Go to the Sony web site and check service and support. Most computer company web sites will have downloads for factory installed software, drivers and applications.
I bought a used VAIO laptop with a great bundle of software. However, the jog dial and hot keys do not work. The software for both is not on the hard drive. Sony only provides system recovery disks, which erase everything on the hard drive. I'm looking for the software (applications, drivers, etc.) that would enable the hot keys and the jog dial. Can anyone help me in where to look and what I need to have in order to get these working?
