  Sharing my experience with all T400 Windows 8 users.

  Windows 8

  Sentabrina custom W7 with old Catalyst installer worked for me as well, on Windows 8 x64, just follow the instruction.

  Windows 8.1

  When I upgraded to windows 8.1 everything FALLS apart if you install the lenovo power manager 6.32 or 6.34. After clean upgrade to 8.1 and then install the power manager, the system will refuse to boot citing some security doesn't match. I had to clean reinstall from windows 8->windows 8.1 twice.

  The solution is to NOT install the power manager. Just clean install windows 8->8.1 then Sentabrina custom W7 drivers. After that, head over to ATI and download the latest drivers 8.970.100.7000 dated 16/11/2012 for the T400 Mobility Radeon HD 3400 Series drivers (Windows 8). After installation, Switchable graphics is active which I guess is now build into the Windows 8.1 (hence no requirement for lenovo power manager).

  However, the latest drivers seem to have a bug with secondary monitors and boot up with a 4:3 screen on my 24 inch Samsung widescreen monitor 1920x1200 resolution. I have to manually expand the screen using the ATI catalyst control center everytime I boot up.
