So I can't find the screen brightness slider or any brightness adjustment option in my power plan options. All I can do is determine when to put the laptop to sleep and when to turn off the display.

It seems like the common solution for many was to go to Device Manager and uninstall the driver under Monitors, then scan for hardware changes. I did that and it didn't work. If it helps, under my Monitors section it says "Generic PnP Monitor".

Update: I've since found a semi-solution. I can adjust the brightness by holding the Fn key and pressing up/down on my arrow keys. However, the brightness sliders are still missing.

  • What kind of monitor / Video Card? Is this an OEM Utility like from HP or Lenovo? That maybe the issue.. – Leptonator Jan 27 '14 at 6:54
  • Not so familiar with this stuff. What do you mean by the kind of monitor? The laptop I'm using is a Dell Studio XPS. – user3201152 Jan 27 '14 at 6:59
  • Did you install Windows yourself or did it come on the laptop? An OEM (Original Equipment Manufacturer) like Dell does have the ability to distribute Windows as part of a package with systems they sell. – Leptonator Jan 27 '14 at 7:03
  • The laptop was a gift so I don't know what it started with, but there's a sticker that shows Windows Vista on it, so I'm gonna assume Windows did come with the laptop and Windows 7 was later installed on it. – user3201152 Jan 27 '14 at 7:10
  • See the response.. Is that the slider you refer to? If you go to a customized power plan, you may see some odd things.. What about going to default power plan? – Leptonator Jan 27 '14 at 7:15

If it is a laptop, it will most likely come back if you reinstall manufacturer's management tools software. The are usually full of unwanted stuff, but if you uninstall them, those on screen goodies like screen brightness indicator will go away too.


I have been having the same problem and I just found out a really easy and fast way to find the slider. It wont even take a minute.

Just go to control panel, then hardware and sound, then power options. In the power options window, wether you use the balanced or power saver plan, you will find a "change plan settings" button.

Press that, then below the display adjustments, press the "change advanced power settings". A little box will appear, and you will find a "change settings that are currently unavailable" button. Press that, and then scroll down until you find display. Click on the plus sign on the left side of it, then click the plus sign of the "Display Brightness". From there you can adjust it to your liking. Hope that helps. Best of luck to all of you, Contributer

  • I did what you said, and even that option is missing! i.imgur.com/soRemk8.png Anyway, I've since found a way to adjust the brightness. I can just hold the Fn key and press up and down on my arrow keys. But all traces of the brightness slider are still gone. – user3201152 Nov 7 '14 at 8:16

Never mind - I see the slider you talk about..

Here - Slider

It is in the Power Plan information.

I am sure it is in Control Panel too.

  • That would be screen resolution, hes after brightness. Its likely under power settings. – Nathan Kerr Jan 27 '14 at 7:10
  • Yep.. I realized that right as soon as I was posting it. Updated to show the brightness sliders he is talking about. – Leptonator Jan 27 '14 at 7:13

    My problem is that it's mysteriously not there. Mine looks like that but without anything related to brightness. i.imgur.com/QuAXlk2.png – user3201152 Jan 27 '14 at 7:15
  • Do you know when this disappeared? Like 1 or 2 days ago? What about restoring your system to that point? – Leptonator Jan 27 '14 at 7:19
