The first working condition of the operational order of at least one peripheral hardware is received, and the electronic equipment is in only receive and opens operation
Second working condition of instruction.Below with ACPI (Advanced Configuration and Power
Interface, ACPI) specification for.This energy management can control " switch " system by such as software, can also use
Modem signals wake up and closed system.ACPI has following several modes in operation：
S0：Normally；S1：CPU is stopped.Wakeup time：0 second；S2：CPU is closed, wakeup time：0.1 second；S3：Except
Part outside internal memory is all stopped, wakeup time：0.5 second；S4：Memory information writes hard disk, and all parts are stopped, called out
The time of waking up：30 seconds, (resting state)；S5：Close.
S1=>Standby.Refer to system and be in low power supply supply status, firefly can be set in windows or BIOS
Curtain signal output is closed, hard disc shuts down is in flicker state into armed state, power supply cresset.Now make a motion slide-mouse,
Any key of keypad can wake computer.
S2=>Power Standby.
S3=>Suspend to RAM.It is that all data windows existed now in memory body preserve motionless,
Subsequently into " vacation shutdown ".Now except memory body needs power supply come in addition to keeping data, other units are wholly off
Power supply.
S4=>Suspend to Disk.In being the presence hard disc the complete data in windows memory bodys.Etc. opening
Just directly memory body is read during machine from the place for depositing these data is directly complete, it is not necessary to run application.
S5=>Shutdown.
Furthermore, it is understood that judge the working condition of electronic equipment, or, it is to be in S1 patterns also specifically to judge system
It is the method in S3 patterns, can be with the situation of detecting system：Such as, under ACPI S1 park modes, only CPU stops work
Make, other equipment is still in powering state.And in S3 patterns (BIOS->Power management->Suspend to RAM are set to
Enable, other equipment is in off-position in addition to internal memory).Or, under S3 patterns, system is entirely quiet, is owned
The wholly off work of fan, now system can not be waken up from keyboard, by hand wake up method can only be by the power supply on front panel
Button.
In above-mentioned steps 102, dump energy and working condition based on the electronic equipment obtain the electronics and set

Tag splice mouthful；Wherein, each described target interface obtains control signal by receiving high level or low level；
Accordingly,
The charger chip controls unit 52, for based on the first object interface, the second target interface and
Three target interfaces, the high level being respectively received or low level control signal；
The control signal received by the first object interface, the second target interface and the 3rd target interface is made
For control instruction, the control model for the charger chip is adjusted based on the control instruction.
Such as, referring to Fig. 3, chip shown in figure can be understood as charger chip, it can be seen that chip shown in figure has
Only to therein 6,7,8, these three pins are illustrated in standby multiple pins, the present embodiment, and foregoing three target interfaces can divide
6th, 7,8 these three pins.
The control signal for charger chip is received by 6 shown in Fig. 3,7,8 these three pins, specifically, pipe
Pin 6,7,8 receives CTL1, CTL2 and CTL3 these three signals respectively.
For further, CTL1,2,3 can be understood as information input interface, be mainly used in receiving control model
Switching command.
The control signal that will be received by the first object interface, the second target interface and the 3rd target interface,
For adjusting the control model for the charger chip, in processes, the control of three target interfaces can be believed respectively
Number it is ranked up, the full control signal after sequence is used as adjusting the control model for the charger chip
Control instruction.Generally can be according to the target interface of target interface-the 3rd of first object interface-second, this sequentially comes to control
Signal processed is ranked up.
Referring still to Fig. 3, the signal that CTL1,2,3 are received is ranked up according to the corresponding order in CTL1,2,3, obtained
To corresponding control instruction to switch the control model of charger chip.
Different dump energy, mode of operation, the control instruction of corresponding control model, and control model, can be with
Referring to Fig. 4, CTL1,2,3 regard high level H as 1, low level conduct respectively using high level H or low level L as control signal
0；Such as, when entering SDP1 from CDP, or during from SDP1 into CDP, carried out using Dcp_Auto excessive；
Specifically：
By using aforementioned manner, the dump energy and its mode of operation of electronic equipment can be detected, based on remaining electricity
Amount and mode of operation, when determining that the control model needs of charger chip switch between two target patterns, increase
One only provide charging current transition mode, so as to avoid when charger chip is controlled pattern switching, it is impossible to
The problem of being powered by USB port, it is ensured that the service behaviour of electronic equipment.
