• 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...

  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!

• 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.

  Kind regards

• Laptop 17 HP envy flickering screen? (in fact some troubleshooting)

  It flashes when I click on an item or open a folder. Also, he goes crazy when I put on a video.

  Things I've done:

  Updated drivers.

  "Hold down the power button / stop" method.

  I have clues:

  1. I remember when I received the laptop, he would always sparkle in exactly the same way when a charger that has been plugged in was too weak (can leave message too low) and change the charger always fixed.

  Now I still have the same charger (I have 3 hp and 1 dell Chargers at home that match my laptop) and none of them seem to be "pretty" (x 2 65w 1 x 60w and 120w x 1).

  (2. another funny is that when I uninstalled my drivers Ati Radeon HD5850 completely, there is no flickering, but obviously, I need to have what I use this laptop strictly for the games)

  3. the screen refresh rate is 60 Hz and not possible to change.

  4. There is NO flickering on an external display (tried two televisions, both have a little clicker)

  5. you say that it's a hardware problem, but I actually somehow got to operate the flicker-free earlier this evening and are stayed all night play and it did not cause me any questions. It was working fine.

  6. sometimes the PC freezes (could this be a battery problem? because I currently does not use one as mine are broken and I'm waiting for a new ship)

  7. I recently had 2 blue screens of death. A when installing the ATI drivers and another that I don't remember.

  Sorry for the wall of text, I tried to make it easy to read

  Hi wallyson691,

  Welcome to the HP Forums!

  I would like to take a moment and thank you for using the forum, it's a great place to find answers. You have the best experience in the HP forum, I would like to draw your attention to the Guide of the Forums HP first time here? Learn how to publish and more.

  No need to apologize for the amount of text.  It is always better to have too much information then is not enough.

  It is very useful during validation to include your exact model of HP laptop and the operating system you are using.  How can I find my model number or product number?

  I noticed that you have a flickering screen problem and you have successfully updated the drivers but it has not fixed the problem.

  When you have uninstalled the Ati Radeon HD5850 the problem disappeared.

  You had this problem before, and it was linked to the power.  You have tried different adapters but no change.

  Have you tried a different outlet?

  You did all your Windows updates?

  Have you tried HP Support Assistant to help with updates and issues running?

  Did you run MS fix to try to solve the problem?

  Here is a link to the display quality problemsthat can help.

  If you think it may be a conflict in the origin of the problem, you can try using Microsoft System Configuration (Windows 7) to find out what is the cause.

  I would like to start a test of material just to rule out this possibility.  Test of hardware failures (Windows 7, Vista)

  You could try a restore to where he worked, using Microsoft System Restore (Windows 7)

  You can try to install the original driver to see if it helps. Using the Recovery Manager to restore the software and drivers (Windows 7)

  You can consider to recover to factory.

  Performing a recovery of system HP (Windows 7)

  During the recovery process, you will receive a prompt to back up personal files to avoid loss.

  Restore files that have been supported to the top using HP Recovery Manager (Windows 7)

  I hope this helps.

• ProBook 6570b: screen brightness works do not, the unknown device on PCI

  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!

  I can't give you the graphics driver because your laptop can come with 2 different graphic configurations.

  Try typing the screen brightness in the dialog box search/Cortana.

  It opens the Power Options window. At the bottom of the window is a screen brightness slider.

• 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.

• Smart touch 610-1010UK Office: flickering screen on Touchsmart 610

  During the evening of 11/11/15 the flickering screen started. The mouse moves the cursor, but nothing does. F1, F8, F10, and F11 repeatedly pressed when starting up do not appear all the screens.  I see others have screen similar flicker. Help would be appreciated.

  Resolved - on the Microsoft Forum, we thought that Windows Update KB3097877 on Windows 7 might have caused the flickering on the PC.  Windows have now pushed another version of KB3097877 for this problem.   The good news for those whose parts are automatic update of Windows is that all you have to do is turn on your computer and put up with the annoying flicker until the new update gives you the logon screen.

  If any good came of this, is that we should remember to save regularly.

  Hi @Sherzad1,

  Please try the alternative below:

  • Go to Start Menu > search and type "Device Manager", and then launch Device Manager
  • Scroll down to the entry of graphics cards in the list of devices and expand the option. Right-click on the display drivers and choose Update driver software from the context menu.
  • In the menu of the interface that ensued, choose Browse my computer for driver software.
  • Then choose the option "Let Me pick from a list of drivers on my computer"
  • 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.

  Kind regards
