Contrast Adjustment not Working Consistently on Acer Switch 11

I recently purchased an Acer Switch 11.  I noticed that I wasn't able to adjust the display contrast, using the left/right arrows and "FN" key.  Through a chat session, an Acer technician recommended that I reinstall the Intel VGA Driver through Acer Recovery Management.  I followed his instruction, and it worked.  However, later I noticed that I could not longer adjust the contrast.  I could see the indicator move up and down in the upper left-hand corner of the screen, but the contrast wouldn't changed.  I once again reinstalled the Intel VGA Driver, and it corrected the problem.

 

After re-installing the driver a second time, I decided I would leave the tablet plugged into the keyboard.  Every fifteen minutes or so, I would unplug the display to see if the contrast changed.  Based on my settings, it did change as desired.  I did this for several hours.  Later, I decided to remove the display from the keyboard.  Initially, I was still able to adjust the contrast.  However, after 10 minutes or so, I no longer could make adjustments.  At that point, I placed the display back into the keyboard dock.  I tried to see if it being locked into the keyboard was required in order to make contrast changes.  It still didn't work.  I then reinstalled the Intel VGA Driver and corrected the problem.  I have kept it plugged into the keyboard, and I can still make adjustments.

 

Has anyone encountered this issue?

    Thanks for the quick response!  I have the SW5-171-80KM model.  How do I check the BIOS version?

    Press and hold the Window logo key and tap X on your keyboard to open device manager.
    Click Run and type msinfo32 in the Run box and hit the Enter key.
    In the System Information window, click System Summary and locate your current BIOS Version/Date to the right.

    I had the 1.03 version of BIOS.  I ugraded to 1.04 and confirmed it was completed.  I also downloaded the Chipset driver.  How do I confirm that this was completed?

    You need to just restart your compter to make the changes effective and check if the issue has been resolved.

    Unfortunately, this didn't work.  It worked initially, but once I closed the lid on my laptop and reopened, I could no longer adjust the brightness. I could see the indicator move up and down in the upper right corner.  Plus when I unplugged the laptop with the indicator displayed, I could see the setting drop.  However, the display didn't visually change.

    I rebooted my computer, and left it open all day.  Adjusting the brightness wasn't a problem.  It worked when the tablet was either in the keyboard dock or removed.  I logged out several times and back in, and I was still able to adjust the brightness.  However, while the tablet was still on and locked into the keyboard, I decided to close it up while it was still on.  I waited about ten seconds and then re-opened the laptop.  After logging in, I could no longer adjust the brightness.  I had to reboot the computer in order to restore the adjustment capabilities.  

     

    Could others who have an Acer Switch 10 or 11 see if they encounter the same issue when applying this test?
