Abstract: 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.

Abstract: Disclosed is a media console of a personal computer system that includes a drive housing that can be moved within a base member between an open position and a closed position. A direct access storage device (e.g., floppy disk drive) is disposed within the drive housing and has an opening for receiving a removable storage medium. The open position is characterized in that the opening in the direct access storage device is accessible to a user while the closed position is characterized in that the opening in the direct access storage device is not accessible to the user. The drive housing pivots on pins which are disposed at opposite ends of a back portion of the drive housing. The pins fit within grooves which are located at each end of the base member. A spring coupled to the base member and the drive housing biases the drive housing toward the open position. A latch for latching the drive housing in the closed position is coupled to the base member and the drive housing. Pressing on the top of the drive housing unlatches the latch and allows the drive housing to move from the closed position to the open position.

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.
