Can anyone help me how to move whole base as shown in 1st basic tutorial using laptop touchpad..!!

I suppose that your problem is that you don’t have a scroll-wheel since you’re using a touchpad…

You need to go to “File” > “User preferences” > go to the “Input” tab and on the left you can check the “emulate 3 button mouse” checkbox.

Once you’ve done that, each time you press Alt+LBM, blender will consider it as being a scroll-wheel clic. 😉

Don’t forget to save your Blender User Preferences at the bottom-left of the window.
