I'm attempting to use a samsung np700z5b-s01ub laptop with Windows 7 64-bit but the touch pad is practically unusable. It's shear immense size causes it to be touched anytime I reach for it's keyboard. I plugged in an external keyboard for this post simply because it's so difficult to type anything on this laptop. I don't want to turn it off, but I really would love ot know why it works so badly and akwardly, is it multitouch? Do I need to download some other drivers for it?
