Omen uninstall then reinstall now screen flickering on Omen manual startup

[K2Rin]

Yesterday I was uninstalling programs on my computer and decided to uninstall Omen as at the time I thought I didn't need it. Next day I realize I needed it because the green led light on my tower didn't shut off on its own as it normally does. So, I reinstalled Omen and on startup of the program the screen is flickering which didn't happen before I uninstalled it.

The screen flickering happens only when Omen is open on screen, I can exit the program and the flickering stops. I have shut down and turned on my computer multiple times and every time I have to manually open Omen for my green led to turn off with the screen flickering every time. I have gone into the advanced settings for Omen in apps and features and have tried the repair and reset options but neither have helped.

Is there a way to turn off my computers green led without Omen?

Hi@K2Rin, Welcome to the HP Support Community!

I understand when you power on your laptop the screen keeps flickering on your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Does the issue persist in BIOS?

As you mentioned when you power on your laptop the screen keeps flickering on your laptop.

If the issue does not persist in BIOS try updating the graphics driver and BIOS on your PC.

Try performing a BIOS default on your PC and check if it helps.

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

Also, Uninstall the graphics driver from the device manager and install the latest drivers and BIOS from the links below.

You can try updating the drivers on your PC using an HP support assistant.

If the screen is flickering in BIOS, it is certainly a hardware issue with your PC.
