GT15-0304 WON'T BOOT

[CITYBUS]

I have an Omen pre-built (model G15-0304) that stopped booting. It won't even boot to BIOS. I tried pressing the caps lock key on my keyboard while it was at the black screen after I pressed the power button, and it did not activate caps lock. I've read that that means it's failing to POST at all. Unless anyone has any suggestions, I feel like my last resort is to try to manually update the BIOS from a raw BIOS file. I'm open to any other suggestions, but I especially am looking for the raw BIOS file for my model. I can't boot to Windows, so I can't use the HP installer. 

Can anybody point me in the right direction or does anyone have the raw file I need to try it? Thanks!

@CITYBUS,

Welcome to our HP Community forum!

If your OMEN 25L isn’t even reaching POST (no keyboard lights, no BIOS logo), that usually points to a hardware-level issue, not just Windows. Before attempting a risky manual flash, here are some steps worth trying:

Basic checks:

1. Power drain – Unplug the system, hold the power button for 15–20 seconds, then reconnect and test.

2. Minimal boot – Reseat RAM, GPU, and storage. Try one stick of RAM only, or use integrated graphics if available.

3. CMOS reset – Unplug, remove the coin-cell battery or use the CMOS jumper for a few minutes, then retry.

4. Check PSU – A failed or unstable PSU can also prevent POST.

 

BIOS recovery (official HP method):

HP does not provide raw .bin/.rom BIOS files. Instead, you download a BIOS SoftPaq (self-extracting .exe) from your product’s HP support page:

• Go to your PC's HP Software and Driver Downloads.

• Under BIOS, download the latest BIOS package, which is version F.36 Rev.A.

• Run it on a working Windows PC. It will give you an option to Create a Recovery USB — this is the official HP BIOS Update & Recovery utility.

• Insert that USB into your OMEN, hold down Windows key + B (sometimes Windows + V), and power on. If supported, you’ll see a BIOS recovery screen.

 

Alternative (using Rufus):

If the HP tool doesn’t let you build a recovery drive, you can manually make one:

1. On another PC, download the BIOS SoftPaq for your model.

2. Extract the contents (the .exe is a compressed archive; use 7-Zip or run it once and check the C:\SWSetup\SPxxxxx folder). Inside you’ll find the BIOS image (.bin or .fd).

3. Use Rufus to format a USB drive as FAT32 (important for UEFI).

4. Copy the BIOS image file(s) to the root of the USB.

5. Plug the USB into the OMEN, then try the same Windows + B power-on key combo.

Caution: A forced flash is VERY risky -if the wrong file or an incomplete flash is applied, the board can be permanently bricked. If you’re still under warranty, HP support is the safer route.

Bottom line: Try power/CMOS resets first. If still no POST, use the official BIOS recovery USB created from HP’s support site.

Rufus + extracted files is a fallback method, but only if you’re comfortable with the risks.

Of course, the reality is: for a PC that doesn’t even respond at all, the standard “create HP BIOS recovery USB” approach I discussed is essentially useless -it would only work if the system can POST to some degree. Anything beyond that becomes hardware-level intervention, either via a programmer or RMA/replacement.

In that case, check your warranty status, and/or see if HP Support can assist you further.

Thanks for your quick response! I should have mentioned that I tried all of those (reseating everything with known good parts, resetting the CMOS, etc.). I think the only option left is to use the BIOS reset. I have already made the bootable USB recovery drive. I just haven't tried it yet. That's my next method. My PC is out of warranty, so I can't even contact HP support. I feel like this is my last option.

@CITYBUS,

And you are sure your motherboard is getting power -meaning: your PSU is not defective?

I assume you got the HanaL motherboard (SSID: 89EB)?

This is an expensive motherboard to replace: the least expensive HanaL motherboard purchase option via eBay would still set you back $248.20 (with coupon code): G1N M81916602 Hp AM4 WIN Motherboard OMEN 25L GT150304 | eBay.

Please let us know if the BIOS reset worked out...

Sorry for the delayed response. We were out of town until this evening. Yes, I'm sure the PSU is good. I'm using known good RAM, CPU, PSU, GPU...everything. I tried dumping the 089EB.bin file directly into the root of a USB drive and force the recovery by holding Windows + B, Windows + V, Windows + ESC, only B, and only V. I also tried renaming the file AMIBOOT.ROM, BIOS.bin, and HPBIOS.fd and trying all of those methods to force recovery. I tried placing the .bin file inside a folder structure (Hewlett-Packard > BIOS > Current) and forcing recovery with each of these same file names. None of these options worked. The LED light on the USB stick just flashes at a constant, slow rate from the moment I power on the board. The CPU fan spins up and maintains a constant speed, as does the rear case fan. This leads me to believe that the board is not electrically dead, as there is no variation in speeds. I assume that means the voltage delivery is correct and steady. After all of those failed, I used a CH341A programmer to read and back up the BIOS file that was on the chip and tried manually flashing the 089EB.bin to the chip. The Read step was successful, the Erase step was successful, the Write step was successful, and the Verify step was successful. After that, I tried booting again with the same results. I tried opening the backed up BIOS dump in UEFITool, and, according to ChatGPT, what I see in UEFITool indicates that the BIOS may be encrypted to prevent tampering. I'm now stuck in a position of needing a known, working BIOS file to try to manually flash to the chip unless you or anyone else has any other suggestions. I'm going to try to contact HP "customer service" tomorrow, but based on previous experience, I don't have much hope. A, I don't pay for "customer service," and B, I probably know 1,000 times more than whichever 23 year old, untrained representative I'd get put in touch with even if I did.

But thank you in advance for the help you've provided so far and any other help you may be able to provide!

@CITYBUS,

My friend, may I say that you’ve done a very thorough job of troubleshooting -clearly far beyond what the average user (or front-line HP support) would normally attempt! -Unfortunately, you’ve also run into one of the main limitations: HP does not distribute raw, “known-good” BIOS chip images (.bin/.rom) for end-user flashing. What you’ve already tried (renaming .bin files, AMIBOOT.ROM, HPBIOS.fd, etc.) confirms that the board is not accepting recovery media at all...

So, honestly, from my (anecdotally infused) POV, this narrows the options to:

• Official path: To my knowledge, HP only supports BIOS recovery via the SoftPaq packages and its built-in recovery tools. If your board won’t respond to that, then the official resolution (and unofficially, mine as well) is board replacement. Since you mentioned contacting HP -if the system is in or near warranty, that’s the best path.

• Unofficial path: You’ve already used a CH341A programmer. The obstacle is that HP BIOS builds are often encrypted/signed. Even if you write an image directly to the chip, the platform controller can reject or fail to execute it if the signature doesn’t match. That’s why your flash “verified” but still gave you a dead boot. Unfortunately, sans an HP-signed recovery image, a manual flash usually will not succeed.

• Other hardware checks: It’s still worth ruling out the basics -for example, some Omen boards will appear “power on, fans spinning, no POST” if the CPU isn’t fully seated, if the VRM protection has tripped, or if there’s a subtle short on the board. But since you’ve already swapped in known-good PSU, RAM, GPU, etc., it does sound like the motherboard itself is the culprit, i.e. is toast.

Bottom line: For systems that don’t even initialize recovery mode, there really isn’t a “secret” raw BIOS file we can point you to. If the board is otherwise electrically alive, but the firmware partition is unreadable or rejected, the only reliable next step is replacement through HP service or sourcing a working replacement board like the eBay purchase option I pointed to.
