Lainu: Thank you very much for contacting the Intel® Graphics communities. We will do our best in order to try to fix this problem.

In regard to your question, is it difficult to explain why the brightness feature is not working properly after updating the graphics controller, it could be due to a compatibility problem with the driver installed. Just to let you know, the Intel graphics drivers are generic, meaning they might or might not work with your system, that is why we recommend to install the drivers provided by the manufacturer of the computer. Since processor works with Intel® HD graphics 4000, we can try to install the latest version of the graphics driver for that controller which is 4653:https://downloadcenter.intel.com/download/26813/Intel-Graphics-Driver-for-Windows-15-33-?product=81499 https://downloadcenter.intel.com/download/26813/Intel-Graphics-Driver-for-Windows-15-33-?product=81499 If the problem persists after that, to re-install the drivers or a BIOS update might be needed. In that case the best thing to do will be to get in contact with the manufacturer of the device directly. Also, as an option you can always get in contact with Microsoft directly to get further assistance on this scenario:https://support.microsoft.com/en-us/contactus/ https://support.microsoft.com/en-us/contactus/ Any further questions, please let me know.
