  Hello

  In your case, I'd install the Toshiba Power Saver. This Toshiba tool is really great because set you the brightness of the screen for different profiles (full power, normal, etc.) and there you can adjust the brightness of the screen. In addition, you can change the method of cooling, the performance of the processor and to this day.
  Check it!

  You can download the energy on the Toshiba page saver. I also have a Satellite L300 with Windows XP and everything works perfectly.

  Here's the order of installation for Toshiba tools, they control the FN keys, etc. :
  Toshiba Common modules
  TOSHIBA Hotkey Utiliy
  Utility Toshiba Touchpad on / off
  Toshiba Utilities
  TOSHIBA Power Saver
  Toshiba Assist

• Satellite R25 Tablet screen - brightness Horizontal gradient - problems

  Hi all

  I have a strange problem with my screen. When I use two brightness levels lower my screen isn't constantly bright he has degraded landscape. Research on the left side, I have very dark screen, near Middle there is the normal brightness after dark Middle again and in the form of o end/right side is clear.

  This anomaly is smarter than on two lower levels of brightness, when I want to extend my battery life.
  I was replacing my Windows XP, but without any positive results.

  The screen must be replaced, or y at - it another way to fix it?

  I'm afraid that it is material. I can't say with certainty that the display is faulty but if bring you the technician can test it with special diagnostics tools.
  As you can see fresh OS installation didn't help and he can't be software problem. Sorry, but I don't think there is anything you can do alone to fix. If possible continue to use display with acceptable light level.

• On the P750-13D Satellite screen brightness problem

  Hello world

  I have a portable Satellite P750-13D. My problem is; When I press FN + F7, the brightness of the screen decreases.
  However, when I press FN + F6, increases the brightness of the screen. Thus, he works in an opposite way.

  What should I do to solve the problem?

  Thank you.

  Very strange problem.
  Are you using the original pre-installed OS that you got with your laptop?
  Have you noticed this behavior from the first day?

  As a general rule I don t hear big problem. I imagine that you use different powers and for each plan power plans, you can set certain level of brightness. Using FN + F2 keys you can change the profiles of power and brightness level too.

• Satellite U840-10V - screen brightness problem

  Hello
  I own a U840-10V laptop and I have a little problem with my screen brightness from the first day I got it.
  The fn keys work correctly. When I press the button Fn + F2 or F3 I see small panel brightness adjustment, but values 1,2,3,5,6 and 7 (except 4) seem to have the same level of brightness (the 4th is darker).

  (I had problems with my backlit keyboard as well, but when I reset the defaults in the bios it worked perfect...)

  so is that what someone knows how can I fix?

  I reinstalled the PVAT to a newer version which was suitable for my laptop and windows7 - 64 bit, on the toshiba support site, but I haven't worked out.

  so if anyone can help me I would love...

  Thank you...

  > I have a little problem with my screen brightness from the first day I got it.

  It works correctly when you change the brightness level in the plan directly to settings?

• Dell 11 place 5130 pro 32 bit flickering screen brightness

• My screen brightness settings do not stick after that I reboot my computer

  Hello

  When I put my screen brightness for the "connected" by setting the parameter changes on the same level as the 'on battery' setting after I reload. How can I fix it?

  Thank you

  Christi

  Hi Christi,

  Windows can store the brightness level of DC correctly in the brightness of the AC setting. When this happens, you can see that the screen is set to the brightness level set for the battery after you start in Windows 7. To resolve this problem, you will need to adjust the brightness of AC in power options plan. To do this follow the steps below:

  1. click on Start, click on Control Panel

  2. open hardware and audio

  3. Select the Power Options

  4 Select Change Plan settings

  5. under AC section adjust the Plan brightness to the desired level.

• Satellite L850-1FF - screen brightness hurt returning to record

  I am the owner of a Satellite L850-1FF (lots of gfx mem)

  Toshiba has enabled keyboard software tool that allows me to set the brightness to help
  FN + F2 + F3 to display darker or lighter.
  It works very well.

  BUT.

  If I close the lid (so the computer goes into power saving) and reopen the lid, the curriculum vitae of windows - the brightness is at max, or near max. The Fn + F2/F3 does not work. He just openes the view menu of the keys which is no setting - BUT does not work.

  Obviously, guessing a bug in Toshiba graphics card, or the keyboard driver adjust brightness tool.

  I wish I could restart the tool to see if that helps, but don't have any idea what program exe file it is.

  Toshiba - when will fix you this bug?

  I am very angry.
  I have to close all programs and restart windows now to make it work again.

  Greetings,
  Johan

  I assume that by virtue of being able to save, you mean standby, right?

  After waking from stand-by, can you change brightness level using parameters in some diet plan?

  It is not easy to say what can be the problem, but if you can change it in Windows power plan but not the keys of F I guess the problem is Toshiba specific tool.

  Otherwise, when you set the brightness level in Windows power management, it should not be changed after waking from sleep. That's what confused me.

  Can you please change the power management, set the brightness level and test standby? The same thing happens again?

  Hello

  You must install VAP and Support of Flash Card Utility for the FN keys works!
  Installation of VFR will not help you if you should not install Flash memory card Support utility.

  As far as I know, these two tools are not phone specific, so you can choose the VAP and the published Flash card for example utility for Satellite L500!

  I did it on my laptop and it worked fine!
