• Impossible to change the brightness in XPS 15 (L521X)

  Hello

  Recently, I noticed that I'm unable to change the brightness with fn + keys, up/down from the display settings, or windows Mobility Center.

  The changes in value, but the display doesn't is hit to some brightness.i.e no effect if I do 0 or 100.

  I tried to update the latest video driver intel as well nvidia driver from the website of sellers, but nothing helped.

  Although I can change the brightness during the laod of bios, but as soon as windows logo, the GET of brightness affects a certain value and I can't change it later.

  I think that this problem happened after updating windows automatic HD 4000 driver, now, I have disabled the windows update.

  Thank you

  Allan,

  You can find the video drivers for Rah21, which can solve the problem. I recently saw this problem and install the video drivers made the controls work.

• 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.

• Impossible to change the password with Net User

  I don't know if I ask this in the right place, I'm new to the community of answers. My environment is mainly Server 2008 R2, I asked the Admins who are unable to use net user to change their own password to a high command line. I checked their permissions and they have two buttons and change the permissions on the user object.

  Using of "net user [username] * / Domain" they always get access denied, it works if I give them full control. Is there permission miss me except change and reset?

• 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 L30 unknown to me, but as far as I know, on all models of Toshiba laptops you can change the brightness of the display by using the FN + F6 or F7 key combination.

  Satellite L30-13 does not exist, please check the description and please give us an exact description (PSLxxx). On this path, it will be easier to identify the model of laptop.

• 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.
