Look at the Function keys (F1 - F12) on your keyboard, if any of those keys have an icon that looks like a touchpad with a line through it, try pressing that key or Fn + that key to test if that gets the touchpad working with a visible cursor.
If not, disconnect any USB devices connected to your laptop to test if that resolves the problem.
If not, connect an external mouse to your laptop, do you then see a cursor on your screen?
