A friend of mine recently upgraded her laptop to windows 7, but then she found that the "on/off" button of the touchpad doesn't work anymore. Therefor, she asked me for help. As I don't know the model of her laptop, I downloaded the driver on sysnaptics' web site, which is supposed to work for any kind of touchpad.
However, although we can turn of the laptop by software method after installation of the driver, the "on/off" button still doesn't work.
I feel that it's a bit strange. Is the button not part of the touchpad so Synaptics' driver doesn't need to support it???
