Fn Brightness Control lost, Toshiba Laptop

Q: Fn Brightness Control lost, Toshiba Laptop

I had to format and re-install Windows XP on a Satellite A105-S4201 Laptop. I installed XP, and updated to SP3. The brightness control no longer works using Fn+F6/F7 (or any other way for that matter). It was working before the format.
I tried a couple of different Common Modules installs. This one: tc00324000b (version 6.07.03) won't even install. Gave me error message, "TVALG Driver installation has failed". And this one: SPA210 TCommon Modules-XP (version 1.00.06) installed, and had me restart, but when I tried to install the hotkey utilities afterward, it said "TOSHIBA Common Module not found! This setup will terminate." Also, I have the latest BIOS version installed (v 6.0)
Any ideas?

Preferred Solution: Fn Brightness Control lost, Toshiba Laptop

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I suspect you need to go to the Toshiba site and see if there is a document telling you what drivers are needed AND the sequence to install them.

I bought this laptop used with Vista on it and the LCD brightness control wont work. The Brihtness is set at default level which is tolerable but non the less i cannot adjust it brighter or less. I reinstalled Vista and installed XP media center edition and still cannot get the brightness to adjust. I have installed all of the toshiba drivers for this notebook including the recent ACPI bios and hotkey application. I am currently on XP MCE.
If anyone has any ideas to what could be wrong i would glady appreciate it. I have been at this for a few days now and no answers not even from the Toshiba site.

Thanks

A:Brightness Control Hotkey No Working On Toshiba P105

I assume this is the "push the Fn button and another key" thingie? If so, check to ensure that the Fn key works by pressing it and one of the other functions to see if that works.

Then test the key that you use to adjust brightness - without using the Fn key. Does that key also perform it's designated function?

This'll let you determine if it's an error with the keyboard.

Hi guys, i am facing this weird problem today. It happened suddenly without me doing anything like update or messing with drivers. It happened all by itself.
My laptop brightness is locked. I am used to hotkeys (shortcut) to change brightness, When i press them now.. i see a bar which won't go up or down, it's locked and brightness too. I went to "Power Options" page via control panel, and i altered the brightness slider but it didn't help.
Any suggestions??

Things i tried..
-Restarted Pc..... nothing
tried to fix using this post.... Brightness won't adjust after Windows 8.1 Update
-I tried to update Intel HD Graphics 4000 driver but it says it's up to date.

A:laptop brightness control problem

Try booting is Safe Mode. Then go into Device Manager. Delete the video drivers. Reboot normally.

Windows will reinstall the driver that was already in use before you deleted it. But I have seen this "support trick" work with many different hardware components.

It is very low risk so even if it doesn't work it was worth a shot.

I have an Acer Aspire 8935G with W7 HP 64 on an SSD and Vista HP 64 on an HDD. The Fn keys controlling the display brightness control work on the Vista boot but not on the W7 boot. All the other Fn keys function as they should on the W7 boot. The Aspire has an OEM ATI Radeon HD4670 graphics card. I've tried all 3 available driver versions for the card & OS from AMD but these two Fn keys won't work. Any ideas what's going on here? Do the W7 drivers override or deactivate the Fn brightness control keys?

Hi

You could not lost the product key because the recovery disk is already activated.
So you don?t need any keys to install the OS using the recovery disk.

But if you lost the recovery disk then you could order this from here:

But it?s not for free? you have to pay a small fee.

A:toshiba laptop lost recovery disk what to do

if you buy a new windows and install it, it will wipe the whole hd and install your windows on it. This will get rid all the files on the hd.. This will remove the virus and whatever you have on the laptop, so all your files and such. When you install the new windows, make sure you choose format to format the HD to ensure the HD got wiped clean. Then proceed to windows installtion. AFter it's done, go to toshiba's website and download the needed driver for your system.

then how can I reduce the brightness of my laptop.
please help on this

A:toshiba brightness issue

To get the function keys working you can go to Desktop Assist (Toshiba) > Tools & Utilities > System Settings > Keyboard > Special function mode.
Even if it looks right do an Apply > OK that will probably start the service up again. Or you can reboot.

However you can simply use FN+F to access the functions anyway.

Other ways to the Brightness are Charms Menu > Settings > Brightness (Windows 8.1).
Or Control Panel > Display > Adjust Brightness.

You can go to Toshiba support and download the Function Key utility, and System Settings utility from them.

Hi, I heard that the 4k display on P50 and P70 both use PWM for brightness. Is there any information about FHD on P50? Thanks










Solved!
Go to Solution.

A:Does P50 FHD use PWM to control brightness?

To make it clear, all displays use some kind of PWM to control brightness, it is almost impossible to do it without using it (HP DreamColor might be the exception, still not sure), especially in laptops. The big difference is how the PWM is implemented, what frequency and modulation it uses. So the "PWM-free" so called displays are rather an "annoying-free PWM implementation" displays. It is not a rocket science, just the level of cutting costs applied, as usually these days. How comes that a cheaper model can get better quality display than an expensive one ? Because no one cares. It is just "component" having size and pixel resolution. Unfortunately you have to wait for deep detailed reviews like notebookcheck site do because the price tag does not guarantee any quality anymore Even worse scenario, if there are multiple vendors of the "same" display for particular model (T440 LG vs AUO etc.) you are completely out of luck. Frustrating, eh ?

Usually on laptops/notebooks, there's a Fn key combo nation that controls the brightness. On my Samsung RV511, it's the Fn key + up/down arrow that controls my screen brightness. Check your notebooks manual for your controls. Otherwise go to control panel, hardware/sound, display and then look in the left pane for adjust brightness....click on that, then look at the bottom for the slider and slide accordingly.

Try going to Display Properties in the Control Panel and click on the advanced settings buttons. Most manufacturer's drivers have color and brightness controls for the card that stay put when changed. If it's just the players that are too dark, look for an "overlay" adjustment. If you don't see those settings, look for an updated driver for your graphics card.

On my IBM Thinkpad T43, the brightness controls no longer work. Pressing Fn+Home/End is supposed to lower/raise the setting, and it used to, but no longer does. It's also supposed to lower or raise the brightness depending on what power it is running on, but no longer does that, either.

I tried restoring to my original XP image, where it worked fine, but it still does nothing. Given that it used to work anywhere (BIOS, etc) I'm beginning to think it has nothing to do with XP's setup, but I can't seem to find a BIOS setting that makes a difference, either.

Any ideas?

Recently bought above laptop and downgraded to win7. The brightness slider has is not there in the power settings, the fn keys don't work. I've tried the drivers from the Toshiba website for the c50 distro. I've tried uninstalling the monitor.

I've asked over at the tosh forum but its dead over there. My eyes are bleeding looking at at, wearing sun glasses i still can't look for over 5 minutes

Can anyone offer a solution?

A:Can't adjust brightness win7 toshiba c50-a-1jm downgraded from win8

Hi Welcome to Seven Forums .. You could try using another Model of the Notebook for your Drivers .. The big problem you face is that you Downgraded to Windows 32 Bit .. Unless you Install the 64 Os it is going to be very difficult to get all your Functions working .. Plus you are not making the best use of your Ram ..

I can't change brightness on Toshiba Tecra S11 with Win7 using FN keys (sound disable and others work fine) when logged as normal user.
Hotkeys console appears and when pressing F6 or F7, brightness is always set to level 1 (no matter how bright monitor really is) and can't be changed.
I can change it via Power Options or logged on as an administrator.

A:Can't change brightness on Toshiba Tecra S11 with Win7 using FN keys

Hi

Maybe you didn?t install VAP (value added package) for all user accounts.
Please reinstall VAP using your user account.

You can also check if the user account supports Admin right.
You can run the single applications (exe) as admin.
For that you have to click right on exe file (value added package) and should chose +Run as administrator.+

Check this!

If you have a Mac with Windows 8.1 you may notice that the text is fuzzy after installing the Boot Camp Support Software 5.0.5033... also th brightness controls do not work on the keyboard.

To fix this issue I did the following:

1) Go into the Device Manager and disable the Generic PnP Monitor under the Monitors item.
2) Go to AMD and download the 13.11 Beta AMD Catalyst? Notebook Display Driver. Install.

After a reboot the display looked much better and the brightness works too! Hope this helps people out there trying to get 8.1 configured on their mac laptops. Enjoy!

Most monitors control this using the old method of buttons on the side or lower frame of device.

Hello, can somebody point me in the right direction to solve the following problem. I have just purchased an Acer Aspire F5-573-52MU Laptop and a week after purchase (Sept 2016) my Fn Hotkey stopped working when I try to increase or decrease the brightness (Fn + Right or Left Arrow), but it still works when I adjust the Volume (Fn + Up or Down Arrow). I have also performed a complete factory reset (As suggested by ACER Support), but to no avail? The screen needless to say is very bright and with no control over the brightness leads to a faster discharge of the battery. Has anybody encountered a similar problem on this model, any suggestions to rectify this would be gratefully received?











Solved!

A:The FN brightness control keys on my Aspire F5-573...

It would seem MS Win10 auto update "might possibly have updated the driver" creating a loss of the hotkey functionality. This would also explain why my factory reset/install failed to correct the problem? Replaced the monitor driver manually in device manager by selecting the generic PnP Monitor version. PROBLEM SOLVED, Yah!  Although I feel this problem may well happen again on the next update (I hope not)! Anyway this cured my problem...

Hi there,

I've got a Satellite Pro R50 - bought just 1 month ago.

Suddenly the Function F3 command to control the brightness has stopped working.

The Brightness can go down with Function F2 but F3 doesn't work

F3 Works in software and the Windows OS to pull up search, but not pulling up the control for brightness.

As such I'm stuck with my brightness down as low as it goes.

I've downloaded the latest Function key driver and installed, so it's not that.

Anyone got any help they can give?

Cheers
Craig

As temporary solution you can change brightness level in power settings.

Hi,
I have a Sony VAIO CW Core i3 laptop which is running Windows 7 Professional Service Pack 1 64-bit. I cannot change the brightness anymore (probably since the SP1 update).
I get this: http://puu.sh/1nWX It maxes out at one bar. Furthermore, the brightness control is now gone from Windows Mobility Center: http://puu.sh/1nYJ

My video card is nVidia GeForce 310M. I've already tried methods mentioned in other forums as well as Sony Support, such as installing and reinstalling Sony Shared Library and Sony Notebook Utilities, as well as uninstalling all nVidia drivers and reinstalling them.

I've tried installing the newest nVidia driver from the nVidia website, but that failed and told me that I don't have compatible hardware (which is crap because I chose the right model..)

What else can I do? Is this because of Service Pack 1? Is there anything else I could try before trying to roll back the service pack?

Thanks.

    I'm using Win7 64bit in Inspiron 3542.
   After i resume windows from hibernate, brightness control is not happening using quick keys. Every time i need to go to control panel & change manually. Other quick key functions are working except the brightness control.  The brightness bar stuck like below.

  Even killed quickset process & opened again, nothing useful in it. But when i reboot the system it starts working, and problem starts again when i hibernate.

A:brightness control not working after hibernate

I take it that when you notice this, restarting the notebook corrects the problem every time? I am not suggesting this as a solution(sometimes i would rather see the dentist than have to restart one of my PCs) but I want to make sure that this isn't a hardware issue. 
When you notice the problem with the brightness keys try holding down FN when pressing them and see if there is a change. 
As another test go into Windows and change the power plan and change it to "high performance" before hibernating the notebook. Before resuming plug in the AC adapter and see if you are now able to adjust the brightness, if you are able to then this becomes less of a problem with the function key behavior and an issue with power management.

By accepting the solution when the issue is resolved, others will be able to find the steps that work also.   To help computers start faster, on some models the HP splash screen is not displayed during the start up process. In this case,you can try these steps to see if it is possible for you to enable the HP logo screen:Restart the computer.Press F10 repeatedly to enter the system BIOS screen.Select the Boot section using the right arrow key.Select Boot-time Diagnostic Screen using the up and down arrow keys.Press Enter to select boot-time diagnostic.Select Disabled to show the logo screen.Press Enter.Press F10, and then press Enter to save the changes and exit the system BIOSThis should enable the splash screen if it is available to be enabled.  If this reply helped, please use the Accept as Solution button.

Since updating my HP Pavillion 64 bit to Windows 8.1, I have been unable to use an HDMI cable or reduce the computer brightness. I figured it would be a simple fix: restore to before the update, and wait for the bugs to be worked out. However, every time I attempt to access the control panel to perform a system restore, the entire OS freezes. Can someone help me resolve this?

Update: I tried to power on my computer just now to no avail. Stayed on the HP loading screen for 30 min.

A:Cannot Reduce Brightness Use HDMI or Control Panel w/8.1

Sounds like a Hard Drive issue, first things first, try checking your whole hard drive. Download Hiren's Boot CD from my link below, burn it and boot to it. Go into Dos Programs and you'll see Hard Drive Tools, pick the tool for your brand hard drive and run a full scan on the surface. You can also try GWscan, which can do both Seagate and WD drives, look for "read element failure" because that error will cause that 30 minute non-boot in some cases.

Sometimes a bad or corrupted spot on the HD will cause all kinds of other apparently unrelated and insane problems, so check the disk before doing anything else.

If you have an SSD drive in there, then do not do any of this, you will have to use the tool for the drive made by whoever made it, or simply so a CHKDSK, you can do that from Hiren's using Mini XP, it's better to do it from there rather than let Windows 8 do it, especially in the state it is in now.

I am not able to make the indicator disappear.In the same time some operations slow down (e.g. I have problems writing an email - the letters appear in the screen a few seconds (or dozens of seconds) after pressing the keys. The start button (both in the screen and the start key in the keyboard) do not work, the touch control doesnot work properly, the hot-keys (like alt-tab) do not work.... I though maybe some of the new actualizations do not cooperate well with the drivers - I tried to uninstall recent actualizations, but without any success. Can you please tell me where is the problem and how to fix?

A:Need to turn off / remove HP proprietary screen brightness control

Hi there .. I have seen this feature before think it was on an Asus Laptop ... I have had a look on the HP Website and can not see any Software that relates to this issue .. It could be well hidden though maybe in the Tools .. I am pretty sure the Function Keys do not have control over that..Could there be a Setting in the BIOS to turn it off ? I suppose if it was Software related one way to get shot of it would be a Clean Install with out all the Bloatware ..

Hello There are countless threads with people who can't change brightness on Windows Easily solved switch to the generic Windows graphics driver However to me this solution removes the Sleep option in Power menu Only Hibernate is left but I don't want to use it I just bought a W10 control, Brightness pick Sleep OR Graphics driver: one small SSD for the OS and I want to save the write cycles So as the situation stands I can either choose to have the Sleep option with Intel Graphics driver W10 Graphics driver: Sleep OR Brightness control, pick one or have the brightness control with the Windows graphics W10 Graphics driver: Sleep OR Brightness control, pick one driver I chose the former because I use sleep a few times a day W10 Graphics driver: Sleep OR Brightness control, pick one but don't change brightness very often But I want both I am just checking is there any option to have both sleep power setting AND working brightness control in Windows Is Microsoft or Intel working on fixing the problem - I use two graphics drivers at once - NVidia and Intel Can't have just NVidia that removes both brightness and sleep - Yes I have the latest Intel driver - Yes I have disabled adaptive brightness - No I can't adjust brightness manually if I try that the screen is totally dimmed and I have to switch the drivers to fix it - I have Lenovo Z Windows with the Anniversary package - didn't help - I made a clean install of W after my old W install got stuck in update-remove update loop

Hello and welcome to the forums Buck.

I don't think disabling services is a good way to get rid of malware and adware if that's what you mean? If I was you I would do a system restore to before he disabled the services and see if that works.

I purchased Dell Inspiron 5558 (with Windows 10) just two months ago (Nov 2015). Everything was working fine. However, recently I started to notice an annoying thing with the function keys F11 and F12 for reducing and increasing the brightness respectively. 

Without using the Fn key (next to Windows key), if I hit F11 it was reducing the brightness and F12 was increasing the brightness earlier - as expected. Now, sometimes, the laptop monitor goes to sleep mode the moment I hit F11 or F12. I have to press the power button again to wake it up. This behavior is very off and on and not consistent.

Did any settings get changed? How to fix this? Please help.

FYI - I have not changed the BIOS settings from default which could be multimedia. I can say this because other multimedia keys in the same row behave normally (even when this strange behavior is noticed in F11 and F12).

Thanks,
Shashi

A:Function keys for Brightness control (F11, F12) do not work as expected

Hello Shashi,
The settings for those FN keys are handled by the Dell Quickset Utility, and later the Dell Command Configuration application, so any changes you would want to make would be done in that application.  
I would suggest going into that application and seeing if you can change the settings.   Putting a system to sleep is one of the functions available so perhaps the configuration has changed.   If you want additional help please click on my Dell Todd username and send me a private message with the Dell Service Tag of the system and I'll see if I can help.   Please keep all discussions and troubleshooting here in this thread so that others, with the same questions or problems, can see what is done to resolve.
Todd

Many people having problems with the brightness control (doesnt work) when you resume your notebook from sleep/hibernate. I noticed that the problem only occurs if you set the action (sleep/hibernate) for when you closing the lid. But if you set the sleep/hibernate action for the powerbutton, the brightness works fine on resume.I have search many sites but no one has a fix yet. Does MS knows about this brightness problem for W7 ?

Good afternoon everyone, The monitor I presently use in an AsusTek, VH198. Although, I have lowered the brightness level to 0, and adjusted the contrast some, the screen still seems to be too bright...especially at night-time.I've briefly looked at a few of the free monitor brightness/dimming control software applications available, but am unsure if they will actually enable me to lower the screen brightness more than what it presently is.My questions:1. Are any of these programs really effective?2. Is there any risk associated with them?3. Any recommendations as to a good one to try?Thank you for your time and any insight!

I can't seem to find the brightness control slider in the usual places like power management, Display etc . My current keyboard does not have the Function keys with brightness buttons like the original Sony KB. Does this mean I need to connect up the old keyboard to perform this ?

Someone used my notebook and the display got bigger, and blurrier. I fixed the blurriness, and I can't really change the resolution except for 800x600 and 1024x768. I thought I had more options than that. Also, when I go to Power options under control panel to changes plan settings, the slider where I could change display brightness is nowhere to be found. So when I unplug the power cord, the screen no longer dims. halp me guise!

I have HP pavillion DV6703TX laptop and there is a problem with brightness in it. When it resumes from sleep its brightness change control stops working, means it cannot be changed either by F7 and F8 keys or by power management option in vista settings. Also brightness option in windows mobility center is not shown after this happens, every other options like sound, battery state shows on hitting WIN+X. So to change brightness I have to restart windows then it works completely fine and brightness option also shows on mobilty center box. Is there any hotfix for this like there was one for sound problem after sleep in vista. I have upgraded the latest available video driver on driver download support section but the problem persists. please help :-(

Hi guys,

The following set of exes allow you to map custom buttons on laptops to Windows shortcut commands . Currently supported is : to increase and decrease volume/brightness by a single click . Quick brightness change is great for long gaming or development sessions on the pc !

I have been missing that feature badly.

Also sending shortcuts i.e ALT+TAB is supported.

You need your laptop to have the software that can map the button to the exe.

This is donationware so all help is appreciated.

Coming soon also one-button changing the Nvidia color levels, as this is another thing that has been killing me.
Get it here.

Hi,
Occasionally, when resume from hibernation/suspend, display brightness control doesn't work. Means that Fn + F2,F3 doesn't work, change from Windows Power Options doesn't work, change from intel graphic doesn't work.
Anyone know if I have to restart some services to get it working? It's occasional and I can't find anything exact in EventLog.
My system is HP Probook 4230s with Core i5-2410 with intel HD3000. Latest patches on both Win 7 Pro 32-bit and intel driver.
Restart machines solve the problem, re-hibernate or re-suspend machine occasionally solve the problem, but mostly not.

I recently purchased a Dell Latitude 7370 with the QHD panel. I was very surprised to find that the new 7370 line is plagued with the infamous Dynamic Brightness Control "feature" that cannot be disabled, especially when Dell is just now removing DBC from the XPS 15 and XPS 13 QHD models.
Dynamic Brightness Control is a dealbreaker, and I would not have ordered the 7370 had I known it was a supplied feature. Is there any information as to whether or not a patch is in the works to be able to update the display firmware to remove DBC in the near future? Any help or information about how to disable this will be greatly appreciated.
