[0013]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a system configuration related to a keyboard / power supply of a portable personal computer of the present invention.

The portable personal computer 1 includes a keyboard / power supply controller 11, a CPU 12, a keyboard 13, an LCD 14, a memory 15, an LCD indicator 16 for displaying test results, an LED 17, and a G / A (gate) for controlling the LCD indicator 16 and the LED 17. Array) 18, an AC adapter 19, a battery A19A, a battery B19B, and the like. Note that the CPU 1
2, the LCD 14 and the memory 15 are used during normal use other than during the assembly inspection, that is, in a normal user use state where a power switch (not shown) provided in the portable personal computer 1 is turned on. Not used for assembly inspection of the invention but included for reference.

The keyboard / power controller 11 is a one-chip microcomputer including a keyboard controller, a power controller, a microprocessor, a RAM, a ROM storing an assembly inspection program, a serial interface, an I / O port, and the like. . The keyboard / power controller 11 detects on / off of the keyboard 13 in a normal user use state in which a power switch (not shown) provided on the portable personal computer 1 is turned on, and the CPU 1
2 outputs the key code information that is turned on / off.

The keyboard / power supply controller 11
Detects a specific key input from the keyboard 13 and
Data control via G / A 18 for turning on / off D17 is performed.

Further, a keyboard / power supply controller 1
1 indicates that the battery A19A is connected to the battery A19A when the AC adapter 19 is connected, regardless of whether a power switch (not shown) provided on the portable personal computer 1 is on or off.
And controls the charge / discharge of the battery B19B, manages the remaining amount and state of each battery, and displays the remaining amount and state on the LCD indicator 16 via the G / A 18.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 2 is a flowchart showing a method for controlling the keyboard / power supply controller of the present invention.
4 is a flowchart of a test mode function of the keyboard / power supply controller of the present invention. The keyboard / power controller 11 starts the operation shown in the flowchart of FIG. 2 when the AC adapter 19 is connected.

First, when the AC adapter 19 is connected,
The operation is started by the power-on reset (step S
21), initialization of the keyboard / power supply controller 11 is performed (step S22).

After the initial setting is completed, the keyboard / power supply controller 11 supplies power to the test use portion. At this time, since the CPU 12, the LCD 14, and the memory 15 are not used in the inspection, power is not supplied (step S2).
3).

The keyboard / power controller 11 determines whether a plurality of predetermined keys on the keyboard 13 are simultaneously pressed. Simultaneously pressing the plurality of keys means starting the test, which makes it difficult for the user to press a specific key for starting the test by mistake, but other methods may be used if the same effect is obtained. Good (Step S
24).

If a plurality of specific keys are pressed at the same time, the keyboard / power controller 11 sets a test mode (step S25).

When the test mode is set, the keyboard / power supply controller 11 detects whether the keyboard 13 is on or off, and controls the battery A19A and the battery B19B.
Control function processing (step S26) and power supply control function processing (step S2) for controlling the remaining amount of power.
Make the settings in 7). If the specific plural keys are not pressed at the same time in step S24, the keyboard / power supply controller 11 does not set the test mode, and performs the power supply control processing for controlling the remaining amount of the batteries A19A and B19B ( Step S27) is set.

After that, the keyboard / power controller 1
1 checks whether the test mode is set, and if so, the test mode function shown in FIG. 3 is processed (step S28). When the test mode is not set, the battery A19A and the battery B1
The remaining amount and status of 9B are displayed on the LCD indicator 16 (step S29).

Next, the operation in the test mode function will be described in detail with reference to FIG.

In the test mode function, pressing of a specific key determined in advance for each item to be tested is checked, and a test pattern is determined and executed based on the key input. Here, in the description, the test pattern A is a display check of the LCD indicator 16 and the test pattern B is an LED1.
7, the test pattern C is for checking the connection of the keyboard 13, and the test pattern D is for checking the connection state and abnormality of the battery.

First, when the specific key A is pressed (step S31), the keyboard / power supply controller 11 determines that the specific key A is the test pattern A, and
The control of all display patterns is performed on the D indicator 16 to check whether the assembly of the LCD indicator 16 is correct (step S32).

When the specific key B is pressed (step S
33), the keyboard / power supply controller 11 determines that the specific key B is the test pattern B,
Is turned on, blinking, and turned off, and it is confirmed whether the LED 17 is correctly assembled (step S34).

When the specific key C is pressed (step S
35), the keyboard / power supply controller 11 determines that the specific key C is the test pattern C, and outputs a key code to be pressed by the keyboard 13 to the LCD indicator 16 to confirm whether the connection of the keyboard 13 is correct. (Step S36).

When the specific key D is pressed (step S
37), the keyboard / power supply controller 11 determines that the specific key D is the test pattern D, and
It outputs various information of the battery 19A and the battery B19B to the LCD indicator 16 to detect the connection state and abnormality of the battery (step S38).
