So I got my new y460p and i needed to reformat it. I installed all the necessary drivers, BUT, even though i installed the software, the OneKey rescue system button, the power management, and OneKey theatre cap sensor buttons dont work anymore! (The cap sensor buttons for volume control dont work either!) Everything was working fine before i reformatted the system so it must be a driver problem. Furthermore, in device manager it shows an unknown device (im assuming this is the device that needs the neccessary driver) and I I didnt delete the OneKey rescue partition so that's not the problem. Also the slideNAV thingy works fine. I went on the Lenovo support website and there arent any drivers specifcally for these buttons.
can you tell me how you re-installed operation system? by using one key recover button? for the buttons ( function keys ) you need to install power management. install it, if it doesn't work, please, provide unknown device id such as pci/xxxxxxx.
