• 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...

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

  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!

• The display brightness is automatically defined by content screen brightness?

  Additional for my other problem with the brightness of the screen I also have this question:

  Battery operation, it seems that the display brightness is automatically adjusted by the lightness of the contents of the screen.

  For example if I start a program with a dark background display becomes a little darker. On the other hand, a lighter background makes the screen a little clearer. It is not strong like a tap on F7 or F8 - just a little bit.

  Of course, this is a nice feature. But for me who use many applications as it is a bit annoying.

  Can someone give me a tip where I can disable this feature? Found nothing in the settings of the energy.

• Screen on the Libretto 50ct problem

  Hello!

  My L50 has a problem with the internal TFT display. It starts and runs normally and I can control using UltraVNC or by attaching an external monitor, so it isn't a problem with the graphics chip.
  But the internal TFT remains mainly black - after ignition, it gives a short flash showing noise colored with a darker in the middle of about a second task, then becomes almost black and shows that vertical lines brighter and darker than the change in appearance a little whenever the content of the screen is changed.
  The * backlight still works * and on very rare occasions, the screen * lights correctly * and then shows no signs of a problem until I restart.

  Since your laptop is not very useful when you can't read the screen, I used it as a small, low-power 'server' for the last year and a half, which did not cause any change in the situation of the screen.
  I tried to re-allocation of places each connector who may be involved - the great connector of the main card for the Group of experts, as well as all connectors that leads from there to the module Sharp TFT itself and the connectors inside the module. I noticed a few connectors which, when unplugged, causes a white screen Uni, but otherwise, the problem persisted.

  It would be a shame to withdraw from this cute little thing in a drawer just because of the screen.

  Does anyone have a suggestion as to what could be the cause? If I knew for sure that would solve the problem, I could buy a replacement screen or wait an article damaged on ebay that has a working screen.

  Best regards and greetings from Bavaria :)

  Hi Tobias,.

  Man, it's a pretty old baby. The last time I had something similar in my hands was 4 or 5 years ago.
  In this case, I would say that the screen and the cable must be exchanged because the jury should be OK.

  Why the screen and the cable? Because if the connector on the screen has some damage then the cable she also.
  I guess that the controller of the screen has a few hitches, maybe a touch loose?

  Hope you will restore your machine and should not be retired. :)

• T420s - screen brightness increases and decreases

  Hello

  I noticed on my T420s that changes of screen brightness according to the image on the screen.

  For example:

  -I'm looking at some site with black background and gray letters

  When I pass screen for my outlook or for example firefox with this forum which first minutes white white background is gray and then it becomes whiter and whiter until after about 2 seconds, he moved.

  I thought at first my eyes question, but it is certainly behavior from my laptop.

  Anyone with the same problem? Can do this set by some software/Power Manager tweak?

  Do you use your laptop on battery when this happens?

  It is a setting I believe you can disable in the Intel graphics settings. Mine does the same thing - it's supposed to save energy.

  • In the menu of the interface that ensued, choose Browse my computer for driver software.

  • In the next screen, select Microsoft Basic graphics card in the list under the section Show compatible hardware . Then click Next to continue.
  • Windows must now install the selected driver and the display driver problem should no longer affect your screen brightness function. You should now be able to increase or decrease the brightness of the display without hassle.
