Abstract: A computer system includes a processor and a non-volatile memory device coupled to the processor. The processor either generates or receives a command to enter a low-power mode. The non-volatile memory device includes a first area reserved for random-access read/write cycles by the processor and a second area reserved for storing processor state information upon entering the low-power mode. The processor and the memory device both are configured to lose power during the low-power mode. In some embodiments, the memory device also serves as a read-only memory device and as a persistent storage device for data and application programs.

Abstract: A computer system that provides device specific power characterizations for power control and budgeting functions is disclosed. The device driver programs of the computer system or a power characterizer of the system determines device specific power characterizations for corresponding devices under device specific controlled conditions. The device specific power characterizations are stored in persistent storage for subsequent use by power control and budgeting functions.

Abstract: A computer system with system power consumption tracking and reporting is disclosed including a background task that determines a hardware configuration of the computer system and that detects new or novel hardware configurations. The background task updates data sets in the system power table that correspond to previously logged hardware configurations and creates new data sets in the system power table for the new or novel hardware configurations. The system power table logs indications of system power consumption for the corresponding hardware configurations as well as related information.
