Not sure if anyone can help as I think it might be a a fault with the hardware.
However it may be something else so I will ask
I have an acer travelmate 4230, Dual core 1.6GHz, 1GB,Running Vista Home Premium.
The other day my touchpad just stopped working, I have to use an external mouse which is quite annoying when travelling.
The drivers seem in order and says the device is working properly.
