothing - laptop appears dead. I can confirm that the USB stick is set up exactly as per their video. I have followed the method again just to be sure but the computer remains lifeless.

I don't have a warranty but it's pretty shocking that a BIOS update can render a reasonably new expensive laptop useless.

• Remove the Battery: If your model has a removable battery, take it out.
• Clear Residual Power: Hold the power button down for approximately 15 seconds to drain any leftover power.
• Reconnect Power: Reinstall the battery (if removable) and plug the adapter back in.
• Attempt to Restart: Try turning on the laptop.

LED Blink Codes: 

• Observe any blinking LEDs (like Caps Lock) which can indicate error codes.
