Please bear in mind that Intel uses generic video drivers for your Intel® HD Graphics 4000. Some graphics features added to your graphics controller may or may not work if you are using generic drivers, that is why Intel recommends customized drivers from Lenovo.

You could try using Screen Brightness from Power Options.

Have you tried manual driver installation?
