A lock is designed to prevent theft of a notebook computer and is formed of a housing, a metal fastening, a locking mechanism, and a retaining mechanism. The locking mechanism includes an arresting bolt with a conical tip and a dial block. The retaining mechanism includes a retaining bolt with an inclined surface, which is pushed by the conical tip of the arresting bolt such that a hooked end of the retaining bolt is engaged with a T-shaped slot of the notebook computer at such time when the wheels of the locking mechanism are turned randomly. When the wheels of the locking mechanism are turned to a set series of numbers, the conical tip of the arresting bolt moves away from the inclined surface of the retaining bolt, thereby resulting in disengagement of the hooked end of the retaining bolt with the T-shaped slot of the notebook computer.

The reseat system according to claim 2, wherein either one of the first and the second reseat components is a conical shape having larger outer diameter on an end remote from the stylus than on an end adjacent to the stylus and the other reseat component is a pair of balls. 4. The reseat system according to claim 2, wherein either one of the first and second reseat components is a cylinder having predetermined inclination in an axial direction greater than zero sufficient to oppose resaet shift and the other is a pair of balls. 5. The reseat system according to claim 2, wherein either one of the first and the second reseat components is a conical shape having larger outer diameter on an end remote from the stylus than an end adjacent to the stylus and the other reseat component is a pair of cylinders arranged in V-shape. 6.
