I go this laptop last month, and have never been able to get the lighting to work on the HP Omen. Since coming out of the box, it is not customizable and does not respond to any changes. I also have not been able to get the shortcuts to work either. I have tried updating to the latest Bios just released last week, expecting that to fix things, but still nothing.
I have also had issues with the display resolution changing constantly when I plug into an external HP monitor, and I am having to try to re-configure it constantly.
