I have a problem with the brightness on my HP Pavillion G7 Laptop. Please, can you advise me how to fix the problem?

Please can you advise me to fix the problem?

If you want to adjust the brightness on almost any Laptop, you need to change the power settings. The display on a Laptop goes dim to conserve energy. Most likely go to the taskbar and click the battery icon. It should give you an option to adjust the performance settings. If it is not there, it should give you an option to go into the power settings menu. Here you can set the brightness for the Laptop when it's plugged in or unplugged.

It did not restore the brightness on my Computer. What should I do?

The above steps are the solution for your ASUS Laptop brightness issue after the update on your computer. If the steps did not work for you, try to restart your computer and boot into Safe Mode and try the steps again. Hopefully, this will resolve the problems you're having. Another thing you can try is a System Restore on your computer. You might lose some files by performing a System Restore. Restore your computer to a date before the issues showed up. This should restore the brightness back to your computer screen.

If the suggested steps did not resolve the problem, there are combination keys that you can press to perform shortcuts to adjust brightness and so on. Most laptops (including some models of ASUS) have these keys. Look for the Fn button and check your Laptop keys, as they have sub-options for you to adjust some settings, such as volume or the brightness.
