Hello mate, thanks for your response.
I had already installed the VAIO Event Service and it didn't work, however, I uninstalled and installed what you said above and it worked!! I guess that VAIO Event Service depends on VAIO Control Centre?? So my Volume display and brightness etc is all good
My scroll still doesn't work on my touchpad though, does yours? I've downoaded a pointing device driver from another model to produce no joy, but I'm yet to locate the driver externally without hitting spam-city. I remember the service was called APOINT.EXE by Alps.
I had also, already installed the latest 64-bit INTEL driver for 5100 Series directly from the Intel Website, but that didn't fix it, Again, I uninstalled and re-installed and my first speedtest seems good! Perhaps the 32-bit version doesn't get auto-uninstalled and interferes with the 64-bit version??
Anyways all is good mate, thanks very much for your help, appreciated
