A computer device is disclosed comprising at least one component operable to process commands at command intervals, and control circuitry operable to set an idle mode timeout interval. The control circuitry stores a plurality of the command intervals, and then evaluates the command intervals to set the timeout interval by finding a qualifying number of the command intervals that fall within a sliding window. The component is configured into an idle mode if a most recent command interval exceeds the timeout interval. In this manner, after entering the idle mode the probability that the next command will be processed within the sliding window is reduced, thereby helping to optimize power consumption.

A server management apparatus for lowering migration costs during scale-in/scale-out and workload consolidation of a cluster system(s) to thereby reduce power consumption is disclosed. The apparatus manages a physical server group which renders operative a virtual server group thereon and, when putting into practice a cluster system including a plurality of virtual servers placed in the physical server group, manages the layout state of virtual servers pursuant to the load state of the virtual server group. When executing scale-in, a virtual server operating on a physical server with the minimum number of operative virtual servers is specified as a shutdown target. When executing scale-out, a workload variation is predicted to control a scale-out destination of cluster system so that load variation-resembled cluster systems gather on the same physical server. The scale-in execution timing is delayed if the predicted load variation tends to rise and accelerated if it falls.

Various embodiments of methods and systems for adaptive thermal management techniques implemented in a portable computing device (“PCD”) are disclosed. Notably, in many PCDs, temperature thresholds associated with various components in the PCD such as, but not limited to, die junction temperatures, package on package (“PoP”) memory temperatures and the “touch temperature” of the external surfaces of the device itself limits the extent to which the performance capabilities of the PCD can be exploited. It is an advantage of the various embodiments of methods and systems for adaptive thermal management that, when a temperature threshold is violated, the performance of the PCD is sacrificed only as much and for as long as necessary to clear the violation before authorizing the thermally aggressive processing component(s) to return to a maximum operating power.

A system for controlling battery usage in a mobile power supply includes a controller for monitoring a state of charge of the battery and the voltage and switching off all power from the battery when the battery reaches a predetermined power off state of charge or a low voltage condition. A switch provides power to the controller in response to receipt of power from an other source, thereby causing the controller to resume monitoring of the state of charge of the battery. When the battery reaches a predetermined power off state of charge, the controller switches off power from the battery. The switch turns the controller back on in response to receipt of power from the other source. When the battery is recharged to a predetermined restart state of charge and when the voltage reaches a restart voltage, power from the battery is switched back on.

The life of a secondary battery is extended and important data is backed up when power trouble, such as an incidental power failure, occurs. When a sudden power failure occurs, a battery supplies backup power to a memory for storing data to be backed up. By using a main switch for turning the main power supply of the apparatus on or off, the supply of the backup power from the battery to the memory is stopped, interlocked with the main switch, when the main switch shuts down the main power supply. This reduces the number charge-discharge cycles of the battery, prevents deterioration of the battery, and prolongs the life of the battery.
