How to Increase Laptop Screen Brightness in Windows 7

Change the power plan brightness for a laptop running Windows 7.
By

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:

  1. Go to Control Panel -> Hardware and Sound -> Power Options.
  2. Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver). 
  3. 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.
  4. 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.

Doug,
I have exactly the same problem on a toshiba laptop after installing Windows 7 yesterday. but when I go into the Control Panel there is no brightness slider and no 'Adjust Plan Brightness'. Restoring the default settings has no effect at all, when on battery or mains. Any further ideas?

Hey Aidan,
There's probably some sort of video driver issue. I'd recommend updating your drivers. Also you should try installing the TOSHIBA Value Added Package for Windows 7. Download it here: http://www.csd.toshiba.com/...

Check for compatibility here: http://www.microsoft.com/windows/compatibility/win...

From the looks of it, the TOSHIBA Value Added Package for Windows 7 has a Power Saver feature that provides various power control functions unique to TOSHIBA. See pic here: http://jkontherun.com/2009/10/21/toshiba-updates-n...  Hope that helps, let me know if it solves your problem.

Hi Doug, thanks for your help. It turned out to be really simple. When the first lot of Windows updates came through the problem was solved - on reboot the screen immediately changed to full brightness, and the brightness function keys started to work.
Great! I'm glad to hear you got things working!
