DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 and 2, a computer security system of a preferred embodiment of the present invention includes a motherboard 12, a power supply 14, and a lock 16. The lock 16 is a mechanical keyed lock configured for use as a switch. The lock 16 includes a switch portion 160, and a key 161. The switch portion 160 includes a first terminal 162, and a second terminal 164. The first terminal 162 is electrically connected to the power supply 14 via an electrical wire 18. The second terminal 164 is electrically connected to an electrical source module 120 of the motherboard 12 via an electrical wire 19.

The lock 16 is chosen according to a certain value of voltage provided by the power supply 14. The lock 16 further includes a mechanical member (not shown) to control open/closed states of the switch portion 160. The key 161 is rotated to open or close a power supply circuit formed by the electrical wires 18, 19, the first terminal 162, and the second terminal 164. In the preferred embodiment, the lock 16 is mounted on a front panel of the computer for easily operation. The lock 16 may alternatively be mounted separately according to preference.

In use, before the user leaves a computer, the key 161 of the lock 16 is rotated to open the power supply circuit. Then input power of the motherboard 12 of the computer is shut off, thus providing another level of security beyond a password. When the user returns, the key 161 is used again for closing the power supply circuit. Therefore, the power supply 14 provides the power needed by the motherboard 12, and the computer works normally after other optional security steps are satisfied such as inputting a password of the computer thereafter.

It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being a preferred or exemplary embodiment.

Claims

1. A computer security system comprising: a motherboard of a computer;a power supply configured for providing power to the motherboard via a power supply circuit; anda lock electrically connected in series with the power supply circuit between the motherboard and the power supply to control power to the motherboard, the lock being configured for controlling open/closed states of the power supply circuit.

2. The computer security system as claimed in claim 1, wherein the lock is a mechanical keyed lock configured for use as a switch.

3. The computer security system as claimed in claim 2, wherein the lock further comprises a switch portion, the switch portion comprises a first terminal, and a second terminal; the first terminal and the second terminal are respectively connected to the motherboard and the power supply via the power supply circuit; a key controls open or closed states of the power supply circuit by opening or closing a connection between the first terminal and the second terminal.
