New laptop not adjusting brightness

Q: New laptop not adjusting brightness

Hi all,

Last tuesday I've received my new laptop / netbook: Asus X205TA. After installing everything I found out that my brightness isn't adjusting. I've tried to:
- Use all different ways to adjust brightness (charms bar, shortcut, power plan settings etc.)
- Windows update
- Update Microsoft Basic Display Adapter drivers (there are no updates available)
- Disable and re-enable the Display Adapter

Yet: it's not working. I've also have a problem booting up games. Even the simplest of games (as the netbook is low-spec) are either not booting up, or they show errors about not being able to access the video card or so. I wonder whether these issues have something to do with the brightness settings.

I'd appreciate any input from you guys

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Well issue is that your graphics cards drivers are't installed, nor detected! So you are stuck with Basic Display Adapter Drivers

I had a look at the specs and it says "Integrated Intel? HD Graphics" which isn't helpful as there are different models of the Integrated Intel? HD Graphics

I have a NIVIDIA RIVA TNT2 MODEL 64P monitor with Windows XP installed. The brightness, color etc. on the monitor seem to be at the max but all images/pictures/movie files etc are very dark. Is there any other way to adjust the brightness on the monitor?

A:Adjusting Monitor Brightness

I think that's just your video card type. If your monitor is old and this has been gradually getting worse then it could be going. You can usually adjust the brightness with your video card settings.

Right click desktop, choose properties, settings, advanced. You may have to try a few of the tabs to find the controls.

I've recently got a new computer laptop with Windows 7 and the first thing I noticed that the screen is much brighter (and maybe more saturated) than my previous laptop (with Windows XP). First I thought it was my laptop, but then I saw an other computer with Windows 7, and the screen there is very bright too. I searched the net and I see that there are more people complaining about the brightness on Windows 7.
I understand that I can set the screen brightness, but it seems like a fact that the "default" brightness on Windows 7 is way brighter than on Windows XP. Some people are probably accustomed to this, but to me it's too much. I can decrease the brightness with the laptopl's controls on the keyboard, but I think that's not the way to go - I think I should look at the Windows 7 configuration. I could go to the ATI Catalyst, but is there an other way? Is the Calibration tool the only option?

And the second question, if this is a common problem, maybe there are some known settings that would take Windows 7 brightness closer to Windows XP and earlier versions?

A:Adjusting Windows 7 brightness - what's the best way?

If these are new laptops then, yes they will be brighter then older computers. But it has nothing to do with Windows. It has to do with the display themselves. A lot of the new LCDs on modern laptops are brighter quite a bit brighter then previous generations in part, moving to LEDs for the backlight.

I recently upgraded from WIN98SE to WINXP. Before the upgrade I used to go into my Display settings to adjust the brightness on my monitor through the video card, but now through XP I cannot find that function. My video card is a Nvidia Riva TNT2 64MB card. I have a brightness adjustment in the monitor settings, but that is already adjusted at 100% and I need to adjust up a little bit more. Does that make sense? Does someone know where I can find this now that I am on XP?

A:Adjusting Brightness in Display Driver

Uninstall your NVidia display adapter. Run one of these to be sure all the driver files are removed: Driver Cleaner Professional or Nasty File Remover.

Then, install the most recent driver:


You'll find color, brightness, gamma adjustments in the advanced display properties and a separate adjustment for DirectX overlays, such as video player windows.

Hi there guys,

I have a problem with my dell inspiron m301z laptop,
Whenever there is something dark on my display ( this could be a picture or a website or something else) my brightness automatically adjusts to that environment. So its like the brightness is adjusting automatically depending on the virtual environment. I looked up the forum for similiar problems and tried some things with the power options and stuff but couldnt not fix it..

However this does not happen when the adapter is plugged in, everything stays equal all the time,

Thank you guys.

I just got the HP Pavilion 27xi IPS LED Backlit Monitor at work, working on a computer running Windows 10. I'm pretty tech-saavy, but I cannot figure out how to adjust the brightness! I've tried the F9/F10 function; doesn't work. I then thought it might be an issue with the driver, so I went to Settings -> Displays -> Advanced Display Settings -> Display Adaptor Properties -> Monitor (tab) -> Properties -> Driver (tab) -> Update Driver but got the "The best driver software for your device is already installed" message. Under the Settings -> Displays screen, there's no option for adapting the brightness and I've scoured the forums, but none of the solutions presented are working. Should I manually install an older version of the driver software? Any other potential solutions?

Hi All,

I have an ASUS S400CA running Windows 8.1 (64 bit) and I am having a major issue. When I click Fn + F5/F6 to increase or decrease the brightness, nothing is happening. The slider is stuck beyond a point and the brightness does not change regardless (it is stuck at the highest setting). I have tried to fix this issue by changing brightness settings in the Control Panel, Battery Options, etc. but nothing is working.

How do I fix this issue? Is this is a driver issue? I have tried to find previous versions of the Intel HD Graphics 4000 Driver on the Asus website but only find the one I am using. What should I do? This is urgent!

Thanks so much!

Hi everyone, I have a pretty weird tech problem.

What happens is, whenever I adjust my monitor's brightness (from its physical buttons) the screen turns black. However the monitor is still on, the LED is still green and the computer is still responsive, the screen just turns black.

I can use the computer just fine, as long as I don't try to adjust anything. If I do want to change something, I have to change the values a little, then restart, change them again, restart until I have the values I want. This problem appeared when I tried to adjust the brightness by keeping the + button pressed down, so it increased quickly.

Is this indicative of a dying monitor ? It is pretty old, it's an LG L1750SQ, 17 inch LCD, it's over 4 years old. Also, I do not believe the video card to the problem, since it stays pretty cool, it has a good heatsink on it.

Yesterday for no discernable reason the contrast changed on my HP laptop (G62) and I can't find any way to adjust it back. I run Windows 7 if that's relevant. There are no function keys on the laptop for contrast, only brightness, which doesn't do the trick. I've been in the control panel / display menus to no avail and googled for a solution but found nothing . . . very frustrating.

Hi and thanks for taking the time to read this.

I have been getting the BSOD frequently in the last week and could not figure out if it happens when I use a specific programme. Today I realised it happens regardless of programme, when I adjust the lid to avoid reflections. It also does it when I close the lid without shutting down the laptop.

I am far from an expert in computers but after reading around the site I think I have managed a) to activate the driver verifier and b) to get the DM log collector report which I am attaching here.

Hope you can help!
Thanx in advance

Very similar if not identical to this thread: whenever I adjust the volume on this Toshiba Satellite A135 laptop using the analog dial on the front of the machine, Windows Explorer crashes. Also, the Speaker Properties window in the Control Panel will crash if I click the Levels tab. This only started happening since the upgrade to Service Pack 1 of Vista. (This machine runs Vista Home Basic, and just fine before the upgrade).

Probably a driver issue, I know, but Toshiba doesn't seem to have released any audio driver updates. Driver version installed is Realtek High Definition Audio, from 11/8/2006.

Anyone else have this problem, or hopefully maybe even a fix?

I have a Lenovo laptop. When I turned it on this morning, the brightness of the screen was very low. I went to settings to increase the brightness thinking maybe it was turned down....it was not. The brightness showed max. So I moved the brightness scale up and down to see if there was any change in the brightness. No change occurred at all. Even moved to the lowest my screen stayed the same. I shut computer down and turned back on. Still low brightness. Went into settings again to move the brightness scale. Same thing. No change at all. What else can I do because I can barely see my screen.

Below is insert from the help menu, but when I press on the FN button, nothing happens.

You can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness ( ) or increase brightness ( ). When using Display Color Calibration on a laptop, set the display to the maximum brightness setting.

A:How to change brightness on my laptop?

You must hold the FN key down and press one of the F keys (top row) at the same time, I think it's F9 and F10 to change the brightness on HP laptops, there will probably be a 'sun' symbol on the key with up or down arrows.

I have an Acer Aspire 8930G with Windows 8.1 x64 and Windows 7 x86 as a dual-boot. I use 8.1 as my everyday OS and only boot into 7 to play older games that only work with a 32-bit OS.

Ever since I installed Windows 8, I have not been able to adjust the brightness of my screen. Note that this problem started since I installed 8, not 8.1, and before I put on the copy of 7 as a dual-boot. When I use Fn+left/right (the brightness keys on my PC), the brightness slider appears on-screen and goes up and down, but the brightness of the panel doesn't actually change. Using the Charm doesn't help either, nor does adjusting it through the Control Panel.

I have tried fiddling with my Power Options in the Control Panel and disabling adaptive brightness. I have tried several different driver versions for my GPU, a GeForce 9600M GT. None of this has helped.

In Windows 7, however, the brightness controls work fine. If I want to adjust my brightness for 8.1, I have to boot into 7, change the brightness there, and then boot back into 8.1, where it will keep whatever brightness setting I was using in 7.

Does anyone have any ideas on how to fix this? Is there some messed-up thing in the Registry? Is my GPU's firmware maybe just not compatible with Windows 8? I took a look at TechPowerUp's repository of GPU BIOSes, but it appears I already have the most recent one.

If you're using any sort of third party software to help control the brightness of your screen, you should uninstall it.

Stick with the function key on your laptop and Windows.


Click Start.

Click Control Panel.

Click Power Options.

There should be a slider at the bottom of this window which will allow you to adjust your brightness if the FN key(s) are giving you trouble.

I purchased my Dell Inspiron 15 3537 laptop a year ago and up until recently it had worked fine, however recent problems i have encountered have been as follows:
-If i close the lid or use any other method to try to put the laptop into sleep mode the screen will turn off, as normal, but it cannot be woken by any means, requiring a forced shutdown then restart.
-If the laptop is left to idle to long and the screen turns off, but not to sleep, the same situation as above occurs.
-Sometimes, but not every time, when the laptop is restarted it doesn't recognize any AMD graphics driver, or any AMD device which i assume means it cannot detect the card
-Sometimes, but not every time and seemingly not linked to the AMD problems, when the laptop is restarted I am unable to adjust the brightness of the screen by any means, the keyboard buttons do not work and the options usually found in the power options are no longer visible.
-I sometimes get a device manager code 43 for the Intel graphics HD family
-Intel i7-4500u core
-64 bit proccessor
-AMD Radeon HD 8850

I had these problems earlier in the year, and they were fixed with a factory reset, but one day while trying to play a game the laptop crashed and after the forced update these problems arose again. I called dell support to no avail, and I've searched for an answer but i cannot find it, likely due to my lack of technical understanding. If anyone can help id be grateful.
