摘要： A computer system having a CPU, a non-volatile storage device, a power management processor having a volatile power management configuration, and a power supply in circuit communication. Responsive to the AC power to the power supply being interrupted, the CPU restores the volatile power management configuration to said power management processor. The power management configuration comprises a value corresponding to a wake alarm and whether the power management processor responds to external events.

摘要： A computer system having a CPU, a non-volatile storage device, a power management processor having a volatile power management configuration, and a power supply in circuit communication. The power management processor controls the regulation of power to the CPU by the power supply. Prior to causing the power supply to cease providing regulated power to the CPU, the power management processor interrupts the CPU via a system management interrupt. Responsive to being interrupted via the system management interrupt, the CPU performs tasks associated with the power supply imminently ceasing to provide regulated power to the CPU. Such tasks include writing data to non-volatile memory and refreshing an alarm value in the power management processor. The CPU can extend the period of time before the power management processor causes the power supply to cease providing regulated power to the CPU while the CPU performs the necessary tasks.

摘要： A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off state. A control unit controls transitions between the various states. The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system. The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive. Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems. A single switch causes transitions between the various states. A visual feedback device, such as an LED is used to indicate the state of the computer system. While no power management driver is active, the control unit delays state transitions until a suitable power management driver is active.
摘要翻译：具有四种电源管理状态的计算机系统：正常操作状态，待机状态，暂停状态和关闭状态。控制单元控制各种状态之间的转换。待机状态的特征在于诸如视频控制器和硬盘驱动器之类的设备被置于对操作系统透明的低功率模式以及在计算机系统上执行的应用。暂停状态的特征在于执行代码被中断，并且将计算机系统的状态保存到硬盘驱动器上的文件，使得在将计算机系统的状态保存到硬盘驱动器之后可以去除系统电源。之后，在恢复系统电源之后，通过从硬盘驱动器读取并以不影响操作系统和应用程序的方式加载计算机系统的状态来恢复。正常操作状态和关闭状态对应于更传统的计算机系统的典型开启和关闭状态。单个开关导致各种状态之间的转换。诸如LED的视觉反馈装置用于指示计算机系统的状态。当没有电源管理驱动程序激活时，控制单元延迟状态转换，直到合适的电源管理驱动程序处于活动状态。

摘要： A computer system having at least three states of power management: a normal operating state, a standby state, and a suspend state. The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system. The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive. Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. As the standby state is entered, the state of the computer system is saved to a file on the hard drive in such a manner that if system power is accidently removed after the state of the computer system is saved to the hard drive, then the state of the computer system can be resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. The data saved as the system enters the standby state is invalidated if the system meets certain conditions.

摘要： A computer system having a suspend/resume capability in addition to the normal operating state and the off state. Closure events of single momentary pushbutton switch control changes between the normal operating state, the suspend state, and the off state, depending on the value of a flag. If the flag is set in a certain state, closure events of the switch cause the computer system to change back and forth between the normal operating state and the off state. If the flag is set in a different state, closure events of the switch cause the computer system to change back and forth between the normal operating state and the suspend state. The switch also controls the video subsystem of the computer system such that pressing the switch blanks the video display terminal giving the user instantaneous feedback of the switch press.

摘要： A method of saving and restoring the state of a CPU operating code in protected mode on a computer system. The save method makes use of BIOS operating in shadow RAM located in a region where linear addresses equal physical addresses while saving the state of the CPU. The registers that cannot be directly saved to memory are determined by searching the system memory for data structures that correspond to the particular register. The restore method uses dummy page tables that point to the shadowed BIOS to allow the CPU to reenter protected mode without generating a protection fault.
摘要翻译：一种在计算机系统上保存和恢复处于受保护模式的CPU操作代码的状态的方法。保存方法利用位于线性地址等于物理地址的区域中的影子RAM中的BIOS，同时保存CPU的状态。通过在系统存储器中搜索与特定寄存器对应的数据结构来确定不能直接保存到存储器的寄存器。恢复方法使用虚拟页表，指向受影像的BIOS，以允许CPU重新进入保护模式而不产生保护故障。

摘要： A suspend/resume computer system having a CPU, a non-volatile storage device, volatile registers and memory data, a power management processor, a backup suspend timer and a power supply in circuit communication. The power management processor controls the regulation of power to the CPU by the power supply. The suspend/resume system is controlled by an operating system having power management control. The backup suspend timer executes independently of the power management portion of the operating system. The backup suspend timer causes the system to suspend if the power management portion of the operating system ceases functioning and the system should otherwise be suspended.
