HP Omen 35L Fan RGB Problem.

Hello Bill_To

Yes I did system recovery and worked well after that but the same problem again happened after again update. I forgot to mention in my previous comment. Many topics like this have been opened on the forum. Some experienced this problem after a BIOS update, others after a Windows update. At this point i think many user will wait either new bios or windows update.

Greetings @SenolSahin 

Okay, you did a system recovery. The RGB lighting worked until your PC got the same update again.

Is this a Windows update?

Maybe you could do another system recovery and defer the Windows update causing the problem if this update is optional. But you would have to figure out which update is causing the problem.

You could also stop hardware/driver updates from Windows Update as follows:

Enter "Change device installation settings" in Windows Search. Then change this setting from yes to "No".

Save changes and exit.

There is not much else you can do if the update causing the RGB problem is a required Windows update.

You should be able to stop this update if it is coming from HP.

I have this same issue.  I noticed about a week ago my LED (CPU, fans, and Kingston RAM) would stay on after monitor sleep, which was a new behavior and annoying.  I went to the Omen Gaming Hub to see if I could verify the settings.  It froze up each time I tried to access, multiple restarts, same behavior.  I did an uninstall/reinstall and now it doesn't recognize any devices.

Windows Dynamic Lighting works when I am logged in.  If I lock the PC, the lighting stays on and reverts to rainbow/wave type scheme.  I am not aware of a Win update that did this.  My last Win update was 09/09/2025 KB5064401, KB5065426, KB5065221.

Super frustrating for a 35L I've owned for about four months now.  Shouldn't have these problems and this problem involves devices that are proprietary so there's not a lot of options.

I am having the same issue and when using the HP Virtual chat it suggested that the lighting board was bad. Which, after seeing that the issue was not resolved after you replaced yours tells me that it may not be a hardware issue. Mine 1000% stopped working after the recent HP Omen Hub update. Not sure where to go from here....

Seems like a wide spread problem. We will have to wait for Omen to update Gaming Hub. Many are having this issue.

My OMEN 35L is just under two weeks old. After running a few tests in the BIOS, I lost control of the RGB lights through the OMEN Gaming and Advanced Lighting Hub. I tried multiple troubleshooting steps, including a power drain, which did not work, and a full reinstall of the OMEN Gaming and Advanced Lighting Hub, but nothing resolved the issue.

One thing I was not willing to do was buy new parts or make assumptions without first contacting HP support. I learned from HP that this RGB problem is ongoing and, at the moment, there is not much that can reliably fix it long term aside from waiting for the next update, which could take at least two weeks from the date of this post.

I want to thank the person who mentioned using Dynamic Lighting as a temporary work around. At least I can now completely dim the lights using that setting without having to shut down the system each night to turn the lights off.

An update from HP is supposed to be coming on the 15th but in the mean time, just Windows Dynamic Lighting to control your fan RGB lighting by turning on the option.

The problem with using Dynamic Lighting is that when I put my PC to sleep, the RGB lights come back on and run until I get out of sleep mode. So there is a disconnect somewhere with Dynamic Lighting as it does not seem to fully control the RGB lights, specifically in sleep mode.

Do i just have to delete this update for it to work again ? 

do any consequences come once i delete this update on my pc?

[Shai86]

I would absolutely NOT delete any critical updates, as there may be negative consequences if you delete a security update. Even if you did delete the update, the issue can resurface. I highly suggest just using Dynamic Lighting to control the lights as best as you can until the new update (fix) is available. Its irritating, because I use Dynamic Lighting to turn the fan lights off, but unfortunately my fan lights come back on after the PC goes into sleep mode, because Dynamic Lighting seems to lose control of those lights when the PC goes to sleep (go figure).

But as long as I am active on the PC and its not sleep, the fan lights stay off, but the RAM lights stay on. Unfortunately, I cannot turn the RAM lights off with Dynamic Lighting, but they go off in sleep mode (lol). But its much better than the fan lights running 24/7, which is what you get if you don't use Dynamic Lighting in this situation. My PC is barely 3 weeks old. No one wants to deal with this type of issue period, let along within the first 30 days after purchase.
