Description
Technical field
The invention belongs to the Computer Applied Technology field, relate in particular to a kind of method and device of realizing the computing machine quick turn-on.
Background technology
Huge day by day along with operation system of computer, the start-up time of system is more and more longer, although the developing by leaps and bounds of computer technology makes computer processing speed and computing velocity more and more faster, but because therefore Computer Processing speed and computing velocity make increase day by day along with the continuous huge of system the start-up time of computing machine to shortening the not significantly effect of system start-up time.
In the present invention, relate to following several computing machines state of living in, be respectively:
The S0 state, under this state, computing machine is in the normal boot-strap state;
The S3 state, under this state, computing machine is in the dormant state that suspends to internal memory, and each field data that computing machine will enter the computing machine before the dormant state is kept in the internal memory, the interior boosting voltage 5VSB power supply maintenance work down that has+5 volts, other hardware then is in closed condition; When triggering S3 dormancy awakening incident, then computing machine reads and carries out each field data of preservation from internal memory, enters S3 dormancy state before thereby computing machine is returned to;
The S4 state, under this state, computing machine is in the dormant state that suspends to hard disk, each field data that computing machine will enter the computing machine before the S4 dormancy is kept in the hard disk, each hardware in the computing machine is in closed condition, when for example pressing power switch and trigger the S4 wake events, computing machine writes original position by each preceding field data former state of the S4 state that enters that operating system or Basic Input or Output System (BIOS) (BIOS) will be kept in the hard disk, thereby reaches the dormant state self-consistentency;
The S5 state, under this state, computing machine is in the normal shutdown state, and external communication electricity AC is still to computer power supply;
The G3 state, under this state, the external communication of computing machine electricity AC power down has only the powered battery on the computer motherboard.
Think that in order to shorten the system start-up time user provides start fast to experience, and in the prior art, adopts following dual mode to realize quick turn-on:
Mode 1: the default action of " shutdown " button of computer electric power management system is set to " standby ", thereby, when the user shuts down, system will enter holding state S3, computing machine suspends to internal memory, when system enters this S3 state, all information that computing machine is entered before the S3 dormancy are kept in the internal memory, wherein, be kept at all computer field information such as value that these all information in the internal memory comprise central processing unit (CPU) information, operation system information, application information, each hardware information and related register; Under this S3 state, each hardware in the computing machine all is in closed condition, has only internal memory still constantly to refresh to guarantee to preserve in the internal storage location integrality of content under+5 volts boosting voltage 5VSB power supply.When computing machine was in start S0 state and normal shutdown S5 state, computer power supply connected alternating current, and 5VSB all exists as boosting voltage.
