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： 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.

摘要： A computer system comprising an input/output device, a processor, a memory device, and a bridge logic device for interfacing the memory device to the processor and input/output device incorporates a refresh logic device for generating a memory refresh signal during suspend mode. Because the rate at which memory must be refreshed generally depends on the temperature of the memory device, the refresh logic varies the frequency of the refresh signal according to the temperature of the memory device, resulting in substantial power savings. In a preferred embodiment, the refresh logic uses a normal-rate refresh signal at the beginning of suspend mode and incrementally steps down the refresh rate as the memory temperature decreases. In other embodiments, the refresh logic incorporates a signal generator which produces a refresh signal at a frequency that varies according the output voltage from a temperature sensor or the temperature-sensitive resistance of a thermistor. In yet another embodiment, a variable-rate refresh logic is incorporated into the memory device, resulting in a self-refreshing memory module.

摘要： A portable computer is provided with comparable performance to a desktop computer when docked at a docking station. When the portable computer is docked or physically coupled to the docking station, the microprocessor of the portable computer switches to an increased operating frequency. The onboard power supply of the portable computer is also disabled on docking, and the portable computer receives power from the docking station. Increased heat transfer capability is also enabled in the portable computer when it is docked, providing increased cooling to the portable computer. The portable computer thus overcomes the normal performance disparity between a portable computer system and a desktop computer system when the portable computer is docked.

摘要： A method and apparatus for increasing system functionality through a predefined interface is disclosed. Signal lines which are not used or which are not used in certain modes are connected to an interconnection device instead of being connected to an interface wherein the output of the interconnection device is connected to the interface where such lines would have been connected. The interconnection device also has a set of inputs for receiving signals from a device providing the desired functionality. A controller chooses between the two sets of inputs to control what signal lines are connected to the predefined interface. Accordingly, during certain modes of operation, the added functionality from a device whose output is being switched into the interface can be supported. In one embodiment, speaker phone capability is provided for even though the predefined PCMCIA interface does not support such capability. The disclosed design continues to maintain capability with all systems adapted to be used with such predefined interface.

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 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.
