• Cannot adjust the brightness after display driver update on Satellite L855-118

  Hello.

  I just bought a SATELLITE L855-118, with ATI graphics card today, it was between this and another of them, but I know that you have problems updating graphics drivers on a portable Sony.

  I did a restore point.

  So I uninstalled the ATI catalyst graphics card and then did a sweeper driver and rebooted and then installed catalyst 12.6, installed fine, but my screen went to the maximum brightness and I can't adjust, BRIGHTNESS osd is displayed but the brightness of the screen does not change.

  So I used my restore point.

  This time I crushed the catalyst 8.9 with 12.6 stock, still cannot adjust the brightness.

  Someone knows how to solve this problem.

  My spec full in the link below.

  You mean that you can not use the Fn or Fn + F6, F7 button combination?
  Do other combination works properly?

  I get the first screen where you have the choice to configure windows or press 'r' for recovery console.

  After I press enter for the installer, do not me the usual on-screen next where it is said that if the following XP installation is damaged, you can repair it.  Instead, it leads me to a screen where it shows my partitions and asked that one I want to install windows on.  If I choose "C:" he then told me that there is already a system opperating on the partition...

• Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

  Hello

  I recently rebooted my computer; (Packard Bell) and now cannot run games or screen savers because it does not start. I think my problem has something to do with a Direct3D card? When I run screensavers, I get this message:

  Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

  I have the impression that sound when I run the 3D games, such as minecraft or GMOD.

  I run on Windows Vista Edition Home Premium and does not do anything but re - install my computer because it wouldn't start.

  It is not as if the graphics card is not there, so I'm really confused!

  Please help me, like playing games is my favorite thing. ;)

  I also ran minecraft to double check and I got this error code:

  Bad video card drivers!

  -----------------------

  Minecraft could not start because it did not find an accelerated OpenGL mode.

  Generally, this can be corrected by updating the video card drivers.

• Satellite L500 - cannot adjust the brightness of the screen

  I have a L500 - came out with Windows 7. I can't also adjust the brightness - the external monitor is fine. 17 other laptops in the same school are fine - just this one.
  The FN key doesn't seem to work - the laptop screen is so dark, that it is not readable.

  I didn't know all the answers that respond to that?

  Hi redmg,

  The FN keys are controlled by value added and Flash Cards Support utility package. So if you can use t FN keys correctly reinstall these two tools of Toshiba. You can download on the official page of Toshiba:
  http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

  But remove older versions before installing the new versions.

  After that all FN keys should work properly again.

• Cannot adjust the brightness of the screen and the sleep will not work Satellite P750/P755

  On my P750/P755 Satellite I am unable to adjust the brightness of the screen.
  I can move the scale but nothing is happening on the screen.

  Also in the last two days not possible in mode "sleep" as it did before, even though I haven't changed anything.

  What did you do with your computer laptop last days?
  On this virtual path, it is not possible to say what the problem is here.
  You have installed updates? I mean all this can happen without reason?

  Have you tried to roll back the OS to an earlier time to check the functionality?
  And Yes, do you use the original pre-installed OS that you got with your laptop?

• 100 s-11IBY computer laptop (ideapad) - cannot adjust the brightness of the screen - windows 10

  Hello my f11 and f12 keys is no longer adjust my brightness. The gauge up and down, but does not change the brightness. I tried to update the graphics card in Device Manager, but he says that it is up-to-date. Same thing with 'Generic PNP Monitor' said that it is up-to-date. I wiped the computer clean and 'reset' and reinstalled windows and it still does not allow me to adjust the brightness of the screen

  I'm not incredibly intuitive with computers, but I followed the instructions as much as I could find during my research online with nothing doesn't.

  Initially, the problem occurred when I used out of ignorance a program to install the drivers it says have been exceeded. After that, my audio stop working and my keyboard stop working entirely. After resetting the computer and windows resettled, the only question that remains is the brightness of the screen not being able to be adjusted.

  This drives me crazy, can anyone help me? I would be very happy! and please let me know if you need more information regarding my laptop. Thank you!!

  I thought about it. My drivers intel had to be installed since I reinstalled windows. I used the utility of intel and updated driver to update the graphics card update

• Cannot adjust the brightness of the screen with the keys Fn on new L540 (8.1 x 64)

  Hello everyone. I just bought a new L540 with 8.1 of Windows x 64 on it and have met a problem that I see is apparently common. While my other Fn keys work as expected, I can't adjust the brightness of the screen with them. By pressing the buttons just does nothing and the laptop is in running at full brightness at any time, even on the battery. I installed the latest driver for managing power and from what I can tell, there is no version of the management software supply for something newer than Windows 7. I also installed the latest driver for the shortcut key (in fact, I installed all the latest drivers for this machine.) I read in another thread that this may be caused by the latest driver from Intel's HD graphics card but in fact, I can not install even this driver (said my system is not supported) so I always use the latest version of the driver Lenovo provided.

  Can someone please help with this? I want to be able to quickly adjust the brightness of the screen when it is on battery, but I can't do it right now. Thank you!

  I have the same problem with my L540. It started with the BIOS update to version 1.65. Because I have not found a solution, I went back to BIOS version 1.64, where all the brightness options are there and are working properly.

  You can download older versions. When on the page with the new drivers (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS037285) go to BIOS driver 1.65, then choose "learn more." At the end of the next page, you will see all the old versions.

  You can install the version 1.64, you should choose the Option "Secure RollBack prévention" in the BIOS: restart the computer. When you see the option "to interrupt normal startup, press enter", press ENTER. Once more, press ENTER. Press F1 to enter BIOS Setup utility. Click on 'Security'-> then "update Bios UEFI Option'-> then"set RollBack prevention. " Change this option to "disabled". Press F10 to save the configuration changes and exit.

  After you restart Windows, you can install BIOS 1.64.

  Another possibility is to wait for the next version of BIOS...

  I can't adjust the brightness of my screen using the power manager. Update to the latest version of the ThinkVantage Communications utility did not help the cause. I can't make the screen more bright or dimmer, and it's driving me crazy. Any advice would be great!
