This is for a VGN-NR330E running Vista. The AV Mode button no longer works. Pressing AV Mode when the laptop is off simply boots Windows. I downloaded and ran the Vaio Launcher Update, but this did not solve the problem.
You may download and reinstall the VAIO® AV Mode Launcher on Sony support page or by using Vaio Care application. Unfortunately, your Vaio VGNTZ17GN is a non-U.S. model. We do not have the compatible software for your computer.
