    Yes, NVIDIA Optimus. Driver versions as reported by inspecting the display adapters in Device Manager :
    Intel HD Graphics : driver 8.15.10.2900 (26/11/2012)
    NVIDIA NVS3100M : driver 21.21.13.4200 (18/10/2016)​
    I seem to remember a whole bunch of trouble getting some aspect of the display to work correctly after the 2017 Fall Creators update (not sure why I ended up trying to reinstall one of the drivers - think it was the NVIDIA one), but somehow it did eventually install and work. Not sure why the 1803 update has broken it now.

    A similar problem with the 1803 update has been reported by someone on the Lenovo forums for a T410 with Intel Graphics.

    The BIOS contains two relevant options, "Graphics Device" and "OS Detection for NVIDIA Optimus". I left the latter set to "Disabled" (otherwise it would automatically use Optimus if the OS supports it), so I definitely had control via the "Graphics Device" setting.

    Using the Intel device, or Optimus gave the same result - presumably for both the Intel adapter runs the desktop display, and brightness control is broken (in a similar manner to the report on the Lenovo forum referring to an Intel-only T410). Obviously the Optimus setting should allow the NVIDIA adapter to be used for select applications, as controlled by the NVIDIA utility.

    Using the NVIDIA device initially resulted in an incorrect display resolution for the LCD after boot (aspect ratio was wrong), but after a little while the system recognised the adapter and the correct 1440x900 resolution appeared. Brightness control worked fine.

    So, the Intel adapter with the driver I mentioned above is broken under the Windows 10 1803 update. I have not yet tried the driver the Lenovo forum suggests may work.

    Just updated my T410 (Nvidia version w/o Optimus) to Win 10 version 1803 and all is good: Screen brightness control works, volume buttons and some Fn key combinations work, didn't break a single driver too.

    Regarding loss of screen brightness control in Westmere generation (1st-gen Core i3/i5/i7) laptops w/ Intel HD Graphics after updating to 1803, my 2740p also suffer from this, while my E5510 doesn't.

    Updated my post a couple of posts above to reflect some investigation on my part, and clarify things a little.

    I would update both your Nvidia and Intel drivers as both are extremely outdated. That should fix your brightness issues. If that doesn’t work look for and updated BIOS for your system. Updated to the newest version on the support page.

    I'm fairly positive both drivers are the latest, or at least close to the latest version.

    In case you don't know:
    • The latest graphics driver for this Intel HD Graphics (aka GMA HD Graphics or Ironlake) is 8.15.10.2993 (for Vista and 7), in Win 10 you'll get 8.15.10.2900 by default.
    • Support for Tesla generation Nvidia GPU has long ended (NVS 3100M is about the same as GT 310M), the latest driver package that supports them is 342.01, which was released in late 2016.
    To be honest, I'm not surprised by such antics from this iGPU, it has started acting up beginning with version 1607, where you'd get a black screen flash every time after waking up the screen or waking from standby. It was so irritating but thankfully it was gone in version 1709.
