1. 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.

7. An electronic device comprising:
-
one or more components, each component using power originating from an alternating current (AC) mains; and
,a power-monitoring sub-assembly to continuously monitor AC mains voltage during operation, to issue an interrupt where the AC mains voltage drops below a threshold more than a predetermined number of times, and to cause one or more of the components 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, wherein the power-monitoring sub-assembly comprises; an AC mains voltage monitor to continuously monitor the AC mains voltage and to issue the interrupt where the AC mains voltage drops below the threshold more than the predetermined number of times; and
,a controller to receive the interrupt and in response to cause one or more of the components 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 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, by increasing and/or reducing power usage by, but not turning off, one or more of the components, the controller receiving 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 continuously. - View Dependent Claims (8, 9, 10, 11)

12. A method comprising:
-
sampling one or more of alternating current (AC) mains voltage, AC mains current, and AC mains power a predetermined number of times per second, and not continuously; until an interrupt corresponding to the AC mains voltage as continuously monitored during operation dropping below a threshold more than a predetermined of times, managing power usage from the AC mains by one or more components of an electronic device based on the AC mains voltage, the AC mains current, and/or the AC mains power as sampled, by increasing and/or reducing power usage by, but not turning off, one or more of the components; and
,in response to receiving the interrupt, causing one or more of the components of 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. - View Dependent Claims (13)
