In embodiments of the present invention, power panel is low to control panel transmission one when determining that external power supply is inputted without electric energy
Level signal, notice control panel external power supply are already off.
Step 504：Shutdown command is sent to computer motherboard using control panel, and continues to send high level letter to power panel
Number.
In embodiments of the present invention, control panel continues after the low level signal for receiving power panel transmission to power panel
Send high level signal so that power panel utilizes the electric energy stored in accumulator, and plate and computer motherboard are powered in order to control, control
Making sheet also sends shutdown command to computer motherboard, and notice computer motherboard external power supply is already off, needs to carry out shutdown behaviour
Make.Specifically, control panel sends the duration of high level signal to power panel, can be according to needed for computer normal shutdown
Time presets the duration, the state of computer can also be detected by control panel, after the completion of determining computer shutdown
Stop sending high level signal to power panel.Power panel is in the whole process for receiving high level signal transmitted by control panel
In, continue the electric energy stored in each energy capacitance set being transferred to control panel and computer motherboard, until no longer receiving control
The high level signal that making sheet is sent.
For example, power panel is passed the electric energy stored in each energy capacitance set by CPCI (compact PCI) motherboard respectively
It is defeated by control panel and computer motherboard.
Step 505：Normal shutdown is carried out to computer using computer motherboard.
In embodiments of the present invention, computer motherboard is after the shutdown command for receiving control panel transmission, by calling journey
The shutdown command of ordered pair computer operating system is called, and realizes the normal shutdown of computer.
For example, when the operating system of computer is Windows systems, computer motherboard is receiving control panel transmission
After shutdown command, if be called to the shutdown command of Windows systems by shutdown command call function, computer is completed
Normal shutdown：
ShellExecute(NULL,NULL,"shutdown","-s-f-t 0",NULL,NULL)。
Step 506：Remaining electric energy in each energy capacitance set is discharged using power panel.
In embodiments of the present invention, after computer motherboard is completed to the normal shutdown of computer, control panel stops to electricity
Source plate sends high level signal, and power panel stops the electric energy storing in each energy capacitance set being transferred to control panel and computer
Mainboard.At this point, power panel is by the positive electrode and negative electrode short circuit of each energy capacitance set after series connection, it will be remaining in each energy capacitance set
Electric energy discharge.
