I have a HP envy m6 notebook and when im viewing websites the brightness will keep randomly changing. Why is this and how do I stop it? I've gone into the settings and turned off the 'enable adaptive brightness' but it still seems to keep happening.

View 1 Replies View RelatedI 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.

possible ways to adjust one's screen brightness within windows 8 on a laptop?
for some odd reason the laptop only adjusts the brightness when on the battery and it does that intelligent adjustment crap(tried to find a more polite word....failed).
So, a few days ago the battery of my laptop died and when I charged it and power it up again I found that I can't change the brightness of my screen which I was able to few minutes before. I tried fixing it by going onto control panel>hardware and sound>power option, but it didn't work. It's just stuck. What can I do? Is my laptop broken?
View 9 Replies View RelatedI 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).
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?
I have: Turned off adaptive brightness, told it to never dim the screen at any time for any reason under any battery plan, and still, right-on-the-dot, at exactly 1 minute, my screen turns off.

View 4 Replies View RelatedWell 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.
View 2 Replies View RelatedI 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.

View 8 Replies View RelatedI 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?
I bought Dell 5521 2weeks ago (8gb ram 1tb hdd i5 1.70ghz). Whatever, now, i can't use my FN+F4/F5 keys. I can't control/change my screen brightness. Other Fn keys are normal. I can use them but just i can't use my brightness. What should i do? A person said me that "download the Fn key's driver" but i don't know which driver is.

View 4 Replies View RelatedWhen I leave my computer for an extended period of time, after returning the screen is sometimes blank. I know that everything is still on, the screen just won't come on. I know things are still running in the background because when I restart my computer by pressing the reset button (the only thing that works), when I boot back into Windows a few seconds later and relog into an IRC channel I was in before, my old nick gets ghosted. If my old nick was still in IRC this means my computer was still on and working fine until I hit the reset button - screen being blank was the only issue.
I've tried multiple things, such as hitting the "wake" button on the keyboard. I've checked my power settings carefully, modified them, but still no luck. There doesn't seem to be any pattern to this behavior, it either happens or it doesn't, and the time period it takes for it to happen seems random. Browser session auto-recovery.

I have spoken with windows support... I used to have an option on my taskbar to adjust the screen size. They have no idea what to do. I can go through my computer and set the screen size to 100 % but if I am tapping while on the net it changes dramatically and I don't know how to control the overall size. It seems my upgrade to 8.1 has created more problems

View 3 Replies View RelatedI have an asus laptop and i have a problem with increase and decreasing level of brightness.
my operating system is windows 8.1 and i download and installed latest version of driver that is compatible with my OS. when i early installed windows, i installed drivers and don't have problem with it. but now after months suddenly it happened to me.
i can see OSD that changing brightness, but i don't actually see any change
what the registry key (or other option) was for the incremental brightness steps.
I am trying to figure out if I can lower the amount that my brightness changes in each "step" or click of the brightness function key. I know for a fact my display supports changing the brightness in smaller increments (You can do it with the slider in the battery settings) I just need to figure out how to change the amount that Windows increments/decrements per key-press.
I've installed windows 8 and I was able to change the screen brightness without any issues. After installing windows 8.1 however, I wasn't able to change the screen brightness. I was only able to change it when using the standard windows graphics driver, but when using the AMD driver it won't work.

View 3 Replies View RelatedObviously there is no doubt that the n150+ or any Samsung note/netbook have had problems with not being able to control their devices brightness on Windows 7. This is because any driver after the OEM driver would change a particular number in the registry(regedit)
There were two fixes to this problem in WIndows 7. The simple way was to install the original VGA driver. The other was to change a specific number to 84 in the registries.
I have tried both and still can't adjust brightness with the fn keys. I've installed Easy Display Manager which is the software required to use fn key functions. Sound works automatically with or without the software.
I'm wondering why I can't get this to work.
I've noticed that whenever I unplug my charger my brightness dims down to a point where I know its on, but I can't use it. Usually I have to put my computer to sleep and turn it back on to get it to fix. Also, the brightness wont adjust in anyway when its on. I've tried the function keys and the setting in the side bar. I have a toshiba laptop running windows 8.1 . I also have recently completely wiped it thinking it was a virus of some sorta with no change.

brightness goes to minimum as soon as i start my system and then i can't increase it using any settings . I can increase it sometimes using keyboard , but that is temporary . Also whether it is plugged in or not , that thing doesn't change the problem.
