摘要： A computer system that selectively disables power to wake on LAN (WOL) devices in the absence of AC power. In one embodiment, the computer system comprises a power supply and a power management controller. The power supply is configured to provide power to a wakeup device. The power management controller receives an AC voltage sense signal that indicates the presence or absence of an AC power source and enables the power supply to provide power to the wakeup device when the AC voltage sense signal is asserted. The power management controller preferably disables the power supply when the AC voltage sense signal is de-asserted. The computer system may operate in several states including an off state, a power on self test (POST) state, a working state, a trap state, and an armed state.

摘要： A battery powered computer system determines when the system is not in use by monitoring various events associated with the operation of the system. The system preferably monitors the number of cache read misses and write operations, i.e., the cache hit rate, and reduces the system clock frequency when the cache hit rate rises above a certain level. When the cache hit rate is above a certain level, then it can be assumed that the processor is executing a tight loop, such as when the processor is waiting for a key to be pressed and then the frequency can be reduced without affecting system performance. Alternatively, the apparatus monitors the occurrence of memory page misses, I/O write cycles or other events to determine the level of activity of the computer system.

摘要： A computer system supports operation of a CPU at multiple clock speeds. Logic in the computer system predicts the performance requirements of the CPU, and selects the fastest clock speed to optimize performance. In one embodiment, a Keyboard controller receives user inputs from various user input devices, including a mouse and keyboard. The Keyboard controller identifies user inputs that reflect a system command, such as, for example, a mouse click, selection of the Alt key with another key, or any special function keys associated with a software application. If such a user input is detected, the Keyboard controller generates a system management interrupt (SMI) to the CPU. In response, the CPU calls a speed control algorithm that identifies the source of the SMI and increases the clock speed to the processor by providing a control input to a multiplexer or switch that selects the highest clock speed for the CPU.

摘要： A computer system supports a fast hibernation operation to save power, while minimizing the amount of time it takes to enter the hibernation mode, and to resume normal operations. The system periodically stores data from system memory to non-volatile memory, such as a hard disk drive, during normal operations when the system is idle. The system includes activity monitors that detect when the data in memory pages is changed. The system periodically sweeps the monitors, and performs save operations to the non-volatile memory. When the system enters hibernation mode, the system determines which memory pages have been changed since the last save operation, and then saves those pages to memory. As an alternative, the system immediately can enter hibernation by supplying power to the memory pages that have not been saved since the last save operation. To implement this, independent switches under the control of the CPU of memory controller selectively turn off power to unsaved memory pages. The system can also implement a fast resume procedure by restoring the memory pages that have the highest priority, and saving the other pages in the background, or as need by the system devices. Prior to entering the hibernation mode, the pages may be prioritized based on various factors, including the last pages used, the pages used most frequently, or the pages that store the most critical data.

摘要： A computer system supports suspend operations to save power. The suspend operation maintains power to the system memory to enable a quick recovery from the suspend mode. To insure the accuracy of the data in system memory, a copy of the data is backed up to non-volatile memory, such as a hard disk drive, prior to entering the suspend mode. In addition, a signature value representing blocks or pages of memory also is saved with the data. When normal operation resumes, data in system memory is validated by calculating a new signature for each data block or page, and comparing it with the save signature values. If the signatures match, the data is assumed to be valid. If the values do not match, a restore operation proceeds to load the back up copy to that block of system memory. The algorithm may be run immediately upon resuming operation, or may run in the background when the CPU is idle. In the event a transaction occurs prior to validation of a particular memory location, the access is interrupted and the data is validated or restored. In addition, the error checking and restoration operations may be used during normal system operations to insure the integrity of data in the system memory or other volatile memory components.
摘要翻译：计算机系统支持暂停操作以节省电力。挂起操作维持系统内存的电源，以便能够从挂起模式快速恢复。为了确保系统内存中数据的准确性，在进入挂起模式之前，将数据副本备份到非易失性存储器（如硬盘驱动器）。另外，代表数据块或页面的签名值也与数据一起保存。恢复正常操作时，通过为每个数据块或页面计算新的签名，并将其与保存签名值进行比较来验证系统内存中的数据。如果签名匹配，则假定数据是有效的。如果值不匹配，则还原操作继续将备份副本加载到该系统内存块。该算法可以在恢复操作时立即运行，或者当CPU空闲时可以在后台运行。在特定存储器位置的验证之前发生事务的情况下，访问被中断并且数据被验证或恢复。此外，在正常系统操作期间可以使用错误检查和恢复操作以确保系统存储器或其他易失性存储器组件中的数据的完整性。

摘要： The invention is a method and apparatus for the thermal management of computers. The method features determining a temperature of a predetermined location in the computer, reading indirect inputs of the computer, determining desired states of cooling options based on the temperature and the indirect inputs, and placing the cooling options in their desired states. To determine the desired states of the cooling options, an index is formed based on the indirect inputs; and the index indicates to which of a plurality of tables of desired states of the cooling options to refer. Alternatively, the desired states of the cooling options are determined by adjusting the value of the temperature input based on the indirect inputs; the desired states of the cooling options also are dependent on the adjusted value of the measured temperature.
