Before the explanation of carrying out embodiments of the invention, brief account several notions relevant at first with the embodiment of the invention.
Computer system has two kinds of mode of operations usually, and a kind of is normal mode of operation, and a kind of is non-normal mode of operation, and wherein, the non-normal working pattern comprises screen protection pattern and sleep pattern again.
The several modes of the definition of ACPI (Advanced Configuration and Power Interface, the ACPI) power management through computing machine is explained the implication of normal mode of operation and non-normal working pattern below:
The S0 pattern: all parts in the computing machine all are in the normal operation state, and at this moment, computer system is in normal mode of operation;
The S1 pattern: CPU quits work, and at this moment, except through the cpu clock controller CPU being closed, the miscellaneous part in the computing machine still is in the normal operation state;
The S2 pattern: CPU closes, and at this moment, CPU is in the state of decommissioning, and the cpu clock controller also is closed, but the miscellaneous part in the computing machine still is in the normal operation state;
The S3 pattern: the miscellaneous part except internal memory all is in the state of decommissioning, and is also referred to as STR (Suspend to RAM suspends to internal memory);
The S4 pattern: memory information writes hard disk, and all parts all are in the state of decommissioning, and is also referred to as STD (Suspend to Disk suspends to hard disk), and at this moment, system's primary power cuts out, but hard disk is still charged and can be waken up;
The S5 pattern: computing machine is in closed condition, all the parts Close Alls (comprising power supply) in the computing machine.
Computer system is called computer system when being in S1, S2, S3, S4 and S5 pattern and is in sleep pattern.
So-called screen protection pattern is a computer system when in official hour, not receiving any operation, on display, shows the pattern of multimedia messages such as picture stored or animation in advance.
Can find out that from foregoing description under S0 to the S5 pattern, the computer system power consumed reduces successively, and under the screen protection pattern, the power consumption of computer system is greater than the power consumption of computer system under the sleep pattern.
In addition; Because graphoscope shows the multimedia messages of storage in advance under the screen protection pattern; Graphoscope cuts out under S3, S4 and S5 pattern, so the computing machine security that is in those non-normal working patterns following times is greater than computing machine and is in the security under the normal mode of operation.
