HP Envy Dv7 Display :: Why Can't Adjust Brightness Of Screen
Aug 20, 2013
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.
I just seem to unable to adjust the brightness of my screen. I tried restarting my computer, adjusting using f2/f3 or through settings it doesn't work?
My computer is HP ENVY 15-j175nr and my product numer is F7Q25PA#AB4.
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).
I m using HP Pavillion N208TX with windows 8.1 64 bit version. i m not able to adjust screen brightness from f2 and f3 button and from the power setting also. when i press these buttons it shows the slider to adjust the brightness on top left corner of the screen but its does not adjust the brightness from low to high. i have already updated the Intel HD Graphic driver...
I just bought HP 14-g003AU Notebook PC.. but i have stucked to adjust screen brightness.. I installed Windows 7 64 bit OS..
My adjust screen brightness is missing.. I have tried to download VGA driver (AMD Catalyst). But it doesn't work either..
Uninstall Generic PnP Driver Moniter and install again.. not work Uninstall Standard VGA Graphic Adapter.. and install again.. not work.. Try to update automatically Display adapter.. not work.. Update Windows 7.. Not work Reformat OS.. not work. Update LAtest BIOS.. not work ..
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!
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..
it's that friggin electric sound when you adjust your screen's brightness. Not that the sound is loud or anything but it's so annoying. Even clean install of mac os didn't help.
And it's not the hard drive that's making the noise. It seems to be coming from top left corner. Blackbook is half a year old and it started to emit that friggin noise a month ago. So did anyone had the same or having the same problem and did anyone removed this god dammed irritating sound !
I can't adjust screen brightness using either function key or in control panel. Using the function key the little panel of brightness volume shows up on the screen but does nothing. And in control panel, through either the bottom brightness scroll or the power option won't change anything. Only time when the brightness will change is I unplug the power, but in the power settings it won't let me change/adjust the brightness.
And what is the battery function key for? I press it and it does nothing. XPS L521x
I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again.
I have XPS 15 (L501x) laptop. I cant adjust the brightness of my screen through the function keys(quick set) or from Control panel (Control PanelAll Control Panel ItemsPower Options)I have already tried
Reinstalling quick set Restoring Reinstall Drivers from my Drivers CD Chipset : Intel HM57 Video drivers : Intel HD graphics
I also tried to install bios drives, but the system would allow me, saying, its already the latest
I have a W540 with 3K Ips panel and Windows 7 Pro 64bit.
I recently installed a new hard drive and installed windows 7 pro 64 (previously on the other hard drive was Windows 8.1 Pro 64 bit ( there I could change the brightness ) )
My problem is that I can not change the brightness .
I've already tried:
-Reinstalled all NVIDIA driver -Reinstalled all Intel graphic drivers new -Reinstalled Intel and Nvidia drivers simultaneously -Remove Lenovo Power management -Tried to install NVIDIA driver from the Lenovo and the Nvidia page -Reinstalled Windows
Basically the Fn Button, Left, Right, Up, Down buttons are all working fine. I can adjust the volume of the notebook, but I can't however adjust the brightness of the screen. There is no brightness setting in my notebook whatsoever! Am I missing the brightness driver? what is the name of the brightness driver? Or is it something else. Taking into account that I have decrease/increase brightness symbols on the left/right buttons respectively.
I own an Ideapad Z-500 notebook running Win 8.1.After updating Intel graphic adapter from Windows Update the screen brightness adjust key (F11 and F12) stops working and I cannot adjust my scrren brightness.I have to uninstall it and disable Windows update to keep using my laptop.
I am having an issue with my Acer Aspire V5-431P-4653 running Windows 8.1, namely, I cannot adjust the screen brightness at all. It seems to arbitrarily select a brightness level upon start up and from that point I cannot change it via the Fn and directional keys or through the control panel power settings. I have owned the laptop for a year and a half and this problem began roughly a week ago.
Of note, when I attempt to use the Fn and directional keys the brightness icon that pops up stays at the frozen brightness level - it does not move at all. In contrast, when I open the power settings and attempte to change the brightness from there, the brightness slider will move wherever I drag it, but the screen's brightness itself does not change. At startup the screen's brightness may be at full, minimum or somewhere in between - but regardless it will not adjust.
I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.
I recently got an acer aspire e15 for xmas and I've started to have problems with it like when i turn it on and adjust the screen or simply pick it up to move it the screen will turn off like a standby but take ages coming back on and sometimes it will just simple restart the laptop....
I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.
Today, I tried connecting an external display to my HP ENVY TouchSmart 15 laptop, via a USB hub, only to discover that using the touch screen points at the corresponding part of the external display rather than the inbuilt one (the displays are being extended). Can this be changed?
I'm using the same 64-bit Windows 8 installation and drivers that the computer came with.
