Abstract
The present invention is the automatic test method for power supply of notebook computer. Inside the system of testing power supply of notebook computer, one test program is set to match with test utensil, electronic load machine, multipurpose electric meter, etc to test power supply of notebook computer in advance. Compared with available combined test system mode, the method of the present invention has short test period, and high product performance and quality.
Description
(1) technical field
The relevant a kind of notebook computer power supply automatic detecting method of the present invention refers to that especially a kind of power supply motherboard that can detect notebook is in advance denied good method.
(2) background technology
The power supply of traditional notebook partly when not testing separately, all wants collocation system to do the start test, if motherboard or part have the facts of short circuit then easily to cause motherboard or part to burn situation, and the test duration is quite long.
(3) summary of the invention
A purpose of the present invention is to provide a kind of notebook computer power supply automatic detecting method, can overcome the past is easy to the disappearance that short circuit is burnt to form system mode long, the machine plate spare part of time of body examination examination of putting into effect, and adopts notebook computer power supply automatic detecting of the present invention system can reduce the test duration, increase acceptance rate, improve product production capacity and quality.
Another object of the present invention is to provide a kind of notebook computer power supply automatic detecting method, the power supply motherboard that can detect notebook in advance is not good, and can utilize the bad code concentration problem convenient for maintaining of test.
For further specifying purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
(4) description of drawings
Fig. 1 is the Organization Chart of system of the present invention relevant components.
Fig. 2 is the outside drawing of system of the present invention relevant components.
Fig. 3 is that the present invention is in the computer testing process flow diagram.
Fig. 4 is the process flow diagram of test procedure of the present invention.
(5) embodiment
Seeing also shown in Figure 1ly, is that this is the Organization Chart of system of the present invention relevant components.It comprises power panel 1 to be measured, testing appliance 2, multi-usage ammeter 3, power supply unit 4, Electronic Negative carrier aircraft 5, oscillograph 6, screen 7, computing machine 8 and printer 9 etc.
See also Fig. 3, it is a computer system test flow chart of the present invention.Comprise the following steps:
(1). put and establish power machine plate to be measured on testing appliance 31;
(2). set test function 32, its test function project comprises output voltage, direct current transducer pulse-width modulation frequency, CPU efficient, battery drain stream, battery low-voltage caution, detection shutdown voltage and the battery efficiency of AC leakage current, output dc voltage, test battery saving mode;
(3). according to the test procedure running, test, show and read work 33;
(4). then, whether differentiate unusual 34?
If unusual, then utilize bad code to point out problem points, and print 341, for the direct reference of maintenance person; Otherwise, normal 342, then take out this power machine plate to be measured, treat down that a slice power machine plate to be measured tests.
Like this, can know in advance whether power machine plate to be measured is unusual.
Seeing also Fig. 4, is the process flow diagram of test procedure of the present invention, at first, and is the AC leakage current that detects power machine plate to be measured lower than 0.31 milliampere (mA)? 41.
If be higher than 0.31 milliampere, then expression is unusual, and at this moment, measurement person is promptly with bad code process, and prints; Otherwise, detect output dc voltage test point value and be+5Vo ,+3Vo ,+12Vo? 42.
If not then expression is unusual, at this moment, this measurement person is promptly with bad code process, and prints; Otherwise the output voltage test point value of test battery saving mode is+5Vs ,+3Vs ,+12Vs ,+18Vo ,+15Vo? 43.
If not then expression is unusual, at this moment, this measurement person is promptly with bad code process, and prints; Otherwise is the frequency that detects the direct current transducer pulse-width modulation between 210～300KHz? 44.
If not then expression is unusual, at this moment, this measurement person is promptly with bad code process, and prints; Otherwise, detect CPU efficient and be higher than 88%? 45.
If not then expression is unusual, at this moment, this measurement person is promptly with bad code process, and prints; Otherwise, detect the battery drain flow valuve and be lower than 6 milliamperes? 46.
If not then expression is unusual, at this moment, this measurement person is promptly with bad code process, and prints; Otherwise, detect battery voltage value and be lower than the minimum voltage value of using the battery pattern? 47.With the lithium battery is example, then will be lower than 13.5V; With the Ni-MH battery is that example then will be lower than 11.5V.
If not, then expression is unusual, and at this moment, this measurement person is promptly with bad code process, and prints; Otherwise, detect battery is lower than the battery pattern in the magnitude of voltage of shutdown maximum voltage value? 48.With the lithium battery is example, then will be lower than 11.5V; With the Ni-MH battery is that example then will be lower than 9.5V.
If not, then expression is unusual, and at this moment, this measurement person is promptly with bad code process, and prints; Otherwise, detect battery efficiency and be higher than 80%? 49.
If not, then expression is unusual, and at this moment, this measurement person is promptly with bad code process, and prints; Otherwise it is all normal then to show above-mentioned test function, anticipates promptly, and power machine plate function to be measured is normal.
In sum, by detection method of the present invention, have advantage described as follows:
(1). can improve over form system mode put into effect time of body examination examination long, machine plate part is easy The disappearance of burning in short circuit.
(2). the testing time be can reduce, increase acceptance rate, product production capacity and quality improved.
(3). utilize bad code to point out problem points, be beneficial to the convenient maintenance of maintenance person.
Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
