Change Brightness on OMEN Laptop

[michaelseko1992]

Hello everyone. Long time HP user here but first time poster. I've looked through every corner of the web for a solution to this issue but I could not find one. I have an Omen gaming laptop, model I7-CB1002CA. Everything works flawlessly except for the two function keys (F1+F2) to change the brightness of the internal display (it's stuck on what I believe is max brightness). I've already updated the BIOS and every other driver direct from HP's support page for this laptop and installed all windows updates but the issue persists. When I got the laptop I immediately upgraded the M.2 SSD to a larger capacity and re-installed Windows so I can't tell you if the keys worked when I first got it. If anyone can point me in the direction to a solution for this issue I would be forever grateful. It's not too bad during the day, but at night the screen is way to bright. Thank you!

Hi@michaelseko1992,

Welcome to HP Community!

I understand that the Brand new HP Omen 17screen stuck on MAX brightness.

Do not worry. I will try to fix the issue.

let's try these steps: 

Adjust the display brightness using the keyboard function keys

Adjust the screen brightness using keyboard keys. The brightness function (fn) key numbers (f9 or f10) might vary depending on the notebook model. However, the icons on the keys should be similar.

To make the display brighter, hold the fn key and press the f10 key  or this key  repeatedly.

To make the display dimmer, hold the fn key and press the f9 key  or this key  repeatedly.

Brightness adjustments on some notebook models do not require pressing the fn key. Press f2 or f3 to change the setting.

NOTE: If you restart the computer after adjusting the display brightness, the brightness level might return to the default setting based on the power source (battery or AC). This is not an error; the notebook is functioning as designed. Use the function keys to change the brightness back to the desired setting, or change the default settings in the Control Panel.

Adjust the display brightness in Windows

Open the computer power plan settings to change the screen brightness.

1. Search Windows for 'edit power plan', then click Edit power plan in the list of results.
2. Use the Adjust plan brightness sliders to increase or decrease the screen brightness, then click Save changes.

Connect the AC adapter while the notebook is turned on

To adjust the brightness of the display using the battery setting, connect the computer to AC power while the notebook is turned on and using the battery. Battery power option plans have brightness settings that can be customized. This might explain why the display is brighter when AC power is used. If the display is brighter when plugged into the AC power, unplug the AC power to check the battery brightness settings.

Check for display driver update in the Device Manager (Windows 10)

Windows Update will automatically load the correct drivers upon upgrade. If the correct drivers were unable to be installed on upgrade, you might need to manually update the graphics driver using Windows Update following these steps:

1. In Windows, search for and open Device Manager.
2. In the list of devices, expand Display adapters.
3. Right-click the graphics device and select Update Driver Software.
4. Click Search automatically for updated driver software.
5. Follow the on-screen instructions to install the updated driver.
6. Restart your computer to complete the installation of the updates.

Hello. Thanks for your reply. However I've performed all the tasks you mentioned with my laptop and the issue still persists. Windows 10 does show an Optional Update, something about Hotkey support but when I try to install it, it finishes very quickly and when I check for updates again it shows up as an optional update again. I've attached a screenshot. I have a feeling this is somehow connected to my issue.

@michaelseko1992,

Yes, Check the box and click download and install 

[michaelseko1992]

As I stated in my reply, I already tried that. It doesn't fix the issue and it keeps coming back as an available update when I check for updates again.

Hi@michaelseko1992,

We have done the basic troubleshooting as per the document and the notebook needs to checked taking remote access so that get to know it's a hardware or software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.

I will contact the support team, especially since I still have 4 months left on my warranty. Thank you.
