Cannot Change Screen Brightness In Windows 8.1?

Jul 4, 2014

I just yesterday finished my new computer (16Gb RAM, i5-4470k, GTX 770, Win 8.1, etc.) and I just today realized that I cannot change the screen brightness. The button is grayed out and says "Unavailable" which I know cannot be possible.

Now, i have done my research and people say that the fix is to update your drivers through the Device Manager, and I have tried that to no avail. I have tried all possible combinations of "Display Adapters" and "Monitors" drivers. None work. I have been restarting my computer after every change .

One thing that I might add is that a lot of people remedy this problem by reverting their Intel Integrated drives back to an older version, but I do not have an option to change it's drivers. It shows up nowhere in the Device manager.

My eyes are burning as I am typing this and I would even go for a third-party brightness program (if that even exists).

HP Recline 23 / Windows 8.1 - Cannot Adjust Screen Brightness

Jan 25, 2014

I have a new computer , HP recline 23 . OS is Windows 8.1 . It came out of the box with Windows 8 , so I had MS store update to 8.1. The screen is set very bright , OK for day use but too bright for night use .

My problem is that I can't adjust the screen brightness. After clicking on the charms menu and clicking on settings , the brightness icon is greyed out . It says windows cannot adjust brightness on this computer. I tried the various locations where the brightness slider may be but all the relevant screens show no brightness slider.

I don't know whether win 8 had the brightness control before upgrading to 8.1 ( I mention this because several people complain that after upgrading to 8.1 , they loss brightness control amd regained it by rolling back the driver )

I tried the update driver option but it says my driver is already updated. The roll back option is greyed out ...

BTW the display adapter shows two adapters : Intel 4600 and Gforce GT730 . How do I check which one is being used?

Windows 8.1 Toshiba Satellite - Unable To Adjust Screen Brightness

Aug 24, 2014

I have a Windows 8.1 Toshiba Satellite L875D-S7332, with a AMD A6-4400M APU processor with integrated graphics. My display adapter, according to device manager, is a AMD Radeon HD 7520G.

Now, my problem is that I'm unable to adjust the screen brightness of my laptop. I haven't made any recent changes, and I noticed this about a week or so ago(I don't typically change my laptop brightness, so this could have been happening for longer). In the mean time, I've tried rolling back my display drivers, with no success, and also updating to the latest driver set, which has also not worked?

Screen Brightness Will Not Change?

Dec 16, 2013

I have tried to change my screen brightness for the first time since downloading windows 8.1(about a month ago) and it is stuck a the lowest level. I have used the keys, the settings, and even the "Adjust screen brightness" button after clicking on the battery in bottom right of screen. I looked at my drivers and checked if my "Display adapters" needed to be updated, it didn't.

Hardware Drivers :: Screen Seems Dim - Brightness Won't Adjust

Jun 7, 2014

Well I've had my laptop for almost 5 months now, however I did break it and got a screen replacement yesterday. Ever since then my screen seems dim. I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem. I had no trouble altering my brightness before my screen replacement so I do presume that the screen that the shop fitted wasn't the correct one and therefore a cheap option.

Hardware Drivers :: Laptop Screen Brightness Won't Adjust

Oct 18, 2013

I went and bought a new laptop since my old one was starting to die on me and stuff. It's a Samsung ATIV Book 4, and it's really nice. This is the first hick up I've had with it so far, and I noticed it happening today. I noticed my screen was really dim today as I was using it, so naturally, I use the Fn key to turn it up, but nothing happens. Up in the top left of the screen, it shows a little brightness meter going up and down as I turn it up and down, but nothing changes. I went to the power options menu and tried to adjust it there, and alas, nothing happened. I even tried disabling the display driver and restarting it, but that didn't do anything.

Windows 8 Laptop Turning Itself Off?

May 24, 2013

I am currently running with a HP 15.6" Envy Laptop PC, Midnight Black, dv6-7229wm - I have not had problems before. While I was playing Diablo 3, on medium settings, the thing just cut out. The first time, i didn't think anything about it. I turned it back on, and it turned off again twice during the HP boot logo. So i took out the battery, waited a little and started playing Diablo 3 again, and in about half an hour it turns itself off again. Each time it turns off, there is the pop of the audio going out. So, i turned MSI after burner on (I have not over clocked this system, I just have MSI to watch the heat when I was messing around one day)

Anyway, here are the last three temperature logs from MSI afterburner before it turned itself off.

02, 24-05-2013 15:09:13, GPU1 temperature ,GPU2 temperature ,GPU3 temperature ,GPU1 usage ,GPU2 usage ,GPU3 usage ,GPU1 core clock ,GPU2 core clock ,GPU3 core clock ,GPU1 memory clock ,GPU2 memory clock ,GPU3 memory clock ,GPU1 memory usage ,GPU2 memory usage ,GPU3 memory usage 80,

[Code] .....

The log isn't coming out how I wanted to, but it was about 95-99 for all of it. I am playing on a table (As level as a table can be on a 40 year old brick floor), with nothing anywhere near the laptop.

PC Is Not Turning On After Playing Battlefield 4

Feb 21, 2014

I was playing Battlefield 4 for about 15 minutes, after I was finished I closed the game and my PC just died, as if I got a blue screen without the actual blue screen, fan speed of psu went to max and stayed that way until I restarted it multiple times, none of those times did it actually boot or display anything on the monitor.

Now when I start up my pc it turns on but nothing happens, display doesn't even come on and keyboard and mouse light up and turn off again.

Security :: Avast Turning Off USB Ports

Mar 23, 2014

Problem with Avast turning off USB ports?

After weeks of stable computer use, I tried using Avast once again, but I noticed when I restarted, my USB mouse no longer worked. I moved it to another USB slot and it worked, so I didn't worry about it.

Then today, I noticed that the two front USB slots on my computer weren't reading anything. I remembered this problem started when I started using Avast, so I uninstalled Avast and presto, I regained usage of my USB ports upon reboot.

How to keep AVAST from turning off the ports? I couldn't see anything on google offhand. If not, I may just go back to Windows Defender.

Laptop Going Into Standby Instead Of Turning Off Display

Nov 9, 2013

I've upgraded to windows 8.1 a few days ago through a custom install as I was running windows 8 x86 and wanted to switch to x64. I've also just updated the BIOS.

After the upgrade though, my laptop goes into sleep/standby and locks the screen instead of turning off the display as I have it set. So, if I edit any power plan settings to turn off the display after 2 minutes, it will go to sleep after 2 minutes.
