I have a toshiba a305... and no it doesn't have an easy off button, it's a little bit older lappy, only 2GB ram and an intel core 2 duo... I just did a fresh install of windows 7 home premium and did the anytime upgrade to ultimate from the RC... in the RC I had it disabled but it showed up in the hidden icons area, so it was easy to disable. now it's nowhere to be found and the software won't install
Might be a stupid question to shoot out, but did you download the drivers from the site? Maybe it would reinstall the drivers and software so you can safely disable it?
