Power management of computing and communications systems during power fluctuation and sudden power failure events

A method of graceful power transitions for a computing system comprising the following steps:

• configuring and deploying a computing system, comprising:
• a processor,
• memory configured to communicate with the processor,
• non-volatile memory containing operating system and other software, configured to communicate with the memory,
• a network interface configured to communicate with the processor, the network interface configured with a first wireless communications equipment,
• input/output channels configured to communicate with the processor,
• a power control system,
• a modular battery,
• power sense circuitry, the power sense circuitry further configured to connect and communicate through a second wireless communications equipment, and
• the computing system further configured to connect to and be powered by an external power source, the power sense circuitry configured to detect when the external power source has a power loss and further configured to provide a notification of the power loss to the power control system by sending a message wirelessly from the second wireless communications equipment to the first wireless communications equipment of the computing system, thereby allowing the power sense circuitry to be located away from the computing system, and the power control system configured to switch to relying on modular battery power to power the computing system upon receiving a notification of power loss;
• sensing, by the power sense circuitry, when the external power source has a power loss,
• notifying, the power control circuitry, by the power sense circuitry, that a power loss has occurred,
• switching the computing system to rely on modular battery power, and
• waiting, by the computing system, for a pre-configured wait time before initiating a graceful hibernation sequence of the computing system, thereby keeping computing system power constant for a power fluctuation event.
