Ajustment of brighness not working

Please help me with my trouble. i have Lenovo sl 500. I've decided to update my windows vista home basic( that was built-in my notebook) to windows 7. All troubles were solved, but i cannot change the level of brightness(pressing Fn +home/end ) the other combinations with the button "Fn" are working. Maybe i need a driver? i found  two drivers that not capable with windows 7 maybe connected with my problem. Please can you name this driver or help me to solve this problem. Thank you

If this after standby/hibernate, try closing and opening the lid. This sometimes helps for me. For this issue, see also this topic.
Also, make sure you have all needed drivers installed (e.g. the system interface driver, hotkey driver).

  • Ambient light senor/auto brighness on iPad 3 not working

    I updated my iPad 3 to iOS version 6.1.3 yesterday. At first I noticed that the brightness control would move on its own. Today, I noticed that the auto brightness has no affect on the screen lighting.
    Has anyone seen this before, or have any suggestions?
    I did a couple of resets and still not working (hold power off and home button for 10 seconds) until unit shuts down.
    Thanks bunches for any suggestions.

    hi
    since you have already tried the basic troubleshooting, no other way rather than taking to an Apple store

  • Satellite C50D-A-138 backlight not working

    Hi, I am having a major issue with my laptop. The backlight for the display will not work. I can only faintly see the picture. I tried adjusting brighness, no joy. It outputs fine to a monitor. I have tried replacing the screen and the connecting ribbon but the issue still presents itself. Does anyone have any ideas??? I am at a loss.

    Hi
    Connect external monitor and check if the same display problem would appear on the external display.
    In case everything would appear properly on the external display, the problem must be the internal display panel.
    The notebook’s display panel seems to use a LED backlight as the light source.
    So probably the display’s backlight doesn’t function correctly. In such case the display panel must be replaced.
    You should ensure that you are using compatible panel because many notebook displays support different technology (TFT panels without backlight and display supporting backlight like the one build in the C50D-A)

  • Satellite M35 - Brightness Not working with WXP SP2

    After formatting and installing XP SP2, Brighness function keys do not work. Can anyone please point me to what type of drivers I need to download to get the Brightness working? I tried to install Power Saver from Toshiba site BUT I get error messages. Nto sure if this driver is for Service Pack 2 of XP.
    Any assistance you can give in getting the M35 Satellite Brightness working with XP Service Pack 2 would be appreciate.
    Thank you in advance.

    Hello
    Try please to install Toshiba Hotkey Utility for Display Devices for Windows XP. I dont know if just this utility is responsible for that but fact is that you should install all Toshiba specific stuff and combination of those tools result with full functionality.
    If you dont have Tools & Utilities CD please check Toshiba US download page and there you will find everything you need.

  • Yoga 2 13 brightness keys not working - it was TeamViewer monitor driver

    Hello, I have two Yoga 2 13's - I think both the 59403750 model. Both have the same specs.
    In one of those Yogas the brightness keys - "F11" and "F12" - do not work and it is full 100% brighness all the time. In the other (good) Yoga they seem to work OK - at least I can get the brighness down a few notches.
    When I press and hold the Fn key to get F11 or F12 to work the *seem* to do what F11 or F12 would do normally - e.g. in a word processor or browser. So it seems maybe just the brighness function of those keys are not working.
    Lenovo has calimed that this is not a hardware problem and they are not responsibile for it under warranty.
    I have done a little reading some time ago and seen something similar that was maybe fixed by installing updated video drivers. Well, that did not work - as of a couple months ago. At the time I also updated the BIOS - again no luck.
    Any ideas /inputs you might have are appreciated. Thank you.
    Solved!

    scf /scannow 'found corrupt files but was unable to fix some of them. Details are included in the CBS.Log' and then something about 'not normally suppoorted in offline servicing'.
    I'm reading from MS Use the System File Checker tool to repair missing or corrupted system files and in the mean time I'm also doing a chkdsk /r just to make sure that's not an issue before I start trying to repair any files. Both were refirbs (still under warranty) - so who knows about the HDDs. Luckilly I may have the other one to pull files from if necessary - if it is something that easy.
    It's been doing this since pretty much the day I got it. I've never seen it work right on this one.
    I appreciate the tip to factory restore but that is always the last option IMHO. That's a lot of time for me to get this thing back the way I want it. There has to be a fix for this silliness - I'll keep working on it and write back when I know more. Thank you very much for the help. If you think of anything else let me know.

    Please help me as I want to use these control key on my laptop's keyboard.

    Hi:
    Did you install the chipset and graphics drivers?
    You won't be able to dim the brighness without having those drivers installed.

    Hi
    The WF should also trigger if i add the Partner function in UI.If i change any Attribute the WF triggers but i dont want to change the attribute when i add the partner function.
    If i have only one event for WF that is Partner Change the WF will not trigger it for the 1st time when i save the UI. But next i come to the same saved doc and add a partner function then the Wf triggers.
    So this means that Partner change is active.
    the issue here is i need to trigger the WF on , the 1st time i save the UI, for which i wil be using Attribute Change and next time when i come back to saved doc the and add only the partner function and no changes are made to attributes the WF should again trigger.
    Thanks

  • IPhone 4 Voice Memos not working/saving

    Hi there,
    I'm having trouble with my voice memos too. Up until yesterday they were working fine and now, even though the record button works, the stop button does not and I can only pause them. Worse again is that the button to go into the menu to view all voice memos is not working so I can't play them from my iPhone and nothing new is saving to my iTunes. Please help!

    I've always had the "Include Voice Memos" option selected. I think that only pertains to syncing voice memos from iTunes to the iPhone after it has been copied to iTunes. It has to be the new OS/iTunes not communicating that new memos have been recorded. For some reason they won't sync when I want them to, and then a few syncs later they magically appear.
    By the way, I'm VERY comfortable with the iTunes and iPhone systems. I've been using iTunes for 5 years, and I've been recording class lectures with the iPhone voice memo app (and another app) for a couple years. It's not an error of not seeing that the memos were added; they don't exist in my library or music folders.
