ThinkVantage and sound mute button malfunction (T400)


I have a ThinkPad T400 with Windows 10 64-bit. Everything is OK, but the ThinkVantage button works only at startup (to interrup normal start and get into the BIOS?), but in normal system interface it doesn't. The same are the volume and mute keys - keys of volume up/down works (without any indication on the screen), and the mute key mutes the sound only "inside the computer", without muting sound in Windows /this has to be done manually/.

So, is there any possibility to install any drivers to make it work properly? Thanks.
