Update Your Display Drivers

Before we dive into the fixes, make sure your display drivers are up-to-date. Outdated drivers can cause various issues, including brightness control problems. You have two options to update your display drivers:

Option 2: Update via Device Manager

Open the Device Manager, go to Display Adapters, right-click on the graphics driver you want to update, and select 'Update Driver.'

Other Possible Causes

If updating your display drivers doesn't solve the issue, there are other factors that might be contributing to the problem:

* Hardware Malfunction: Faulty hardware can cause brightness control issues. Make sure your laptop's screen is not damaged or malfunctioning.

* Software Configuration: Misconfigured software settings can also cause problems with brightness adjustment. Check if any third-party software is interfering with the system settings.

* Power Issues: Ensure that your laptop is properly charged or connected to a power source. Low battery levels or power-saving modes might be causing the issue.

Fixes

Try the following fixes to resolve the issue:

1. Adjust the monitor settings: Check if the Lenovo monitor brightness is locked mistakenly while using an external monitor.

2. Charge or connect your laptop: Ensure that your laptop is properly charged or connected to a power source.

3. Disable and re-enable the graphics driver: Sometimes, disabling and re-enabling the graphics driver can resolve the issue.
