    Problems after Windows 10 update:- Fn +brightness & Lid Close


    After updating Windows 10 Home (to build 21313) on my laptop, I have the following two problems :-

    1. Fn + Brightness keys (F9 and F10) no longer work. Fn + sound keys and other such functions working correctly. I can, however, still use brightness slide bar in Settings to adjust brightness.

    2.When closing lid of laptop, machine will not sleep although power options have been set up for this. Machine will sleep when using the Start menu Power button.

    Both these problems do not occur when I boot to Linux Mint Live from a USB stick.

    I am suspecting a driver issue. Any ideas ?

    @dalchina,

    Yes, it is and I have already given feedback to M$ on these issues. However, if the meantime, I'd like to try and resolve these problems without having to resort to having to reinstall Windows so any hints or advice would be much appreciated.

    In general issues which may be related to driver updates the rule is to use the last available relevant driver from the manufacturer's site where this is applicable.

    Does yours have a driver download page? It seems quite new.

    I deleted the latest graphics driver (Version 27.20.100.9168) for the display adaptor (Intel UHD 600) in Device Manager then installed the original driver (Version 27.20.100.8280 - I had made a backup of all drivers when I first got the machine in June of last year).
    Problems remained

    Your device may have a utility/driver supporting hotkeys e.g. mine has

    All this aside- it could be there may simply be an incompatibility that can't be resolved.

    Machine does not have such a utility.......

    These functions previously did work. I tried rolling back update but issues remain

    For want of a better idea, some people found the first answer here helped:

    laptop - brightness control stops working after latest windows 10 update - Super User
    This is a list of workarounds that worked for some people :


    • Restore power defaults
      In Control Panel > Power Options, click Change Plan Settings and then on Restore default settings for this plan. Do this for all your Power Plans.
    • Disable Adaptive Brightness
      In Control Panel > Power Options, for your active power plan click Change plan settings, then Change advanced power settings. In the Power Options dialog, expand Display and then expand Enable Adaptive Brightness. Set all of them to Off.
      These setting are worth a look if you have then : Display brightness, Dimmed display brightness and Enable adaptive brightness.
    • Disable the Intel Power Saving Technology
      This setting is found in your Dell or Vaio Control Center. For more info see this article.
    • Disable the BrightnessReset task
      Open Task Scheduler and in the left pane expand Task Scheduler Library. Navigate to Microsoft > Windows > Display > Brightness (if you have it). If you see on the right a scheduled task called BrightnessReset, double-click on it, choose Properties > Triggers tab > Edit, then disable it and see if it works for you. A reboot might be required.
    • Run the Power Troubleshooter
      You may access it via the Windows 10 Troubleshooters Settings Page or run the following command directly to bring up the built-in Power Troubleshooter

      msdt.exe /id PowerDiagnostic
    • Registry change
      Use regedit to go to the key
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}.
      If you see any items named KMD_EnableBrightnessInterface2 or MD_EnableBrightnesslf2, set them to zero and reboot.
    • Power troubleshooting
      For further troubleshooting of Power Plans, use the built-in PowerCFG command line tool.
    Restoring power plans to default may relate to your sleep issue too.

    @dalchina,

    I've done quite a lot of searching for a cure for this myself and did not come up with a solution. I've attempted all the things mentioned above to no avail.
    If I can't find a solution in the next day or so, I'll have to bite the bullet and do a fresh install (something I was really trying to avoid)...................

    Cheers

    Hello @Janner Oyibo,

    If it does get to that stage, and as an alternative to a Clean Install, you could possibly try . . .

     In-Place-Upgrade - Repair Install

    Information & Tutorials:

    This is a Non-Destructive Process which keeps ALL your Apps, Programs, and Personal Data Intact . . .

    IMPORTANT: This is an extract from the Tutorial below . . .

    • You will only be able to do a repair install of Windows 10 from within Windows 10. You will not be able to do a repair install at boot or in Safe Mode.
    • You will need at least around 10 GB + what Windows is currently using of free space available on the Windows drive.
    • The installation media (ex: ISO or USB) must be the same edition and same or newer build as your currently installed Windows 10. If it's not, then the repair install will fail.
    • The installation media (ex: ISO or USB) must be the same base language (aka: system default language) as your currently installed Windows 10. If it's not, then you will not keep anything.
    • If you have a 32-bit Windows 10, then you must use a 32-bit ISO or USB.
    • If you have a 64-bit Windows 10, then you must use a 64-bit ISO or USB.

    > How to Do a Repair Install of Windows 10 with an In-place Upgrade

    Basically . . .

    [1] Download the ISO to the Desktop.
    [2] Right-click the ISO > Mount.
    [3] Open File Explorer.
    [4] Double-click the Mounted Drive to open it.
    [5] Double-click setup.exe.
    [6] Choose the Upgrade option.
    [7] Select Change what to keep.
    [8] Select One of the following . . .

    • Keep Personal Files and Apps.
    • Keep Personal Files Only.
    • Nothing.

    [9] Unmount the ISO by right-clicking the Mounted Drive > Eject.

    The ONLY downside is that you could possibly lose some of your personalizations.

    Recommendations:

    DISABLE:

    ANY Non-Microsoft . . .

    • Antivirus Software.
    • Firewall software.
    • Drive Encryption Software.

    I hope this helps.
