Patent ID: 7213140

Claim:
A method for enabling a computer to self-start comprising: selecting a predetermined time for self-start when the computer is on; adjusting an alarm setting stored in a memory of an RTC/NVRAM chip (Real-time Clock/Non-Volatile RAM memory chip) according to the predetermined time; enabling the System Control Interrupt (SCI) bit in a Southbridge chipset of the computer; wherein the Southbridge chipset responds to a matching signal sent from the RTC/NVRAM chip when the computer is off; powering the computer off; and enabling the Southbridge chipset for providing electrical power with a power supply if a clock value of the RTC/NVRAM chip matches the alarm setting by: sending a power on signal to the power supply via a power supply connector on a motherboard of the computer; powering voltages of pins of the power supply connecter to appropriate levels; checking if the voltages in the pins of the power supply connector are stable; sending a power good signal from the power supply to a processor of the computer; and starting the computer upon receiving the power good signal.
