• Re: Satellite Pro S500 - brightness adjustment does not work correctly

  On my Satellite Pro S500 (preinstalled Windows 7 64-bit) change the brightness by pressing FN - F6 or FN + F7 does not work. The other NF - f... combinations seem to work correctly.

  When I press FN - F6 (or F7) a control box to change the brightness to poster (as expected), but the level is still displayed as "1" independent of the current value (for example changed from Control Panel or with the eco utility) and it is not possible to change it with FN - F6 or F7. I just reinstalled vap and restarted the computer, but nothing has changed.

  Hi asdf.

  I put t know what s wrong exactly but normally the FN keys are associated with value added Package, but you wrote that you already reinstalled

  In my opinion, you should try a system restore to an earlier point. Maybe something messed up the registry, you can start System Restore in Windows Advanced Boot menu.

• Satellite A660 - 11 M - brightness adjustment does not work after hibernate

  Sometimes, I find that you use F6, F7 to control brightness does not work. This only seems to happen after a fresh reboot, but after being out of hibernation.

  I am running Win 7 Home Premium 64-bit and using the latest NVidia driver (obtained from toshiba yesterday Web site): 8.16.11.8988

  A way to solve this problem?

  Hello

  From my own experience, I can say that all the FN buttons work perfectly after hibernation, standby, restart, etc.. No problem at all!

  I put t know what is the problem, but in your case would be to reinstall the package of added value and utility to Support Flash Cards. Two tools to control the FN key functions and can be downloaded from the official page of Toshiba.

  But before you reinstall it, remove older versions first. Then install VAP, restart and finally Flash Cards Support utility.

  As you probably know Toshiba doesn't support Linux and you will be lucky if someone here would be able to offer assistance.
  I recommend to visit some Linux forum and ask there. The Forum of Linux you have better chance of assistance with that.

• Satellite A100-683 with Win 7 - screen brightness adjustment does not work

  Hello

  I have a model of Satellite A100-683 PSAA9E with Win 7

  My problem is that I don't have a brightness in my dashboard-> laptop Center

  I tried to install the drivers from the site Web of Toshiba (additional package, return), but stops the installation always with errors such as: value added package: PVAT Setup error

  I tried to install the drivers for Vista...

  Please help me!
  Sorry for my English mistakes.

  Hello

  The installation may stop due to system problems or the PVAT erroneous version.
  I recommend you to uninstall the installed VAP.
  After the PVAT has been uninstalled, restart the laptop.
  Now, download and install the tool small freeware called CCLeaner.
  It helps to clean the system and deletes files temporal garbage from the HARD drive.
  After the cleaning of the system registry, you must restart the system once more.

  Now, go to the page of the Toshiba UE driver and download the Toshiba value added Package for Win 7. Note! Choose the right! There are differences between the 32-bit and 64-bit version.

  Unzip the package, run the exe from installation or installation file and start the installation.
  Installation should finish properly and after new reboot, you should be able to use the function keys.

  Run Windows Update.  It is good for the installation of device drivers that have not been found during the installation of Windows 7.

  Your Windows passes genuine validation? If your activation session has expired and that windows did not pass the validation, it will not show any visual effect such as background noise, themes etc. It will only show a black screen and at the bottom right of the screen you can see attention.

  Regarding the brightness controls, try to use Recovery Manager to reinstall your original graphic driver - how to use the Recovery Manager to reinstall the drivers and software is detailed in the document at the link below.

  Recovery Manager - Windows 8.

  After reinstalling, restart the laptop.

  As far as the keyboard is concerned, it seems that if the incorrect page layout has been selected - IE if @ is on the 2 key must be set to the United States and so " " "is on the 2 key, it must be set to UK - you can change your keyboard layout, as described on the corresponding link below.

  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.
