Like most modern laptops, IBM/Lenovo laptops feature a built-in touchpad that you can use as a substitute for an external mouse device. If you experience a non-functional or "locked" touchpad, then you have one of two possible problems; either the touchpad's drivers are corrupt or a user has manually locked the touchpad. In either case, you can unlock your touchpad and restore it to functionality quickly.
