ABSTRACT:
This is a system and method of intelligently terminating power to a computing device. The system may comprise: a processing device; a power source connected to the processing device; a switch connected to the power source; and a control system run by the processing device and connected to the power source and the switch. In addition, the system may include a deadman timer which provides a fail-safe operation. Further, the system may include a method and apparatus for executing an orderly shut down procedure for software and hardware. Moreover, the system could be tied to a thermal and/or power management system. Additionally, the system could initiate an orderly shut down of peripheral devices connected to the system serially or by parallel connections. Other devices, systems and methods are also described.
