Other times, though, it could be an issue with the lighting. Another problem occurs when a screen dims and brightens by itself, randomly.

Something like this can happen due to corrupt display drivers on your computer, and not necessarily because of a faulty battery.

Before using any of the solutions below, check the following things:

  • The make and model of your laptop
  • Whether you made any software or hardware changes prior to the laptop screen issue

This is important to note because laptop screen dimming/brightening issues may occur if power settings are corrupt or incorrect.

In case your laptop issues persist, we created a list of several solutions that can easily help you solve the screen problem.

How can I fix the screen dim and brightens issues on laptops

  • Update latest ACPI drivers
  • Use Power troubleshooter
  • Check your laptop screen display settings
  • Update display card drivers

1. Update latest ACPI drivers

  • Right-click on Device Manager open Properties and select details.
  • Use the pull-down list to find the hardware identity (IDs).
  • Copy the short string and search for it on Google.

When you find and download the driver from its manufacturer’s website, remove the current one, then uninstall it completely. Install the fresh copy of the driver once you remove the old one.

Updating the drivers manually can cause a lot of problems on your PC if the wrong ones are being installed.

Having this in mind we strongly suggest doing it automatically by using dedicated software, such as DriverFix. After several tests, our team concluded that this is the best-automatized solution.

The software is very easy to use, and its interface is extremely intuitive. All you need to do is run the program and allow it to start scanning your PC for outdated drivers.

Moreover, DriverFix will compare your existing drivers with the ones found in its built-in database and fix them if broken

When the scan is completed, you will also get a report with all the faulty drivers that have been found on your PC. Next, you can choose if you want to update them individually or all at once.

2. Use Power troubleshooter

  • Right-click Start and select Control Panel.
  • Go to the top right corner and change View by option to Large icons.
  • Click Troubleshooting.
  • Click on View all option on the left panel.
  • Click on Power.
