Hi, thank you for your fast reply.

I tried to remove both kernel parameters (acpi_backlight=vendor and
acpi_sleep=nonvs) but problem persist. (see attached file).

In 12.04 (and in 11.10) I used a patched sony-laptop.ko module (please refer to 
http://www.absence.it/vaio-acpi/source/patches/ and 
http://code.google.com/p/vaio-f11-linux/issues/detail?id=6 ). It improved the 
management of energy savings through better driver support for backlight and 
environment light sensor with my Vaio. I believe that I introduced the kernel 
parameter acpi_backlight=vendor after  applying this patch or, however, to 
improve support to brightness. 
Just for your knowledge, after upgraded to 12.10, I could not apply this patch 
to current kernel (was incompatible with 3.5: patching result in a reject file).

The acpi_sleep=nonvs kernel parameter was not present when i used12.04.
I introduced it during last days after reading this post 
http://www.mail-archive.com/[email protected]/msg36825.html 
and other similar forum discussion, trying to fix the suspend feature, without 
success. 

Thank you for support
Salvatore
