• 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.

  Windows 8.
  Now 2.3 times while I was reading a book, c#, abrupt change of brightness of the screen that's happened.
  Usually I keep the low brightness, by 3 ups above the lowest brightness level.

  PS: I recently installed a game that the processor runs all the time on 98%, all playing me, could he be burning CPU... This is the reason for this sudden change in brightness, is my laptop dying lol, Please help!
  Thank you!

  Hi Kaloyan,

  This could happen because of the active adapter brightness or the obsolete drivers display

  I suggest to update the display via the Device Manager drivers and check.

  -Press X and Windows , and then select Device Manager.

  -Browse graphics cards, do a right-click on the driver and click on Update driver software.

  -Restart the computer and check if the problem persists.

  If the problem persists, then disable the brightness map settings in the Power Options and check.

  -Press the Windows key and D to get to the desktop and then click on the power management on the system tray icon, then choose the more power Options.

  -Click on the link change plan settings on the selected plan and then click on the link change advanced power settings .

  -Browse down to display, enable adaptive brightnessand change the settings of one off.

  Check if the problem persists after trying these steps.

  If you have any questions, please let us know.

• Manually change the brightness on the display screen.

  How to change the brightness when the blue Fn key don't decrease the screen brightness but don't don't increase the brightness of the screen.  How to manually change the brightness of the screen without the keyboard shortcut keys (they do not work)?

  Depends on the brand and model of your laptop. Did you install drivers from the manufacturer, or done it with XP (assuming that you do not have XP) pre-installed. For example, on my Gateway laptop, Fn + F8 lights up the screen, and then if I press it again, it fades. Or with keys Fn + I can brighten it gradually, and Fn + darkens it gradually.

  You can figure out or dim the monitor in the video control panel (again, this depends on the manufacturer of card or portable video). Right-click on your desktop and choose Properties. Then go to settings, advanced and then (probably) the video card/chipset that is installed. Somewhere there may be settings to adjust the brightness or gamma of the display. Without knowing your material, I can't say for sure, but it would be the starting point.

• 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.

• Satellite L450D - cannot change the brightness of the screen more

  I was wondering if someone could help me. All of a sudden, I noticed that I can't change the brightness on my laptop what so ever. I don't know how long it has been like that but its pretty boring.

  I am currently running Windows 7 Home premium on the laptop just for information. I tried to change in power management and try to change the management of the real power, and pressing fn + f6/f7

  Any help would be appreciated with gratitude

  Hi telford_boi,

  Can you notice other work of Fn keys or just the screen brightness doesn't work more?

  In your case I would try reinstalling the package of value added. It controls the FN keys you want to say and all these special functions. You can download it here:
  http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

  Before installing the latest version, delete the old first, please.

  I tried all the drivers of hp, but none of them solved the problem, but after searching the Web, I happen to find a solution to the problem brightness screen... now everything works the way that is supposed to.

  It was just to install a new version of the 'Mobile Intel (r) 4 Series Express Chipset Family"from Intel, the driver provided by HP seems to have a problem.

  Thanks anyway.

• 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.
