• T510 brightness adjustment sometimes does not work

  I had last nNvidia drivers NVS 3100 M.

  Anyone know any solution for this problem?

  Thank you

• AT200 - drop in brightness problems

  Hello world!

  Recently, I noticed that there is a problem with the brightness of my Tablet (AT200-100).
  When I use it for a while, the brightness begins to fall down by itself.
  Not because of the 'auto' function, because the ambient light continues to be the same.

  The problem is that the "brightness" that I can select continues to fall down, until it reaches approximately 10%! After that, I can not select again more than 10%, the brightness slider does just not go right, so I can only choose from 0% to 10%.

  As I saw that, I saw in the 'quick-settings-clock-menu"how the brightness slider was falling down and down, without being able to restore it to its original position.

  After a while (a long time) with the suspended shelf, I can choose the brightness once again without any problem...

  Moreover, recently the Tablet starts to become much warmer before, or at least that is my impression. Maybe the heat is the cause of the problem?

  Everyone is having this problem?
  I'll try to start to uninstall apps, just in case one of them is the problem.

  Any idea oder?
  Thanks in advance!

  Hello

  Unfortunately, I m not AT200 owner therefore cannot share my experience with this device, but it would be interesting to know if one of the installed app causes this problem
  Would be interesting to know if factory reset would solve this

• 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.
  Which is really strange.
  It works correctly when you change the brightness level in the plan directly to settings?

• Satellite A100 (PSAA9): Win7 + setting screen brightness problem

  Hello

  I installed Windows 7 64 bit on my toshiba A100 (psaa9) machine and I cannot change the screen brightness more.

  It's always a maximum brightness. FN key doesn't work, and neigther Control Panel I can change the nvidia manually through the brightness. NVIDIA driver is 7.15.11.7967, which is installed automatically with windows.

  I have read suggestions on value-added package to install, but there is no package like that for my model.

  How can I solve my problem?
  Thank you

  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!

• Brightness problem with aspire switch 10

  Hi all

  I have a gene with a switch screen aspire 10.
  The brightness level is constantly changing. It is not dependend on the ambient light, because I turned off Adaptive brightness. (When I put a flashlight on the light sensor that does nothing).

  For example: sometimes when I switch between the metro and the desktop mode. Notable stage screens turns a bit more or less clear. It also happens when you watch movies, opening programs, almost always when the image changes.

  Does anyone know a solution to this?

  Kind regards.

  To resolve this problem, I did this.

  On the desktop, right-click. Properties of the graph. Power. I turned off the screen of the energy saving technology.

  I hope this works for you also.

• Screen brightness problem

  Hello

  I have a problem with my brightness of the screens. The brightness keys does not work all suddenly and in charms in brightness, I can move the cursor, but nothing happens. My screen is stuck at a all time high. I have a Paviion Windows 8 Hp TouchSmart 15 Notebook PC. I tried disabling and uninstalling my HD graphics card, but the problem persists... What do I do?

  Hi Naruto101,

  We have to remove TeamViewer. Check the Add/Remove programs and make sure that all software has been removed from it. If we can't be deleted from there you can do a system restore to an earlier date until it has been installed, using Microsoft System Restore (Windows 8).

  If you are unable to uninstall with it then you need to get in touch with the Forum of TeamViewer for instructions to uninstall.

  I hope this helps, keep me posted on how things are going.

  Good luck and have a great day!

• Dell XPS 13 9333 screen brightness problem

  Hello

  Another problem with my new Dell XPS 13 (model 9333) - for any reason, during loading or no, changes in brightness screen without saying me things to do (she just made right now by writing this sentence!).

  Any ideas on why this is happening? It's kinda like a light automatic on a smartphone but much more random thing! It really starts to wreck really my head.

  Any help appreciated no matter how silly it sounds!

  See you soon,.

  I found a setting called "enable adaptive brightness" which seems to turn off this nonsense.  On Win8.1, it is:

  Power options > change Plan settings > change advanced power settings > display > enable adaptive brightness
