In the computer mode conversion method of the embodiment of the invention and the device, preserve the power consumption when reducing computing machine and switching to standby through data that system recovery is needed through variety of way, but the time that simultaneous computer recovers is lower again.
The computer mode conversion method of the embodiment of the invention is used for a computing machine, and when said computing machine is in when suspending to internal memory STR state, the power consumption of said computing machine is first power consumption; When said computing machine from suspending to hard disk STD state exchange to open state, the consuming time of said computing machine is first amount consuming time, it is characterized in that, said computer mode conversion method is as shown in Figure 1, comprising:
Wherein, the power consumption that said computing machine is in said particular state is second power consumption, and said second power consumption is less than said first power consumption; It is second amount consuming time that said computing machine is transformed into the consuming time of said open state from said particular state, and said second amount consuming time is less than first amount consuming time.
The specific embodiment of the invention is through the order of response first power state transition; Make computing machine get into said particular state; At the power consumption of this particular state power consumption less than the S3 state, but its resume speed is more very fast than suspending to hard disk STD state again, has realized the balance of resume speed and power consumption.
In specific embodiment of the present invention, said particular state is different from ACPI (ACPI, Advanced Configuration and Power Interface) the defined any state of standard.
Certainly; System after open state is transformed into the particular state the application's specific embodiment, when the user need continue to use a computer, also need be transformed into open state from this particular state; Therefore, the computer mode conversion method of the embodiment of the invention also comprises:
When said computing machine is in said particular state, obtain second source state exchange order, said second source state exchange order is used to indicate said computing machine to be transformed into said open state from said particular state;
Respond said second source state exchange order, make said computing machine return to said open state.
When open state enters into the S3 state,, can guarantee the fast quick-recovery of system in system to the power supply of the PCH on the mainboard, internal memory particle (abbreviating internal memory as) and Memory Controller Hub for system's quick-recovery soon.
In system when open state enters into the S4 state; For system can recover, can all information be saved in the hard disk, and keep hard disk and be in the state that can wake up; Under the situation that hard disk is not is not read and write; Its power consumption is low-down, but because the copying data that needs to write hard disk carries out the recovery of system to internal memory, so its toggle speed can be slow.
In specific embodiment of the present invention, guarantee power consumption that said computing machine is in said particular state less than the power consumption under the S3 state through 3 kinds of modes, but resume speed faster than from the S4 recovering state to open state, specify as follows respectively.
In follow-up explanation, as broad as long for closing of operating system and application program with the processing procedure of existing S3, only need to carry out to close, but keep constant the getting final product of data in the internal memory, therefore in subsequent process, do not describe.
< mode one >
In mode one; With the status information of platform controller center P CH to a nonvolatile memory NVRAM; In start-up course, read this information and recover from nonvolatile memory, internal memory and Memory Controller Hub are then kept with the state of S3 constant, in this case; Respond said first power state transition order, make computing machine be in said particular state and specifically comprise:
The configuration information of preserving peripherals is to internal memory;
The status information of preserving platform controller center P CH is to a nonvolatile memory NVRAM;
The power supply of said internal memory and Memory Controller Hub is only kept in the control power supply;
Respond said second source state exchange order, make said computing machine return to said open state and specifically comprise:

Specify as follows.
(this instruction can be sent through variety of way obtaining the order of first power state transition; Except the difference of instruction content, there are not other any differences with the instruction of the existing S3 of switching to state; Be not described in detail at this) after, at first can close application program behind all the information write memories to the application program of running status, the configuration information that further can preserve all peripherals (like network interface card, video card etc.) is to internal memory; The status information that will preserve platform controller center P CH afterwards is to a nonvolatile memory NVRAM; But, also need the state before the closing of application program, the configuration information of peripherals etc., and these are stored in all in the internal memory because computing machine not only to need to recover the status information of PCH; So in specific embodiment of the present invention; In when control power supply, keep the power supply of said internal memory and Memory Controller Hub, but all can cut off the power supply to other equipment simultaneously.
Therefore after getting into predetermined state, the power supply of internal memory and Memory Controller Hub is only arranged, for the S3 state, therefore not power supply of PCH has at least reduced power consumption.
Be described in detail as follows with regard to rejuvenation below.
When the order of said second source state exchange, just begin the power supply that recovers all, certainly, be in power supply state as internal memory and Memory Controller Hub always; So only need recover the power supply of other hardware, and after restoring electricity, can read the PCH status information among the said NVRAM; And carry out the PCH state configuration according to the PCH status information that reads and recover, after this, can carry out initialization operation to other hardware devices; And recovery configuring since before the configuration information of peripherals is saved in internal memory, carry out the configuration restore of peripherals and get final product so directly read this part data from internal memory; Certainly, should be understood that, in whole rejuvenation; All can not internally deposit into capable initialization operation, in order to avoid losing of data wherein causes recovering failure.
After all devices recovers, can handle any task, last operation this moment is exactly to utilize the equipment that recovers to come recovery operation system and application program, and the process of this process and S3 does not have any difference, is not described in detail at this.
For S4; In the method for the embodiment of the invention, all be kept in the internal memory with recovering relevant most information, and internal memory is kept power supply state always; So the data in the rejuvenation directly obtain from internal memory; And need not again it be loaded into internal memory from hard disk, so its resume speed for the S4 state, is accelerated greatly.
< mode two >
Mention, the power consumption under the S3 state comes from 3 parts at least before: internal memory, Memory Controller Hub and PCH, consider the resume speed problem; Internal memory can not cut off the power supply, and therefore in mode two, not only PCH is cut off the power supply; Also Memory Controller Hub is cut off the power supply, with further reduction power consumption.
In specific embodiment of the present invention, need carry out power operation to Memory Controller Hub, but the data in the normally used internal memory are stored by capacitance characteristic; Because electric capacity can discharge, and keep data, will be constantly to its charging; Generally speaking, must periodically internally deposit into row and refresh, otherwise data will be lost; If so Memory Controller Hub is cut off the power supply; Just need utilize certain mechanism to guarantee that the data in the internal memory do not lose, at specific embodiment of the present invention, through being that self-refresh Self-Refresh pattern guarantees that the data in the internal memory do not lose with memory setting.
Said internal memory can keep the data message in the internal memory can not lost after getting into self-refresh mode.
In mode two, respond said first power state transition order, make computing machine be in said particular state and specifically comprise:

Switch in the process of predetermined state at state; With memory setting is the Self-refresh pattern; Only be the power supply of internal memory particle; When the user hoped to recover, internal memory switched to normal mode from self-refresh mode only to be to need just before data in reading internal memory are recovered to handle with the difference of mode one, so other processes are not described in detail at this.
< mode three >
Above-mentioned mode one can be practiced thrift the power supply of PCH, and mode two can be practiced thrift the power supply of PCH and Memory Controller Hub, but should be understood that, only considers that from the angle of power consumption embodiment of the invention also can only be kept the power supply of PCH and internal memory, explains as follows.
Under this mode, respond said first power state transition order, make computing machine be in said particular state and specifically comprise:
