Is it possible to scroll using your touchpad on this laptop? All my older laptops let you scroll in some way but I must be missing something on my Fujitsu.
Check whether the touchpad drivers are installed correctly and if necessary update them. Depending on the kind (and age) of your touchpad you might not be able to do a two-finger scroll but scrolling by using the edge of the touchpad should be possible.
You can grab the drivers here:
Further to Ke Gu - it is probably only the edges of the pad used for scrolling. This from the AH531 user manual:
Scrolling Up/Down: To scroll up or down, place your finger on the right side of the pad and move it forward or backward to scroll up or down. Scrolling Right/Left: To scroll right or left, place your finger on the bottom of the pad and move it right or left to scroll right or left.
It took me a while to work it out for my Sony! There are also other gestures described for continuous scrolling.
