Abstract: 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 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. The suspend/resume/standby feature is implemented at a low cost using many standard components.

Abstract: 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.

Abstract: There is disclosed a display unit associated with a remote computer system communicating with a host computer system. Information, which is currently being displayed on the display unit and information to be displayed thereon are compared to determine any differences which exist therebetween. If the differences exceed a predetermined value, a update command is generated and transmitted by the host computer system to the remote computer system along with the information to be displayed if facilitate the updating of the display unit. If the differences do not exceed the predetermined value, it is determined which of a plurality change categories should be used to transmit the differences to the remote system in the most efficient manner. An update command, which is associated with the selected one of the plurality of change categories, and data representing the differences are then enqueued for transmission to the remote system to facilitate the updating of the display unit.
