Description of drawings
Fig. 1 is the workflow diagram of the inventive method preferred embodiment.
Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The present invention program's thinking is when the user presses the shutdown of computer power switch key, fast data in the current internal memory and computer equipment duty is kept in the storage unit, cuts off the electric power system of computer equipment then; When opening computing machine, recover to go back in the data that will be kept in the storage unit.So computing machine one start can return to the duty before computing machine cuts out rapidly, interferes and need not the user.
Below the preferable embodiment of the present invention is described in detail explanation.
Storage unit of the present invention can adopt various memory devices, as: portable hard drive, the flash memory of band USB interface, and the hard disk of computing machine self etc.Factor such as combination property, cost considers to adopt the computing machine self EMS memory as storage unit in the present embodiment, because internal memory needs continued power, therefore need power supply to be provided for internal memory separately, or existing computer power supply system transformed, make it under off-mode, also can be continuously the internal memory power supply.
In addition, in order to deal with the generation of unexpected power-off condition, also need to provide an interim power supply, when having a power failure, by the power supply of interim power supply, cut off interim power supply again after transferring to the data in the internal memory in the hard disc of computer, interim power supply can adopt the rechargeable battery of common capacity.A hardware controls module also to be arranged simultaneously, realize that instant reflection power environment changes, provide power supply timely blocked operation, and send look-at-me notice computer operating system.The hardware controls module can have multiple production program, such as being made of voltage comparator, power change-over switch and a diode.
And in BIOS, implant corresponding software control module, control BIOS carries out various dormancy, arousal function, the reflection external power supply state variation look-at-me that the action of responsive computer power switch key and hardware controls module are sent, and impel operating system to enter corresponding work mode.
The workflow that present embodiment is concrete, referring to shown in Figure 1:
The user when for the first time plugging the external power supply start, when promptly computing machine starts for the first time, this moment storage unit be in the internal memory without any information, then operating system can start i.e. BIOS self check, and pilot operationp system, loading application programs automatically according to normal sequence.
When the user presses the shutdown of computer switch key, it is to supress power switch key that BIOS detects, so send system's control interruptive command to operating system, operating system stops current all programs of moving at once, the duty of current device is saved in the internal memory, enter the internal memory sleep mode state, and notice BIOS, BIOS cuts off the electric power system of all internal memories with external equipment.The needed time of this process probably is 1～2 second, and by comparison the unused time of general case operating system be 10～40 seconds, and need the user to interfere.
Wherein, the internal memory sleep mode state is meant internal memory by power supply power supply and enter the self-refresh state, to protect the data in the current internal memory.The power supply this moment required power consumption of self-refresh for the memory modules power supply and when providing internal memory to preserve data only, this power consumption is very low, only needs 0.2W usually.When cutting off computer power support system, can adopt the open mode of software control reserved memory electric power system, also the electric power system of internal memory directly can be linked to each other with external power supply, make it not be subjected to the restriction of computer on/off.
When the user presses the power switch key start, all devices restores electricity, the state that the BIOS self check is judged before the start is the internal memory sleep mode state, so notifying operation system, operating system will originally be kept in the internal memory corresponding data and write back in the equipment, allow the equipment full recovery to original duty.The needed deficiency of time of this process 1 second, be 1～2 minute the normal start-up time of comparing the normal operations system.
This process need not to be provided with especially for the general operation system just can be finished automatically.Usually BIOS judges internal memory and is in dormant state in self check, can be automatic the notifying operation system carry out wake operation, so system with regard to moment ground get back to user's preceding duty of shutting down.
As long as external power supply exists, user's switching on and shutting down action will be carried out according to step 2,3 always, so realizes the instant on switch machine of this operating system, all preservations and recovery action need not the user be interfered, the user only need click the computer switch key and get final product, and simple and fast is safe and reliable.
Two kinds of possible fortuitous events more below:
The unexpected power failure when operating system is moved.The hardware controls module will be enabled interim power supply automatically and be kept current power supply and produce a look-at-me notifying operation system, operating system detects the generation of this look-at-me, the duty and the data in the internal memory of current each equipment are saved in the hard disk, notify BIOS after entering the hard disk dormant state, close all electric power systems by BIOS.
Up to when external power supply restores electricity, computing machine after the operation BIOS self check, is returned Auto Power On with the recovering state before the power failure that is kept in the hard disk, continue the task before operation has a power failure.
Wherein, in order to save the power consumption of interim power supply, also can make interim power supply not to power devices such as displays, specifically can not realize by making interim power supply with modes such as display are connected, a switch also can be set, select whether to need to be monitor power supply by the user.The sign of dormant state can be added with when hard disk is in dormant state usually in inside, when operating system detects this sign, wake operation will be automatically performed.For the operating system that does not have the hard disk dormant state, can in BIOS, the implant procedure section allow BIOS carry out this operation.
The unexpected power failure when system is in the internal memory sleep mode state, just system is in off-mode unexpected power failure of following time.The hardware controls module will start the power supply of interim each hardware device of power up computing machine automatically, wherein also can make it not open display by setting, BIOS judges before this, and state is the internal memory sleep mode state, so the data that the notifying operation system will originally be kept in the internal memory write back in the equipment, allow the equipment full recovery to original duty, to judge current power supply be that interim power supply provides to the hardware controls module then, so produce a look-at-me notifying operation system, operating system detects the generation of this look-at-me, the duty and the data in the internal memory of current each equipment are saved in the hard disk, notify BIOS after entering the hard disk dormant state, BIOS closes all electric power systems.
Up to when external power supply restores electricity, the computing machine Auto Power On, BIOS finishes the recovering state before this that self check and notifying operation system will be kept in the hard disk and returns, BIOS forces to allow operating system enter the internal memory sleep mode state then, be that operating system stops current all programs of moving at once, the duty of current device is saved in the internal memory, enter the internal memory sleep mode state, and notice BIOS, BIOS cuts off the electric power system of all internal memories with external equipment.When thereby the user pressed on ﹠ off switch next time, moment can be got back to the preceding one action state of user by the assurance system.
The method of the previous state of preservation provided by the invention and fast quick-recovery computer working is applicable to most computing machine and computer operating system.By the time that simple equipment adds and software setting just can very effective minimizing switching on and shutting down be spent, the user only need press power switch key can realize the high-speed switch machine, avoid shut down needed manual-lock application program and preserve data of user, reduce period of reservation of number.And saved system current state at any time when accident has a power failure is avoided loss of data, destruction or system crash, increases work efficiency and the security of system.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
