Fans are not working properly after BIOS F.13 Rev.A

[siskoo]

I have updated my BIOS version from F.11 Rev.A to F13 Rev.A.
After that both my fans are not working properly.  Sometimes both of them are working and I have sudden stops while heavy usage. I haven't had that before the update. While I have that stops I can't control fan speed from Omen Gaming Hub, except that I can control them. After that stops, fans are starting to work as normal. I also uninstalled the application totally but it didn't make any changes. I am sure it's because of the BIOS update.

I got Error 90b. I have never gotten any error code since I bought that laptop until the BIOS update. I can't downgrade my BIOS to an old version.

My laptop is OMEN by HP Laptop 17-cm2003nt (7P6D7EA).

Hi @siskoo 

Welcome to the HP Support Community!

Thanks for explaining everything so clearly—and I’m really sorry you’re dealing with this frustrating fan behavior after the BIOS update. 

It’s especially annoying when your system was running smoothly before, and now you’re getting Error 90b and inconsistent fan control during heavy usage.

Here’s a structured approach to help stabilize things:

🛠️ Steps to Resolve Fan Issues After BIOS Update

Perform a Hard Reset

• Shut down your laptop completely.
• Disconnect the power adapter and any external devices.
• Press and hold the power button for 15 seconds.
• Reconnect power and boot up. This helps clear temporary hardware detection glitches.

Reset BIOS Settings

• Restart and press F10 repeatedly to enter BIOS Setup.
• Go to the Exit tab and select Load Setup Defaults, then Save and Exit.
• This ensures no custom settings are interfering with fan behavior.

Run HP Hardware Diagnostics

• Restart and press Esc, then F2 to launch diagnostics.
• Run the Fan Test under Component Tests.
• If either fan fails, it may confirm a hardware issue triggered by the firmware update.

Uninstall and Reinstall OMEN Gaming Hub

• Go to Settings > Apps > Installed Apps and uninstall OMEN Gaming Hub and HP System Event Utility.
• Then delete the folder:
  C:\Program Files\WindowsApps\AD2F1837.OMENCommandCenter_*
  (You may need to take ownership of the WindowsApps folder to do this.)
• Reinstall OMEN Gaming Hub and HP System Event Utility from the Microsoft Store or your model’s HP Support page.

Check for HP SDK Updates

• On the HP Support site, download the latest HP SDK Package and OMEN Gaming Hub SDK for your laptop model.
• These packages help the Gaming Hub communicate properly with BIOS and fan controllers.

Monitor Fan Behavior

• After reinstalling everything, test fan control under different workloads.
• If the issue persists, document when the fans stop and whether the Gaming Hub loses control again.

If the fan test fails or the issue continues even after these steps, it may require a service check—especially since BIOS downgrades aren’t supported on your model. 

Let’s get your OMEN back to peak performance without those sudden stops.

I found the reason of the problem. It doesn't happen while power boost option of GPU is disabled. I am really sure it's because of BIOS. Could you inform technical staff to fix that issue in next BIOS update? And also fan test on UEFI didn't fail when i don't use power boost option.

Thanks for sharing your findings—that’s a really helpful observation. You’re absolutely right to suspect the BIOS update as the root cause.

HP’s technical team is aware of these post-update anomalies, and users have been encouraged to report them through official support channels to help prioritize a fix

You’ve done a great job narrowing this down!!
