    摘要: A method and apparatus for transitioning the CPU of a computer system to a lower performance level upon removal of AC power. Circuitry within the system input power control detects the removal of the AC power. The circuitry generates an event that causes power management software to immediately transition the CPU to a lower performance level sufficient to prevent the unwanted shutdown of the system. The AC power removal detection and CPU transition are effected while the system maintains an operational power level due to residual power in the system capacitors.

    摘要: A system including a component (e.g., a processor) with a clock and a thermal management controller that monitors a temperature in the system. The thermal management controller varies the component between different performance states (e.g., cycles the processor between a high and a low performance state) when an over-temperature condition is detected. The thermal management controller further throttles the clock of the component while in the low performance state until the over-temperature condition is removed.

    摘要: A novel method for upgrading a first program sequence in a computer system such that the computer system remains operable even if the upgrade process results in an incorrectly stored program sequence. The method uses the steps of storing the second program sequence in a second region of a memory, determining whether the second program sequence is stored correctly, and enabling the second program sequence if it is stored correctly. The first program sequence remains enabled if the second program sequence is not stored correctly.

    摘要: A computer typically includes a power switch. A method of power switch management of the computer may be implemented in which a system power operation of the computer is performed if the power switch has been activated in a first manner and an operation of the computer other than a system power operation of the computer is performed if the power switch has been activated in a second manner. The operation of the computer other than a system power operation of the computer can include, for example, a suspend/resume operation of the computer.

    摘要: Memory allocation for fast platform hibernation and resumption of computing systems. An embodiment of an apparatus includes logic at least partially implemented in hardware, the logic to: dynamically allocate at least a first portion of a nonvolatile memory; in response to a command to enter the apparatus into a standby state, the logic to store at least a portion of a context data from a volatile memory to the dynamically allocated first portion of the nonvolatile memory; and in response to a resumption of operation of the apparatus, the logic to copy at least the portion of the context data from the first portion of the nonvolatile memory to the volatile memory, and to reclaim the first portion of the nonvolatile memory for dynamic allocation.

    摘要: A method and apparatus for intelligent power management for low power link states. Some embodiments include methods, apparatuses, and systems for a device coupled to a controller via a link; a link power management engine to alter a power state of the link based on a transaction and some knowledge of future transactions between the device and the controller; and a memory or logic to store the link power management engine. In some embodiments, the memory stores information about at least one of the following: the power state of the link, the device buffering, the controller or device state or a history of transactions. In some embodiments, the device is a peripheral of a computer system. In some embodiments, the method may include transitioning the device to various link states. Other embodiments are described.
