• Impossible to change the bright screen on Satellite Pro C50-A-143

  I run windows 8.1 and I could not change the brightness of the screen for a while now.

  It happened a few months before, but after a random number of days that it worked again, now it is stuck in about 60% bright max, which is not enough when the sun comes through the window.

  According to the Toshiba Satellite Pro C50-A-143 datasheet this laptop has been preloaded with Win 7 64 bit and Win additional 8.1 own drive was part of the package.
  I assume that you have installed own 8.1 win but have not installed all the drivers Toshiba win 8.1.

  Is this correct?

  Visit the page of the Toshiba UE driver, install all the drivers, tools and utilities (graphic card drivers display tool, driver Toshiba system, etc.)
  Utility function key Toshiba is very important if it is to use the key function (Fn, F1-10)

  Then you should be able to use the function key to decrease and increase the brightness of the display.

• Satellite L50 - B - 12 G - can't change the brightness of the display

  Hi people,

  For some reason that I can't find out, since yesterday I can not change the brightness on my deskop.
  It's a Satelite L50 - B - 12 G with Windows 8.1, 64 bit.

  (F2 and F3) function key does not move the scroll bar, and when I try the same thing on the control panel is like this:
  It is not simply to change the brightness

  At the same time, when I'm with an open office document or on a web page, don's work the cursor as usual... it is slower to move from one cell to another cell in Excel for example.
  The sane is to arrive with the page down key.

  Can anyone help on this? It becomes very annoying.

  Best regards
  Jose

  How did you try to increase or decrease the brightness of the screen?
  Did you press the FN key also?

  Well, as you said the F2 and F3 keys increases or decreases the brightness of the display
  The extra pressure of the FN button depends on the key mode feature which is located in:
  Office Assist-> tools & utilities-> Control Panel-> keyboard

  Permit special mode button allows you to use special features without pressing the FN key.

  That's why I recommend that you check this setting!

• Satellite P855: cannot change the brightness of the screen under Linux

  Hello, guys... and girls :)...

  I bought my PC Toshiba laptop fourth - P855, there windows 7 pre-installed, but I'm a fan of Linux, so I installed Kubuntu 12.04 on it and have the dual boot menu at startup...

  And I have a very annoying problem - I can not change the brightness of the screen somehow, so keep it up... for the brightness function keys do not work, and the slider for brightness change anything...
  It works on windows, so I guess that's not the hardware problem...

  So, can you help me? ... I tried many things, tried different distributions also, but on none of them, I am able to change the brightness. And also - I tried the same distribution on the different laptops, and it works great, even from Live CD, no installation...

  I was able to change the brightness on previous phones I had... so why is this one so well done for Windows? ...

  > It works on windows, so I guess that's not the hardware problem.

  It's okay is not hardware problem, it looks like a bug in the Linux kernel or driver problem.

  Given that Linux is not officially supported on Toshiba laptops, I would recommend checking the support forum for the Linux distribution you use check also system Linux bugs for a possible solution on some linux support pages.

• Portege 3480: How to change the brightness of the display

  I recently acquired a portege 3480 with xp installed.
  I've searched high and low and cannot find a method
  to change the brightness of the display. Anyone anyone? Büeler?

  Hello

  already tried the fn key combination? I don't know how it is with your portege, but it should be like FN - F6 and FN + F7 to change the brightness of the display.
  Unfortunately, there are no XP drivers (or just the audio driver) for the machine to change it manually.
  You should try the FN key combination, there should be a sign that looks like a little 'Sun' with an arrow up/down in front.

• Satellite M30-404: cannot change display brightness and THCI.dll is missing

  Hello!

  1. a few days I did a reinstall of XP. Now, I can not change the brightness of the screen. FN + F6/F7 does not work.

  2. when I start the computer, a message appears > an application cannot start because THCI.dll be found. A new installation of THCI.dll can help. But I don't know what is THCI.dll!

  My English is not perfect, but I hope you know what I'm talking about and can someone help me.

  Thank you very much

  Concerning

  Tobias H.

  Hi Tobias,.

  THCI.dll is the code for the application of the function of Toshiba key that is used on your laptop to control the selection of Fn key. You will need to install the utility Toshiba control of your tools and Utilities CD (or download from the Toshiba Download Page).

  Kind regards

• Cannot change my brightness laptop

  Hi all

  So I recently noticed this problem in my laptop and whenever I try to change the brightness low or high it does nothing and I try to the shortcut key and the laptop brightness settings but still nothing. (btw, my laptpo is HP Pavilion g6 windows 7)

  Thanks for providing this information.

  Remember you have downloaded an AMD/ATI graphics driver for the AMD Web site or anywhere other than your driver HP Page? Sometimes non-HP-OEM graphics drivers may cause problems with brightness.

  It would be helpful to know what version of the graphics driver you have installed currently, for Intel and AMD Radeon chips.

  Latest graphic driver Intel version 8.15.10.2559 - relatively new

  Latest graphic driver for the AMD Radeon in version 8.882.2.0

  If your versions are less that the version numbers shown above, go ahead and download the latest appropriate version.

  Also, I'm not sure that it is a problem of shortcut keys, but I would like to just exclude it. Download and install the last pilot of access keys, software framework HPand HP Power Manager utility.

• I can't change the brightness Displal in my Probook430

  Hello.

  I recently bought a HP Probook430 and installed Windows 7 Ultimate 32 bit and I don't seem to be able to change the brightness of the screen, using the fn + f9/f10 (although volume settings are changed in the same method smoothly).

  Although the parameters of brightness do not seem to change, this bar will appear when you press fn + f9/f10.

  

  What should I do in order to make the brightness display editable settings?

  Thank you!

  Hello:

  Have you installed the graphics driver applicable?

• How to change the brightness of the screen on Satellite A200 on Vista

  I have a problem with the brightness on my Satellite A200 - 14 d in vista, the default settings have very high brightness and when I change the brightness after a reboot there are default settings... (VGA is GeForce 7300 go)

  As far as I know there is nothing strange. The same thing was happening to me. If you want to have the brightness of the display on the lever of the lover all the time, it must be changed in power options. Please select your preferred profile (symmetric for example) and set the LCD brightness to the lower level.

  It works for me.

• X 1 yoga - cannot change the brightness

  I just got my thinkpad yoga X 1 by post a few days ago and he is stuck with a maximum brightness. I tried to change the brightness by using the shortcut keys and controls for brightness in the bar of tasks and settings. The brightness meter will change the percentages, but the brightness of the screen does not change.

  I did a factory reset, as well as uninstalled and reinstalled the drivers to display/video and moniter. I did a back roll of these drivers to the generic version as well.

  I called tech support and they said it is probably a hardware problem, and I have to send it in for repair, which is frustrating for a new laptop. I could rather Lenovo to send me a new replacement?

  In response to the customer reports that the brightness of the screen can be controlled via a key entry on X 1 Yoga ThinkPad, Lenovo has released a fix. The patch is a registry change to restore this function.

  The patch can be downloaded here: http://support.lenovo.com/us/en/downloads/ds118463

  A permanent fix will be delivered with the Intel driver in a future release.

  Thank you
