Claims11
An anti-theft device for a computer system, comprising:
- a lock, configured to confine the computer system within an area;
- a slot, formed on a housing of the computer system for fixing the lock;
- and
- a switching module, for cutting off power supply for a plurality of external interfaces of the computer system when the lock is fixed to the slot, wherein a pulse signal, a magnetic signal or an infrared interdiction signal is generated for the switching module to cut off power supply;
- wherein the plurality of external interfaces are selected from a universal series bus (USB), an RJ45, a wireless network interface card, an IEEE 1394 and an External Serial Advanced Technology Attachment (E-SATA).
