Update: 1) Download drivers from
Sony | Download VAIO Drivers choose locked drivers
2)Install all drivers, specially :video (nvidia), audio, network, wireless
and the driver
Original - Sony® Firmware Extension Parser Device
(that's it the special keyboard driver). the restart
3) then install sony shared library
restart
4) and vaio event service
and restart
5) and sony notebook utilities (it include panel, battery checker, event service...)
and (guess that) restart again.
if fail then repeat 3) and 4)
btw, i did with windows server 2008 r2 64bits
In my case, it fail the bluetooth and somethings about incorrect battery (but i disable such functionality).
ps :Sony says that YOU MUST INSTALL sony shared libraries before sony notebook utilities, so apparently the order of 3) and 4) is irrelevant but 3) must be before 5)
