Patent ID: 7646110

Claim:
An apparatus, comprising: an alternating current (AC) mains voltage monitor to continuously monitor AC mains voltage during operation and to issue an interrupt where the AC mains voltage drops below a threshold more than a predetermined number of times; and, a controller to receive the interrupt and in response to cause one or more components of an electronic device to reduce power usage from the AC mains to compensate for the AC mains voltage dropping below the threshold more than the predetermined number of times, by turning off one or more of the components of the electronic device in response to receiving the interrupt, wherein the controller is further to receive one or more of sampled AC mains voltage, sampled AC mains current, and sampled AC mains power to manage power usage by the components of the electronic device based on the sampled AC mains voltage, the sampled AC mains current, and/or the sampled AC mains power, wherein the controller is to receive the sampled AC mains voltage, the sampled AC mains current, and/or the sampled AC mains power a predetermined number of times per second and not continuousy, and wherein the controller is further to manage power usage in response to receiving one or more of the sampled AC mains voltage, the sampled AC mains current, and the sampled AC mains power by increasing and/or reducing power usage by, but not turning off, one or more of the components of the electronic device.
