I got it working now :) Install exactly in this order: Download all sony drivers for Vista Instal Vaio event service Reboot Install Sony DLL Utils Reboot Install Sony shared Library Reboot and it should work
S4 sleep works fine, unlike S1 and S3, ( resumes in 7 sec. and that's just fine ) only problem is that I have to push the power button :( It would be nice to be able use remote.
Lucky you, didn't work for me :( My z545 wakes up but there is no video signal, only fan spinning and HD will spin as well. It will not respond to anything. I have to hold the power button to shut it down. Frustrating since everything else works perfect.
