• Cannot adjust the brightness after display driver update on Satellite L855-118

  Hello.

  I just bought a SATELLITE L855-118, with ATI graphics card today, it was between this and another of them, but I know that you have problems updating graphics drivers on a portable Sony.

  I did a restore point.

  So I uninstalled the ATI catalyst graphics card and then did a sweeper driver and rebooted and then installed catalyst 12.6, installed fine, but my screen went to the maximum brightness and I can't adjust, BRIGHTNESS osd is displayed but the brightness of the screen does not change.

  So I used my restore point.

  This time I crushed the catalyst 8.9 with 12.6 stock, still cannot adjust the brightness.

  Someone knows how to solve this problem.

  You just do a new installation of a Windows CD?

  If you have, you will need to install all the drivers concerned material, including graphics drivers.

  Click on start, run, then type devmgmt.msc and press ENTER. In Device Manager there devices not identified or marked as having a problem (marked with!)?

  Hi Jeff,

  The computer manufacturing must have created a partition on the disk or provided you CD to restore the computer to the way it was when you bought it. If you have a PC clone, then probably you need to reformat your hard drive and reinstall the operating system. If you have an OEM computer (example: HP, Dell, ETC) there is most likely instructions when you turn on/off press F11 or F12 to return the computer to the computer.

  Note: Do nothing until you have all of your backup data.

• 100 s-11IBY computer laptop (ideapad) - cannot adjust the brightness of the screen - windows 10

  Hello my f11 and f12 keys is no longer adjust my brightness. The gauge up and down, but does not change the brightness. I tried to update the graphics card in Device Manager, but he says that it is up-to-date. Same thing with 'Generic PNP Monitor' said that it is up-to-date. I wiped the computer clean and 'reset' and reinstalled windows and it still does not allow me to adjust the brightness of the screen

  I'm not incredibly intuitive with computers, but I followed the instructions as much as I could find during my research online with nothing doesn't.

  Initially, the problem occurred when I used out of ignorance a program to install the drivers it says have been exceeded. After that, my audio stop working and my keyboard stop working entirely. After resetting the computer and windows resettled, the only question that remains is the brightness of the screen not being able to be adjusted.

  This drives me crazy, can anyone help me? I would be very happy! and please let me know if you need more information regarding my laptop. Thank you!!

  I thought about it. My drivers intel had to be installed since I reinstalled windows. I used the utility of intel and updated driver to update the graphics card update

• Yoga 2, windows 8: cannot adjust the brightness or connect to external monitor

  I have been using my yoga 2 with an external monitor via micro-hdmi port, but a week ago, it stopped working. The monitor does not recognize laptop. In addition, I can't adjust the brightness of my laptop screen, the keyboard, or in the control panel in windows. I think that this problem started after a windows update, but I'm not entirely sure. Does anyone know a fix? Thank you!

  Dear rustforian

  Welcome to Lenovo forums

  For external monitor, please try another cable and another screen if available or check if the cable and the screen work fine with other devices

  For brightness problem please try to go to under view Device Manager right click on the Intel driver cards and choose Properties
  On the driver tab, click roll back driver, if it is dimmed, try to download and install the driver from the link below

• Laptop HP 15-g010nr: cannot adjust the brightness of the screen

  Recently, I was unable to adjust the brightness of the screen on my laptop. I tried to adjust by using the F2 and F3 keys and also in the settings but the brightness remains the same. When I use the F2 and F3 keys, not only the brightness does not change, but the bar that is supposed to go up and down depending on how adjust you the brightness does not move. When I try to fit it in the Middle, I can move the bar but the brightness does not change. Currently, the brightness of my screen is stuck in almost the lowest setting.

• Satellite L500 - cannot adjust the brightness of the screen

  I have a L500 - came out with Windows 7. I can't also adjust the brightness - the external monitor is fine. 17 other laptops in the same school are fine - just this one.
  The FN key doesn't seem to work - the laptop screen is so dark, that it is not readable.

  I didn't know all the answers that respond to that?

  Hi redmg,

  The FN keys are controlled by value added and Flash Cards Support utility package. So if you can use t FN keys correctly reinstall these two tools of Toshiba. You can download on the official page of Toshiba:
  http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

  But remove older versions before installing the new versions.

  After that all FN keys should work properly again.

• 15 - r254nu:. Cannot adjust the brightness on Windows 8.1

  So I tried different ways to resolve this issue, but again the light cannot be turned on/off. Help, please!

  

  Hello:

  There are two Intel driver links to the choices on your laptop support page.

  I explored the folder of the driver of this driver file to support your laptop and driver page, and it is suitable to use driver.

  This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

  File name: sp69589.exe

  The hardware ID for the Intel graphics card in your laptop must be one of these...

  ;=====================================================================
  ;    Windows 8.1 install
  ;=====================================================================
  [IntelGfx.NTamd64.6.3]

  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_220F103C
  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2213103C
  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2210103C
  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2214103C

  You should see a device from Intel HD graphics instead of the graphics card base of Microsoft, and unless you can get the graphics driver to install you will not be able to adjust the brightness of the screen.

  Is the above driver do not install the Intel graphics card automatically, try to install the driver manually by navigating to the folder of the driver that is created after running the above file.

  Confirm that the hardware for the Intel graphics card ID matches one of the above since the driver installation information file that I posted.

  To find the ID of the hardware, Device Manager, click the graphics card Microsoft Basic.

  Then click on the Details tab in the upper part of the window Microsoft Basic graphics card.

  Now you should see a drop-down list of property and it is set by default to the Description of the unit.

  On this list and select the 3rd point (Hardware ID).

  Confirm that the hardware ID, you see there is one of those listed that I posted.

• HP Pavilion Dv6 Notebook PC: Cannot adjust the brightness/contrast

  Hi all

  After a new installation of Windows 7 64 bit Home Premium on my HP Pavilion dv6, I find that I can't adjust the brightness/contrast of the screen. Initially, I had installed a generic pnp Monitor driver, but after reading a solution which recommends to uninstall, I did, but to no avail. I have also tried installing HP Support Assistant, scanned my laptop computer for outdated drivers and have installed the recommended drivers, but I am always faced with the same problem.

  If you provide me with any details on my laptop, let me know.

  Thank you.

  Hello.

  I realized later that I had 215 updates of windows install. After I did, the problem solved itself, but I think that among the updates has been one for the graphics driver.

  Thanks for your response!
