Kind terminal.
When actual implementation, control equipment 201 is specifically as follows the PC connecting with terminal by the usb 1 03 of terminal
(Personal Computer, personal computer) issues control command from PC to terminal when terminal is open state, controls
Connection between core system 101 and battery 102 disconnects.
Further, above-mentioned power-supply device 202 is specifically as follows programmable power supply, and safety, reliability are higher.
And the connection between power-supply device 202 and the core system 101 of terminal, it can specifically be realized using various ways.
For example, power-supply device 202 can connect core system 101 by usb 1 03；When terminal has audio interface, such as ear
When machine, microphone interface, power-supply device 202 can connect core system 101 by audio interface；When terminal has SIM
When (Subscriber Identity Module, client identification module) card slot, power-supply device 202 can be connected by sim card slot

Step 402, by terminal closedown.
The step can issue shutdown command to terminal from PC and realize, can also directly be realized by manual operation.
Step 403, the connection for disconnecting PC and terminal.
If PC is connect with terminal, PC can power for core system 101, it is therefore desirable to which the connection for disconnecting PC and terminal is cut
Except other power supply units of the core system 101 in addition to programmable power supply.
If above-mentioned steps 402 are directly realized terminal closedown by manual operation, can also first carry out step 403 disconnect PC with
The connection of terminal, then execute step 402 manual operation terminal closedown.
Step 404, confirmation terminal complete shutdown, and the output electric current for detecting programmable power supply is the shutdown leakage current of terminal.
It is described below to using the process of leakage current test system detection terminal standby leakage current shown in Fig. 3, such as
Shown in Fig. 5, comprising:
Step 501, in terminal booting, PC issues control command to terminal, control core system 101 and battery 102
Between connection disconnect.
Step 502, the connection for disconnecting PC and terminal.
Step 503, in terminal standby, the output electric current for detecting programmable power supply is the standby leakage current of terminal.
As it can be seen that connection between the core system and battery of controlling terminal is disconnected using scheme provided in an embodiment of the present invention
It opens, is core system power supply merely with power-supply device, the output electric current of power-supply device, detection are detected when terminal is designated state
Obtained electric current is leakage current of the terminal under the designated state, i.e., it is not necessary that battery 102 under dismantling in terminal, just can
The detection for enough realizing terminal leakage current, and then can guarantee the reliability of end product, and scheme is easily achieved, cost compared with
It is low.
