Digital computer and functional module for safeguarding data against access by unauthorized persons

摘要

The laptop computer has a screen part (101) and a keyboard stage (103) that are hinged together. The cursor control mouse pad (110) normally locates in a docking station (107) and is used there. It may also be removed and can be used away from the laptop using a Bluetooth link. In one variation the pad may be inserted with the keys accessible on the outer surface of the laptop.
