How to Increase Laptop Screen Brightness in Windows 7
Change the power plan brightness for a laptop running Windows 7.
Saturday, November 7, 2009
I recently upgraded to Windows 7 Home Premium on my Dell Inspiron laptop. After using the laptop for a few days, I noticed that the screen display brightness was much dimmer than what it had been when Windows Vista was installed on the laptop. To solve my screen brightness issue I found that is was simply a matter of adjusting the power plan brightness within the 'Power Options' of Windows 7.
Here's how to adjust the screen brightness for a laptop in Windows 7:
Go to Control Panel -> Hardware and Sound -> Power Options.
Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver).
Now edit your plan settings by moving the sliders next to "Adjust plan brightness" at the bottom. You'll be able to change the brightness for when your laptop is On battery power, or when it's Plugged in.
Once you've adjusting the brightness settings to your liking, then click on the 'Save changes' button.
Note: You can also restore the default settings for Windows 7 power plan. Follow the same steps above to get to the Edit Plan Settings page. At the bottom of the page click on "Restore default settings for this plan", then in the Power Options pop-up box, click 'Yes'. When I did this it adjusted the brightness settings for Plugged in to the maximum, and On battery brightness to just under half on the brightness slider.
