Method for suspending, resuming, and turning on a computer system without being affected by an abnormal power failure

A method for resuming a computer system without being affected by a power failure, the method comprising the steps of:

• receiving a wake up instruction, which comprises a resuming instruction or a turn-on instruction;
• determining a current state of the computer system;
• performing a normal turn-on procedure to enter the computer system into a normal operation state if the current state of the computer system is neither in a suspend to RAM (STR) sleep state nor in a suspend to disk (STD) sleep state;
• performing an STD resuming procedure by restoring relevant operating information and context of related devices from a hard disk to the computer system so that the computer system enters into a normal operation state if the computer system is in the STD sleep state;
• determining if a power failure happened when the computer system was in the STR sleep state;
• performing the STD resuming procedure by restoring the relevant operating information and context of related devices from the hard disk to the computer system so that the computer system enters into a normal operation state if the computer system is in the STR sleep state and an abnormal power failure had occurred;
• and
• performing an STR resuming procedure by restoring the relevant operating information and context of related devices from a memory to the computer system so that the computer system enters into a normal operation state if the computer system is in the STR sleep state and no power failure had occurred.

A method for suspending a computer system without being affected by a power failure, the method comprising the steps of:

• receiving an instruction, wherein the instruction is selected from either one of a suspend to RAM (STR) instruction and a suspend to disk (STD) instruction;
• saving relevant operating information and context of related devices into a memory in the computer system;
• saving relevant operating information and context of related devices into a hard disk in the computer system;
• determining the instruction category;
• entering the computer system into an STR sleep state if the instruction received is the STR instruction;
• and
• entering the computer system into an STD sleep state if the instruction received is the STD instruction.

A method for turning on a computer system without being affected by a power failure, the method comprising the steps of:

• receiving a wake-up instruction, which comprises a resuming instruction or a turn-on instruction;
• determining if a power failure happened to the computer system;
• activating a “wake on LAN” function and a “ring in wake up” function if a power failure happened to the computer system;
• determining a current state of the computer system;
• changing the current state of the computer system into a suspend to disk (STD) sleep state if the computer system is in a suspend to RAM (STR) sleep state and a power failure had happened to the computer system;
• entering the computer system into the STD sleep state;
• entering the computer system into the STD sleep state if the computer system is in the STD sleep state and a power failure had happened to the computer system;
• entering the computer system into a soft-off sleep state if the computer system is neither in the STR sleep state nor in the STD sleep state and a power failure had happened to the computer system;
• determining a current state of the computer system if no power failure had happened to computer system;
• performing an STR resuming procedure if the computer system is in the STR sleep state and no power failure happened to computer system;
• performing an STD resuming procedure if the computer system is in the STD sleep state and no power failure happened to computer system;
• and
• performing a normal turn-on procedure if the computer system is in the soft-off sleep state and no power failure happened to computer system.
