Abstract
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.
