HP Omen 30L Fails POST after Windows Update

[hazeyhm]

OMEN 30L Desktop PC GT13-1000a

A few days ago I went to shutdown my PC for the night, clicked update and shut down.

Turned my monitor off, about 30 minutes later I noticed my PC was still on, turned monitor back on to see whats happening, no display signal. Turned my monitor back off and went to sleep.

About 8 hours later the PC is still on and no display signal. Held power button and shut off PC.

Turned it back on and same thing, no display signal to any of my monitors.

I have tried:

Unplugging PC power cable, holding power button while unplugged.

Multiple monitors with multiple cables (HDMI, Display port)

Unplugged monitor power cables

Holding Windows+B , Holding windows +V when powering on

Holding Windows+SHFT+CTRL+B 

Holding Windows+SHFT+CTRL+V

Removing CMOS battery

Jumping the clear CMOS pins on motherboard

Reseating GPU

Reseating CPU

Removing and testing multiple ram sticks/one at a time

Removing SSD

Same thing every time.

Any help is appreciated greatly.

Thanks

Hi @hazeyhm,

Welcome to the HP Support Community!

Thanks for reaching out!

Thanks for detailing all the steps you’ve already tried, that rules out most of the basic fixes. Since your OMEN 30L GT13‑1000a powers on but fails POST after the Windows update, we’re likely dealing with either a corrupted BIOS/firmware or a hardware fault in the motherboard/PSU/GPU chain. Here’s how to move forward:

Attempt BIOS Recovery

Press the Windows + B keys together while holding the power button for about 2-3 seconds, then release the power button but keep holding the keys.

If successful, the laptop may beep, and you will see a BIOS recovery screen.

Follow the prompts to recover or reset the BIOS.

You may also refer to this document.

HP Hardware Diagnostics USB

HP provides a bootable diagnostics tool. If you can get a partial boot, it can generate a failure ID for service.

If the system won’t POST at all, diagnostics won’t run, but this confirms a board‑level fault.

I hope this helps

Take care and have an amazing day ahead! 🚀

Best regards,

Your reply was no help as you mentioned to do things I already stated I have done.

You also mention a laptop, which my post describes clearly that it is a desktop PC.

The computer still does not provide a display signal, any change I can get sent a replacement motherboard?
