• MY DELL INSPIRON 15 3521 BRIGHTNESS CONTROL QUESTION

  When I bought my DELL 3521 a few weeks ago, that came with OS Ubuntu, I remember the brightness of the screen is adjustable using the Fn keys (F4 / F5).

  Since I installed Win7 a few days back the brightness of the screen remain very dull (maybe the lowest setting), that doesn't bother me for my day to day work. But for my photo and graphic work, this intensity is far from satisfactory.

  I have checked the internet on it and seen a lot of you also share the same experience. I did almost all of the advice given in it and since there was no improvement, I downloaded all the drivers on the official DELL site for Win7 and install.  Then something happened, it's now, I could see the brightness and the volume of the control on-screen icons or symbols.  Incindentally control of its (speaker) works very well (Fn/F10/F11/F12), while the screen brightness indication appears without any response to the keys (in fact, it indicates the maximum brightness in the scale, and when I try to reduce the scale reduced by point/scale and rest and not move any further).  However, there is no change in the brightness of the screen, which as I have already said, is low.

  I have not yet decided to contact the dealer on this issue which might be a small question perhaps, that I am lying to reconcile with yet.

  I don't know how to solve this problem. Is this a technical problem or a manufacturing defect? Could someone help me please. Must be very grateful.

• Can not change the brightness control does not work

  Hello

  Is IM having sony vaio e15117 possible to control the brightness of the computer

  When the brightness control menu does not work please give me a solution

  Hello Shaik,

  Thanks for posting your question on the Microsoft community.

  Thank you for details on the issue.

  This problem may occur because of corrupted display drivers or incorrect display or power settings.

  I suggest you to perform troubleshooting of power utility and check.
  Reference:
  Open the troubleshooter of power
  http://Windows.Microsoft.com/en-us/Windows7/open-the-power-Troubleshooter

  Troubleshooting of power check things as settings timeout of your computer, which determines how long the computer waits before turning off the display or enter the mode 'sleep'. These settings can help you save energy and extend the life of the battery in your computer.

  Please also to update the website of the manufacturer of the computer display drivers and check.

• Computer laptop HP G72-130ED - the screen brightness control never worked again

  Hi people,

  I've had this laptop again (in 2010) and control screen brightness function keys never worked.

  All other functions working keys, it's just the f2 and f3 (light downwards and upwards) are not.

  All updates (from the site of HP Netherlands) support have been installed.

  In addition there is no brightness control of in control panel windows or which would allow control over the brightness using the mouse.

  It would be great to have control of the brightness of the screen because the screen is really bright and it is unpleasant to use in any other circumstance during the day!

  Grateful for your help, Zion.

  Hi people,

  Just found the solution myself:

• Portege M200 tablet - screen brightness controls F6/F7 does not

  We bought one of these machines, but had to install our own special Tablet build PC in order to comply with the specifications of safety of our society. Now the F6 and F7 brightness controls do not work.

  Hello Laurence

  From my experience, you need the Hotkey Utility for display devices. The new version is v2.6.0.000. You can find this tool on the Toshiba site.
  Please take a look at this site:

• HP 14 laptop: brightness control problems

  Hello

  My mother has recently bought a new HP 14 laptop and when the AC is plugged in, the display BRIGHTNESS varies from no visible state. Brightness controls are also reversed, for example when I press the brightness control, it will be brighter.

  I thought it could have been a graphics driver issue but I have updated graphics for the latest versions and still no change. graphic design is a "Intel HD 4000'.

  All the solutions to this problem would be great,

  Thank you

  @lm13181,

  Hello and thanks for the display on the HP support forums.  With Windows 10 some of the performance parameters are a bit off.  The first thing I would try is running an update of the system BIOS.  Or BIOS Reset would be my first choice.

  Here is a link to help you with this.

• Live webcam updater screwed to the top of my Acer W4 (brightness controls and screen Metro broke)

  UGG knew the deivce is working good

  I did a live update for a new bios it installed and work, after the reboot, my screen metor is slow, he hasmore icon than he had done previously and now my brightness control has stopped working on the screen. I can't turn down the brightness at all in the control parameter or power controls.

  How to take the subway at only 3 rows of icons and how do Iget my brightness control works again? It's virtually unusable tablet, screen is bright andmetro screen is horrible slow. Already done a reboot, live update shows no new updates.

  Need help on this a little.

  Nevermind, I saw in the device manager that the firmaware somehow wantedanother restart to complete the update of the firmware. Very strange, because it seems to complete the first time and the live update did not show anything in the waiting.

• Satellite A660 - 11 M: Nvidia GT330M (258.96) driver brightness control

  Hello

  I bought a Toshiba laptop (model A660 - 11M) with a Nvidia GT330M and I tried to update the driver with the latest version of verde (258.96).
  The installation is completed without problems, but when I restart the laptop control over brightness (via fn + f6 or f7 and the cursor in the menu windows dedicated Control Panel) disappeared.

  Or rather, if I try to change the level of brightness in this two way, the cursor and the fn keys work togheter (if I push the fn + f6 buttons of the windows cursor returns but the brightness is not affected) but without effects on the brightness of the screen.
  The only way that works is to adjust the brightness through Nvidia Control Panel.

  Obviously with the pre-installed driver (189.16), everything works perfectly. I also tried to uninstall, clear with DriverCleaner and reinstall the new driver, but with no better result...

  I hope someone could help me...

  This question seems to be already discussed in this thread:
  http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=55182

  It seems that the original driver from nVidia is not fully compatible with the FN keys, which controls the brightness
  However, the Toshiba driver works as it should so it s recommended to stay with the Toshiba drivers, given that these drivers are prétestées and compatible with other applications.

  In addition, pilots don t support nVidia GPU overheating protection and the use of these drivers is only at own risk

• Satellite Pro R50 - brightness control F3 does not work

  Hello

  I have a R50 Pro Satellite - bought just 1 month ago.

  Suddenly the order of function F3 to control light intensity has stopped working.

  The brightness can down with F2 function but F3 does not work

  F3 in the software and the operating system back to research, but do not work by pulling the brightness setting.

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

  I downloaded the latest driver for the feature key and installed, so it isn't that.

  Anyone got any help they can give?

  See you soon
  Craig

  As a temporary solution, you can change the brightness in the power settings.
  I really don't understand what the problem may be, but try to reinstall the utility system then Toshiba and Toshiba driver to feature key.
