Abstract
A computer system includes: a host unit, a power management system, a data backup power supply, a switching mode power supply, an auxiliary storage unit and a memory. The power management system generates a hibernation signal when an event is not generated from peripheral devices for a predetermined time period, a battery driving signal is output from the data backup power supply due to a power-off operation, or a command word is generated in accordance with performing a scheduled program. The host unit backs up the current operational environment and data in the auxiliary memory storage unit according to the hibernation signal, and outputs a powerdown command word so that the power management system interrupts the system power supply by outputting a main power cut-off signal or outputting a battery power cut-off signal according to the powerdown command word. The power management system resumes the power supply by outputting a power supply signal when a WAKE-UP signal in generated while the power is interrupted. When power is resumed, the host unit retrieves the backed up data and the work environment, identifies the source outputting the WAKE-UP signal, and then performs the corresponding operation.
