Claims20
A computer, comprising:
- a first case and a second case that removably mate together to form an enclosure;
- a shaft attached to the first case;
- a hook rotatably coupled to the shaft and having an open position and a latched position, the hook including a first side and a second side;
- wherein the first side of the hook is engaged with a hole formed in a side wall of the second case when the hook is in the latched position and the first and second cases are mated, and where the first side of the hook is disengaged from the hole when the hook is in the open position;
- the second side of the hook is formed of a ferrous material and located adjacent to a side wall of the first case, wherein the hook rotates to the open position responsive to a magnet being positioned on an outside of the side wall of the first case, near the second side of the hook;
- and
- a coil spring coupled to the shaft and forcing the hook towards the latched position.

A method of manufacturing a computer, comprising
- forming a first case with a side wall fabricated from a non-ferrous material;
- forming a second case with a side wall fabricated from a non-ferrous material, wherein the first case and the second case removably mate together to form an enclosure;
- attaching a latch to the first case, where the latch comprises:
- a shaft attached to the first case, and
- a hook rotatably attached to the shaft, where the hook is rotatable between an open position and a latched position, the hook having a first side and a second side;
- wherein the first side of the hook is engaged with a hole formed in the side wall of the second case when the hook is in the latched position and the first and second cases are mated, and where the first side of the hook is disengaged from the hole when the hook is in the open position;
- and
- the second side of the hook formed of a ferrous material and located adjacent to the side wall of the first case, wherein the hook rotates to the open position responsive to a magnet positioned on an outside of the side wall of the first case, near the second side of the hook;
- and
- attaching a coil spring to the shaft that forces the hook towards the latched position.
