brightness issues

[vb201]

My HP Envy x3600 Laptop Ultra 7 intel core, is not increasing or decreasing the screen's brightness. It will sometimes automatically get super dark, making it hard to see. Sometimes it will go brighter, and even putting the brightness down it wouldn't go down.

Hi @vb201,

Welcome to the HP Support Community. 

I'd be glad to help you! 

The issue you're experiencing with your HP Envy x360 laptop's brightness control can often be due to software or driver problems. Below are several steps you can follow to troubleshoot and fix this issue:

1. Update the Display Drivers:

• Go to Device Manager by right-clicking the Start button and selecting it from the list.
• Expand Display adapters, right-click on your display adapter (likely Intel or NVIDIA), and select Update driver.
• Choose Search automatically for updated driver software. If there’s an update, install it and restart your laptop.
• Alternatively, you can download the latest drivers directly from the manufacturer's website (Intel, NVIDIA, or AMD).

2. Check Power and Sleep Settings:

• Go to Settings > System > Power & sleep.
• Click on Additional power settings.
• Choose your current power plan and click on Change plan settings.
• Click Change advanced power settings and look for Display settings. Ensure that brightness settings under both On battery and Plugged in are set correctly.

3. Disable Adaptive Brightness:

• Adaptive brightness can sometimes cause the screen brightness to fluctuate automatically.
• Go to Settings > System > Display and check if there’s an option for Change brightness automatically when lighting changes. If it’s on, try turning it off.
• Alternatively, in Control Panel, go to Hardware and Sound > Power Options > Change plan settings > Change advanced power settings. Under Display, look for Enable adaptive brightness and turn it off for both On battery and Plugged in.

4. Update BIOS and Chipset Drivers:

• Sometimes the BIOS or chipset drivers can affect screen brightness functionality.
• Visit the HP support website and download the latest BIOS and chipset drivers specific to your laptop model.
• Install the updates carefully following HP's instructions, as BIOS updates should be performed with caution.
