Patent Number Title Of Patent Date Issued
5630142 Multifunction power switch and feedback led for suspend systems May 13, 1997
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
5603038 Automatic restoration of user options after power loss February 11, 1997
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
5581692 Automatic clearing of power supply fault condition in suspend system December 3, 1996
A computer system having a CPU, a switch, a power supply, and power supply control logic for controlling the state of the power supply via a control signal. The power supply control logic comprises circuitry to interface control of the power supply between the CPU and the user via the sw
5577220 Method for saving and restoring the state of a CPU executing code in protected mode including es November 19, 1996
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
5560023 Automatic backup system for advanced power management September 24, 1996
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 b
5551043 Standby checkpoint to prevent data loss August 27, 1996
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
5548763 Desk top computer system having multi-level power management August 20, 1996
A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off 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 op
5530879 Computer system having power management processor for switching power supply from one state to a June 25, 1996
A computer system having a CPU, a power management processor, a switch, a modem, a timer, an override circuit, a glitch circuit, and a power supply in circuit communication. The power supply has several power supply states, which are controlled by the power management processor responsiv
5513359 Desktop computer having a single-switch suspend/resume function April 30, 1996
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
5511204 Performing system tasks at power-off using system management interrupt April 23, 1996
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
5511202 Desktop computer system having zero-volt system suspend and control unit for ascertaining interr April 23, 1996
A desktop computer system having the capability to suspend and resume the state of the computer system. The suspended system state is saved to the system hard file such that system power may be removed, effectively allowing a system suspend requiring no power from the power supply.
5497494 Method for saving and restoring the state of a CPU executing code in protected mode March 5, 1996
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
5134580 Computer with capability to automatically initialize in a first operating system of choice and r July 28, 1992
A computer system with read-only memory and permanent read/write memory provides the user with the capability of loading an alternate operating system at the conclusion of a session without turning the computer off and then on. A customization word with a system request (SR) bit is locat
