I am not able any longer to change the brigntness of the display via the known keys if the light sensor is deactivated.
If the light sensor is activated I can adjust the brightness but I do not like the sensor.
I can change the brightness without the sensor when I am in the BIOS and during windows is booting.
My system: Precision M4500 with Windows 7 Professional X64
The problem also occours with a fresh and pure Windows 7 Installation ..
I am using windows 7 professional 64 bit, on 15 r014tu notebook.
In my system Screen brightness is not getting changed using F2 F3 Keys since i bought notebook, Im not even finding slider in control panel->Hardware and sound-> Power options->change plan settings.BIOS Version is: Insyde F.14, 3/19/2014.
Also I need below drivers:Intel HD graphics VGA:PCIVEN_8086&DEV_0A16
I have just bought the Flex 15. I looked at the power settings and set the brightness, but it is ignoring the settings and always either darker or brighter than I want it. It keeps flickering between being darker and brighter and it's giving me a headache. It is unplugged if that makes a difference, I haven't used it plugged in yet to know if it does it then. How can I stop it? I've looked through the settings and can't find anything.
I cannot adjust the brightness of my display using the Fn keys or the Control Panel... I have already had to replace my battery once... I need to be able to adjust the brightness in order save my battery life!
I changed my operating system from WINDOWS 7 ULTIMATE 32 BIT TO WINDOWS 7 ULTIMATE 64 BIT,and the problem is after changing OS my laptop is not displaying Brightness bar. Brightness is increasing and decreasing but it is not showing bright bar.
Any driver i have to install ? if required then driver download link.
I have a g6-2002au notebook, running Win7 home premium 64bit on dual core 64bit cpus, 2.7ghz clocks and an AMD Radeon 7520G gpu, that is mostly used to preview (for a class) movie projects created in a video editor. And for video project files - stored on a usb stick inserted into one of the usb ports - that have a playing time longer than approx 4 minutes, the play presentation runs for a while and then becomes stuttering - pauses the image for a while, altho the audio continues, then the video seems to catch up, and after a short period repeats this stop and go activity. Like the editor keeps running out of data faster than its work space is filled up.
I sourced equivalent (to the original brand and specs) RAM memory to increase the installed RAM to 8Gb without apparent impact on this. A change of memory stick type - usb2 to usb3 - worked a bit but the issue remains. And disciussions with others using notebooks - Toshiba's actually - did not have this problem.
The dedicated video memory in the machine is 512mb (windows display settings details), and this probably isn't enough for video editing. With 8Gb of RAM now available, there should be plenty to enable me to increase the amount dedicated for video editing. Changing that seems to be a bios function, but there isn't any apparent/accessible setting in the Insyde F.03 bios on the machine to enable me to do that.
So, the questions are, 1. Can I increase the dedicated video memory on this specific notebook? 2. if so, how?
I've recently bought an HP Probook430 and installed Windows 7 Ultimate 32bit and I don't seem to be able to change the display brightness, using the fn button+f9/f10 (although volume settings are changed in the same method smoothly).
Although the brightness settings don't seem to change, this bar does appear when pressing fn+f9/f10. What should I do in order to make the display brightness settings changable?
Everything had been fine until I did some updates, can't remember if this occurred after a video driver update or a BIOS update.
But now the display brightness maxes out at about half. When I hit Fn + up arrow, it starts off at about half and the little meter does go up (the sunshine puts on his shades), but the display brightness doesn't change at all.
My brightness function keys are not working. Other function keys like music player, mute etc are working fine in my windows 7 os. My Model no is 15-r006TU. I have installed all display drivers and checked action key settings in my BIOS settings. Nothing works.
The brightness on my HP 15-r018dx Notebook PC won't change, not using the function keys or the slider in "Power Options". This started happening two days ago; before then I had no issues. I am not sure what changed between then and now.
I have a HP Envy dv7 Notebook PC. It recently just downloaded the new HP Assistant and I wanted to adjust the brightness because it was too bright for the dark room I was in. I tried using the F2 and F3 keys to lower the brightness and I tried to adjust it from settings and control panal but the brightness doesn't adjust when I move it up or down. I tried shutting down my computer and restarting it but I still can't adjust the brightness.
Brightness is stable and the keys of btightness up and down are not working or can say that not changes the screen brightness. since so long and due to this the battrey backup is affacted..Having windows 7 ultimate 32 bit..
after some microsoft updates my Elitebook 8570W doesnt show me my brightness and volume bar anymore. sometimes when i restart my notebook he does show but after i plug in my BOSE portable via the headphone output he doesnt show it anymore (which he did before the updates).
i know you probably got this question alot and i searched a bit of the forum but couldnt quite get the right awnser. (and im not that familiar with HP but im quite confortable with).
Having problem with brightness some times brightness gets high and low auto. Mainly while watching movies. Also some times after turning on Laptop from hiberation it shows high brightness and if I try to decrease brightness it doesn't show any brightness level. My Laptop is under warranty.
I have a HP 1000-1405TU Notebook PC. My Notebook Product ID is D9H61PA#UUF. I am using Windows 7, 64 bit version. I tried using the F2 and F3 keys to lower the brightness and I tried to adjust it from settings and control panal but the brightness doesn't adjust when I move it up or down. (Note. When I use Windows 8 on this PC then there is no problem like that).
My product number is HP 1000-1312TU Notebook PC.And my os is windows 7 ultimate 64x.Since i've changed my os from 8 to 7 i couldn't change brightness of my screen neither with keyboard keys nor with power options setting, i mean they don't work at all.I also searched all the drivers.
I bought a dv3t-2000 two months ago and recently i installed windows 7 and i just realize that is not possible to change the brightness on the screen, is always the same. I have tried changing the power plans, I've upgraded the BIOS, but so far is not working.
This auto brightness problem is been bothering me for a long time now, and i can't find any fix for it at all. The display goes:
- Bright when having on screen a white web page, document, picture - and it display dims down when having on screen a dark web page/ document or picture
Note 1: I changed the settings and Turn off Auto Brightness in windows 8 advanced power plan settings .
Note 2: I tried to go disable the AMD Vari-Bright but the windows 8 AMD catalyse control center, but it doesn't have that option to turn in off .
Note 3: I did disable the Sensor Monitoring Service in services.msc menu .. but still didn't do the trick :/
Note 4: I did disabled Intel Display Power saving Technology in intel's graphic and media Control Panel and .. with all this, still, the auto brightness problem isn't solved :/
Now .. what to do, with all this attempts and still can't get rid of it, i start losing hope i can use my laptop without the screen changing brightness on its own, watching a movie and browsing the web with the screen flickers to adapter to the background....
