Embodiment
In the computer mode conversion method of the embodiment of the present invention and device, preserved by the data needed by System recover the power consumption reduced when computing machine is switched to standby by various mode, but the time that simultaneous computer recovers is lower again.
The computer mode conversion method of the embodiment of the present invention, for a computing machine, when described computing machine be in suspend to internal memory STR state time, the power consumption of described computing machine is the first power consumption; When described computing machine is from suspending to hard disk STD State Transferring to open state, the consuming time of described computing machine is the first amount consuming time, it is characterized in that, described computer mode conversion method as shown in Figure 1, comprising:
Step 11, when described computing machine is in described open state, obtain one first power state transition order, described first power state transition order is used to indicate described computing machine and converts particular state to from described open state;
Step 12, responds described first power state transition order, makes computing machine be in described particular state;
Wherein, the power consumption that described computing machine is in described particular state is the second power consumption, and described second power consumption is less than described first power consumption; It is the second amount consuming time that described computing machine is transformed into the consuming time of described open state from described particular state, and described second amount consuming time is less than the first amount consuming time.
The specific embodiment of the invention is by the order of response first power state transition, computing machine is made to enter described particular state, be less than the power consumption of S3 state at this particular state power consumption, but its resume speed is more very fast than suspending to hard disk STD state again, achieves the balance of resume speed and power consumption.
In a particular embodiment of the present invention, described particular state is different from any one state that ACPI (ACPI, AdvancedConfigurationandPowerInterface) specification defines.
Certainly, system is transformed into after the particular state the application's specific embodiment from open state, when user needs to continue to use computing machine, also needs to be transformed into open state from this particular state, therefore, the computer mode conversion method of the embodiment of the present invention also comprises:
When described computing machine is in described particular state, obtain a second source state transition command, described second source state transition command is used to indicate described computing machine and is transformed into described open state from described particular state;
Respond described second source state transition command, make described computing machine return to described open state.
When system enters into S3 state from open state, in order to system can quick-recovery soon, to the power supply of the PCH on mainboard, memory grain (referred to as internal memory) and Memory Controller Hub, the fast quick-recovery of system can be ensured.
When system enters into S4 state from open state, in order to system can be recovered, can all information be saved in hard disk, and maintain hard disk and be in a state that can wake up, when hard disk is not is not read and write, its power consumption is low-down, but owing to needing the recovery data copy of write hard disk being carried out system to internal memory, so its toggle speed can be slow.
In a particular embodiment of the present invention, ensure that power consumption that described computing machine is in described particular state is less than the power consumption under S3 state by 3 kinds of modes, but resume speed is faster than from S4 recovering state to open state, is described in detail as follows respectively.
In follow-up explanation, for operating system and the closedown of application program and the processing procedure of existing S3 as broad as long, only need to perform closedown, but data in maintenance internal memory are constant, therefore do not describe in subsequent process.
< mode one >
In mode one, by the status information of platform controller center PCH to a nonvolatile memory NVRAM, read this information to recover from nonvolatile memory in start-up course, internal memory and Memory Controller Hub are then maintained and the state of S3 constant, in this case, respond described first power state transition order, make computing machine be in described particular state and specifically comprise:

Be described in detail as follows.
In the order of acquisition first power state transition, (this instruction sends by various mode, except the difference of instruction content, other any difference is not had with the instruction of the existing S3 of being switched to state, be not described in detail at this) after, first application program can be closed to after all information write memories of the application program of running status, all peripherals can be preserved further (as network interface card, video card etc.) configuration information to internal memory, the status information of platform controller center PCH will be preserved afterwards to a nonvolatile memory NVRAM, but because computing machine recovers the status information not only needing PCH, also the state before the closedown of application program is needed, the configuration information etc. of peripherals, and these are all stored in internal memory, so in a particular embodiment of the present invention, when power supply control, maintain the power supply of described internal memory and Memory Controller Hub, but simultaneously all can power-off to other equipment.
Therefore after entering predetermined state, only have the power supply of internal memory and Memory Controller Hub, for S3 state, at least PCH does not power, because this reducing power consumption.
Be described in detail as follows below with regard to rejuvenation.
When described second source state transition command, just start to recover all power supplies, certainly, be in power supply state as internal memory and Memory Controller Hub always, so only need the power supply recovering other hardware, and after restoring electricity, the PCH status information in described NVRAM can be read, and carry out the configuration restore of PCH state according to the PCH status information read, after this, initialization operation can be carried out to other hardware devices, and recovery configuring, owing to the configuration information of peripherals being saved in internal memory before, so directly read from internal memory the configuration restore that this part data carries out peripherals, certainly, should be understood that, in whole rejuvenation, all can not internally deposit into row initialization operation, in order to avoid the loss of wherein data, cause recovering unsuccessfully.
After all devices recovers, can process any task, now last operation is exactly utilize the equipment recovered to come recovery operation system and application program, and the process of this process and S3 there is no any difference, is not described in detail at this.
For S4, in the method for the embodiment of the present invention, the most information relevant to recovery are all kept in internal memory, and internal memory maintains power supply state always, so the data in rejuvenation directly obtain from internal memory, and again it need not be loaded into internal memory from hard disk, so its resume speed is for S4 state, greatly accelerate.
< mode two >
Mention, the power consumption under S3 state at least comes from 3 parts: internal memory, Memory Controller Hub and PCH, considers resume speed problem before, the impossible power-off of internal memory, therefore in mode two, not only carries out power-off to PCH, also power-off is carried out to Memory Controller Hub, to reduce power consumption further.
In a particular embodiment of the present invention, need to carry out power operation to Memory Controller Hub, but the data in normally used internal memory store by capacitance characteristic, because electric capacity can discharge, maintain data, will constantly to its charging, generally, periodically must internally deposit into row to refresh, otherwise data will be lost, if so carry out power-off to Memory Controller Hub, utilize certain mechanism to ensure that the data in internal memory are not lost with regard to needing, in specific embodiments of the invention, by being that self-refresh Self-Refresh pattern ensures that the data in internal memory are not lost by memory setting.
After described internal memory enters self-refresh mode, the data message in internal memory can be kept to be lost.
In mode two, respond described first power state transition order, make computing machine be in described particular state and specifically comprise:
Preserve the configuration information of peripherals to internal memory;
Arrange described in save as self-refresh Self-Refresh pattern;
Preserve the status information of platform controller center PCH to a nonvolatile memory NVRAM;

The configuration restore of peripherals is carried out according to the configuration information recorded in internal memory;
The recovery of operating system and application program is carried out according to the data recorded in internal memory.
Be switched in the process of predetermined state in state, be Self-refresh pattern by memory setting, only for memory grain is powered, when user wishes to recover, only be before carrying out Recovery processing, to need just internal memory to switch to normal mode from self-refresh mode reading the data in internal memory with the difference of mode one, therefore other processes are not described in detail at this.
< mode three >
Above-mentioned mode one can save the power supply of PCH, and mode two can save the power supply of PCH and Memory Controller Hub, but should be understood that, only consider from the angle of power consumption, the invention process example also only can maintain the power supply of PCH and internal memory, is described as follows.
In this manner, respond described first power state transition order, make computing machine be in described particular state and specifically comprise:
Preserve the configuration information of peripherals to internal memory;
