  Hello.

  I have 15 inch MBP mid 2015. I installed windows 10 in this regard through bootcamp, it was working fine except that I saw apple update that need to download updates, one was for the size 300 MB AMD graphics card and something small about 3 MB for the best work of the material I think.

• 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 mean that you can not use the Fn or Fn + F6, F7 button combination?
  Do other combination works properly?

• Qosmio G30-140 - cannot adjust the brightness of the screen on Windows 7

  Hello

  I installed Windows 7 on my Qosmio G30-140, but I can't adjust the brightness settings.
  Instead of allowing me to place the cursor on any position, I want that I'm stuck with only 3 steps which elect to.
  The last of them is way to bright and my eyes keep tear having to deal with this crazy amount of white, especially on white background.
  The other two are very, very dark.
  What is going on? I installed the right Nvidia drivers.
  Also, I can't adjust the brightness using the FN keys on my keyboard. They simply produce no result at all.

  Need help appreciated, I can't work like this.

  Thank you!

  Hello

  The brightness of the display can be controlled by the FN + F7 and Fn + F6.
  I think you should install the VAP and buttons of the Support of Flash memory card utility in order to get this to work!

  Check the added value Package and Support Flash Card which are released for Satellite L500 utility or new models of laptops.
  In my case it worked!

• 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

• Cannot adjust the brightness of the screen after the new installation of Windows 7

  I have a Pavilion dv2945se notebook. I have completely updated the Nvidia geforce 7150 m drivers. My laptop came with Windows Vista Home Premium 64-bit, and I did a new install of Windows 7 Home Premium 64-bit. I can't adjust the brightness of the display. I narrowed down the problem to the generic PnP Monitor driver. How can I solve this problem?

  Edit: I mean "impossible to adjust the brightness of the display" that every time I go into power options and trying to use the cursor, Windows Explorer crashes. Also, my fn + F7 and F8 keys light work before I connect to windows, but not after. I think that something will charge when I connect to windows that is causing the problem. So I went in Mode safe, but then all that allows to control the brightness has not loaded when I went into safe mode, which was not helpful. I also went into MSConfig and disabled all startup programs, but again, I have the same problem. The brightness of the keys work before connect you to Windows, but not thereafter.

  When I turn off the device generic PnP monitor (1) can't adjust the brightness at all and (2) the Power Options window stops freezing. That's how I've narrowed the problem to the generic PnP Monitor driver.

  I finally solved this by uninstalling the driver for the ALPS touchpad. Because there are no Windows 7 drivers for my laptop even though it is listed in the models capable of upgrading to Windows 7, I used Windows Vista touchpad drivers. It was the cause of my problem with brightness adjustment. I don't know why it worked, but I've narrowed it down by disabling all processes start and then from their one at a time to see what caused the problem. As soon as I started Apoint.exe, I started to have problems.

  Now, I just have to find a way to disable the touchpad tapping without the ALPS drivers.

• Cannot adjust the brightness after installing Windows 10

  Hello. I have a Dell XPS 15 L521X.   Recently updated to Windows 10 and I can adjust is no longer my brightness upwards or downwards.

  Now the screen is quite low.  I'd say about 30-40% brightness.  10 widows I found about 5 different places to adjust your brightness and I made sure all of them have been set to 100%.  I have my power plan to high performance and I went into advanced settings and turned off Adaptive brightness and made sure that the brightness of the screen the two Dim brightness set to 100% on battery & are plugged.  Rebooted and still dim.

  My question is, on Dell laptops, Windows has full access to the brightness control?  Or Dell replaces Windows with their software customized for the display settings?   When I bought this laptop in 2012, the software, at the time, was called Dell QuickSet.  What is the responsible application of brightness of the screen control?  And is it necessary?

  Thank you

  Mike

  I am also having this same problem. My brightness has been set at max after update and it hurts my eyes. I did it... Control Panel > Device Manager > graphics cards > Intel HD Graphics 4000 > pilot > Update Driver > Browse my computer > let me pick. Choose Microsoft Basic graphics card.

  After doing this, my problem was solved, and I was able to adjust the brightness of my screen again. BUT if you play games on your laptop, it will cause display problems in your game.

• Windows 7, cannot adjust the brightness of the screen.

  I just upgraded from Vista to Windows 7 on my laptop Acer Timeline 5810. Now I find that I can't adjust the brightness of the screen by pressing the "Fn" and arrows. I used to use this function a lot and my screen doesn't seem as bright as it did before installing 7.

  I can fix by going to control panel > display > brightness etc, but I would prefer if my normal keys were working.

  Any ideas, anyone?

  It is a function of the keyboard drivers custom on all laptop computers the most. HP called launch fast, not sure of Acer.

  You must log in to the Acer website, search for your model and see if they have a keyboard driver for your model laptop for Windows 7

• 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.
