A Fix For Problems Adjusting Laptop Screen Brightness

At times, laptop users may have problems adjusting laptop screen brightness, where the system does not respond to the brightness changes. More specifically, the laptop screen brightness cannot be adjusted until the system is restarted or rebooted. Here are solutions that may work for some users.

Problem Adjusting Laptop Screen Brightness

Laptop users may have found that sometimes when they try to adjust the brightness of the laptop screen, it doesn’t work.

Whether using the keyboard or adjusting settings through the power options in your control panel, the brightness setting is shown to change, but the actual screen brightness does not change.

This may happen after resuming your computer from hibernation or sleep mode.

Solution To Adjust Laptop Screen Brightness Again

For some, changing the Windows power settings may be the solution, so it is possible to adjust your laptop screen brightness again, without rebooting.

In the Windows Control Panel, go to Power Options. Under the Advanced Settings, scroll down to “power buttons and lid”. Under “lid close action”, change the settings for “on battery” and “plugged in”, so they both are set to “do nothing”.

Hopefully, that solves this screen brightness issue for you.

Alternative Solutions

Some alternative solutions that may work for some users include opening/closing the laptop lid, uninstalling/reinstalling the monitor, hibernating/resuming the system, and installing a new monitor driver.

Also, if you restarted your system, then you should be able to adjust the screen brightness properly once again. But of course, that’s not the preferred method, just to be able to change your laptop’s screen brightness.
