SYSTEMS, METHODS AND DEVICES FOR STANDBY POWER SAVINGS
First Claim
1. A system for managing maintenance activities on system on a chip (SoC) comprising:
- a processor configured to;
restrict maintenance activities from occurring during the low-power state when not in a maintenance window;
determine to send a notification of the maintenance window;
generate a maintenance window notification; and
when a maintenance action occurs during the maintenance window,transition the computing system to an active state; and
perform the maintenance action.

Abstract
A power delivery system of a computing system that is on alternating current (AC) power limits software administrative tasks to a system-controlled and tunable broadcast window. This window limitation allows a computing system to enter and stay in low-power states without variable disturbances from administrative functions that can be relegated to the window. For example, maintenance is restricted until the computing system broadcasts a notification. Legacy software and devices that do not understand these notifications can be told the AC power is not present nominally, and then be notified of AC power presence during maintenance intervals.

9. An apparatus of a computing system configured to provide a maintenance window, the apparatus comprising:
a processor configured to; select a maintenance window for maintenance activities of the computing system; detect an idle state of the computing system outside of a maintenance window; transition devices of the computing system to a low-power device state; transition a central processing unit of the computing system to a low-power C state; transition the computing system to a low-power platform state; restrict maintenance activities from occurring until within a maintenance window; register one or more systems for notification of a maintenance window through an application programming interface (API); and notify the one or more systems of the maintenance window. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A computer program product comprising a computer-readable storage medium that stores instructions for execution by a processor to perform power management operations of a system on a chip (SoC), the operations, when executed by the processor, to perform a method, the method comprising:
-
transitioning the SoC to a low-power state; restricting maintenance activities from occurring during the low-power state when not in a maintenance window; determining to send a notification of the maintenance window; generate a maintenance window notification; and when a maintenance action occurs during the maintenance window, transitioning the SoC to an active state; and performing the maintenance action. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
