Computing device security cable

A system comprising:

• a computing device;
• and
• a security cable comprising a lock unit attached to a restraining cable;
• the lock unit configured to removably fasten to the computing device,
• the lock unit further configured to switch the security cable between a first configuration, a second configuration, and a third configuration based on wireless communication with a security cable key,
• wherein, in the first configuration, the lock unit is fastened to the computing device and a first instruction is transmitted from an electronic circuit of the lock unit to a processor of the computing device that places the computing device in an inactive state,
• wherein, in the second configuration, the lock unit is removable from the computing device and a second instruction is transmitted from the electronic circuit of the lock unit to the processor of the computing device that places the computing device in an active state,
• wherein, in the third configuration, the lock unit is removable from the computing device and the computing device remains in the inactive state,
• wherein the security cable further comprises a first electronic coupling, and the security cable is configured to supply operating power to the computing device through the first electronic coupling, and
• wherein the first electronic coupling is configured to transmit a data signal to a processor of the computing device through a second coupling, wherein the data signal includes identification information of the security cable.

A security cable comprising:

• a restraining cable;
• a lock unit attached to the restraining cable,
• the lock unit having a key interface, wherein the security cable switches between a first configuration, a second configuration, and a third configuration in response to wireless communication between a security cable key and the key interface,
• the lock unit comprising a set of retractable tabs, the set of retractable tabs configured to removably fasten the lock unit to a computing device,
• wherein, in the first configuration, the set of retractable tabs is in a protruded position, resulting in the lock unit being fastened to the computing device and the computing device being tethered to a stationary object,
• wherein, in the first configuration, the lock unit places the computing device in an inactive state by transmitting a first instruction from an electronic circuit of the lock unit to a processor of the computing device,
• wherein, in the second configuration, the lock unit is removable from the computing device and a second instruction is transmitted from the electronic circuit of the lock unit to the processor of the computing device that places the computing device in an active state,
• wherein, in the third configuration, the lock unit is removable from the computing device and the computing device remains in the inactive state,
• wherein the security cable further comprises a first electronic coupling, and wherein the security cable is configured to supply operating power to the computing device through the first electronic coupling, and
• wherein the first electronic coupling is configured to transmit a data signal to the processor of the computing device through a second coupling, wherein the data signal includes identification information of the security cable.
