Guard reset screen brightness

• HP L2245w guard reset brightness

  I have a HP L2245w monitor who does not remember its settings, and I hope that someone knows how to solve this problem.  He really likes to have the brightness to '78' even if I want the brightness to '25 '.  Every day I find myself reset brightness so that my retnas are not burned, but after a year of this its becoming an old routine.  The monitor is connected via digital output, and I have a Setup dual monitor with a regular CRT using the VGA out (the CRT remember its brightness).  This is connected via a docking station with my HP 6910P laptop.

  I am sure that my monitor is in cohoots with my laptop.  For example, only 2 minutes ago, I keep my own business working on the computer, when the monitor suddenly goes black for about a half second, then instantly resets the brightness.  This makes me think that the problem lies in the way in which my laptop takes care of the installation of two screens, and the laptop is something to cause the monitor to reset the settings.

  Does anyone know how to fix this?  I'm hoping to find an answer before my progresses from anger to scream and break, I am sure that my colleagues would frown on.

  Then. I have a L2045w and things should be similar.

  If you think the lappy and watch you plotting against you, then you can go and break things between them. What you need to do is disable the DDC - communications that allow the lappy to change things like brightness, contrast, etc..

  Press menu OSD on the screen.

  Go to something like 'management '.

  Find what is called decision support DDC/CI (or similar)

  Disable this sucker.

  Let us know if it worked. Good day

• 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?

• Pavilion dv7-6163us windows 7 64-bit, the screen brightness will not adjust

  I reinstalled the latest graphics driver, the latest version of the BIOS and I still cannot adjust the brightness of the screens (screen).

  The indicator appears but is grey.

  Thanks for any help, Paul

  Update on the screen brightness controls; went into the BIOS and reset on off action keys.

  Restarted and there was no change.

  I then uninstalled the drivers for the monitor and rebooted and the brightness setting now works again.

  Thank you all, Todd especially for assistance.

  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!

• Set the screen brightness Satellite Pro 4200

  Hello
  I heard a key combination that makes possible the setting screen brightness.
  Is this true and what is the key combination?

  Yours sincerely
  Riedlz

  Hi Daniel,.

  Normal for thie keys Fn + F7 to increase brightness and Fn + F6 to decrease. But the different laptop models use different key combinations, so I would check your user manual to see which ones is correct for your laptop.

• C50-30 guard reset of the UEFI boot sequence

  Fedora 22 works fine on the C50-30 and starts fine with Secure Boot. However I still have to press F12 and select manually the Fedora shim on each (re) start, because for some reason any firmware guard reset the boot order to put Windows first.

  No matter if I move Fedora over Windows boot manager in the configuration utility, or efibootmgr allows you to change the order. After leaving the installation utility, the command is immediately reset to zero.

  I missed another adjustment here, or is this a bug in the firmware? BIOS version is O1XKT06AUS.

  It's a bug in the firmware. No problem if I rename \EFI\Microsoft to something else and make a new entry EFI (and adjust the GRUB configuration).

  Hello

  I have a Probook 6570 b with processor i5 here. He is running on W7 x 64 professional. As in all computers, we decided to replace the hard drive for an SSD. After replacing the hard drive and reinstallig W7 and drivers, there is a problem that I can't fix. It seems that I can't get the Fn keys for brightness screen work. The others work, volume gives a nice popup, evenso buttons additional display.

  Unplug the power supply makes the screen dim brightness. Who works. In the energy configuration screen, I can also adjust the screen brightness properly. Only the driver for F9 and F10 does not work.

  I don't know if it's related, but in Device Manager, I get an unknown device on a PCI bus. I have not been successful in finding drivers for this one as well. In the detailed tab, it says: * HPQ6000

  Thanks for responding!

• 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.
