Understanding the Brightness Keys on HP Laptops
Before we dive into the troubleshooting process, it’s essential to understand how the brightness keys work on HP laptops. The brightness keys are usually located on the top row of the keyboard and are marked with a sun symbol.

Common Causes of Non-Functional Brightness Keys
There are several reasons why your brightness keys may not be working on your HP laptop. Some of the most common causes include:
The brightness keys may be disabled in the BIOS settings or the operating system. This can happen accidentally or due to a software update.
A driver issue can also prevent the brightness keys from functioning correctly. Outdated or corrupted drivers can cause conflicts with the keyboard and display settings.
A hardware problem, such as a faulty keyboard or a malfunctioning display, can also be the culprit behind non-functional brightness keys.
In some cases, a software conflict or a virus can interfere with the brightness keys’ functionality.
Troubleshooting Steps to Fix Non-Functional Brightness Keys
To resolve the issue with your brightness keys, follow these troubleshooting steps:
First, restart your laptop and press the F10 key repeatedly during boot-up to enter the BIOS settings. Check if the brightness keys are enabled in the BIOS. If they are disabled, enable them and save the changes.
Next, update your keyboard and display drivers to the latest version. You can do this by going to the HP website, searching for your laptop model, and downloading the latest drivers.
If updating the drivers doesn’t work, try resetting the BIOS settings to their default values. This can be done by pressing the F10 key during boot-up, then selecting the “Default Setup” or “Reset to Default” option.
Additionally, scan your laptop for viruses and malware using an anti-virus software. This can help resolve any software conflicts that may be causing the issue.
