In addition to having a structure that allows the keyboard to be stored/drawn out, a switch means that controls the power supply on/off in conjunction with the stored/drawn state and transmits the stored/drawn state to the CPU, and a program that was previously running when the keyboard was stored. The present invention is characterized by comprising means for supplying a power off signal to the power supply unit after saving the state information of the program, and means for restoring the state information of the program and continuing the operation when the keyboard is detected to be pulled out. shall be.

(Function) The present invention has a structure in which the keyboard can be pulled out from or incorporated into the computer main body, thereby saving space in a laptop personal computer. When the laptop computer is turned on and stored in the two main units (when assembled properly)
To facilitate operation, activate resume and turn off the power. In other words, the laptop personal computer has a structure that allows the keyboard to be housed (incorporated) in the casing of the laptop personal computer when not in use, and the keyboard can be stored/incorporated.
A switch is provided to turn on/off the main unit's power depending on the pulled-out state, and the resume activation is performed in conjunction with the power control, thereby saving space and improving operability of the top personal computer.

By adopting the above configuration, the power to the device can be turned on simply by pulling out the keyboard contained in the laptop or <-sonal computer from the device main body, and when the keyboard is installed (stored) in the device main body, the power is automatically turned on after resume processing. The device can be turned off automatically, making the device more compact, easier to operate, and saving power.

(Example) Hereinafter, an example of the present invention will be described using the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention; FIG. 1(a) shows the external structure when the keyboard is stored, FIG. 1(b) shows the external structure when the keyboard is pulled out, Figure c) shows the keyboard in the locked state when the keyboard is in the retracted state, and Figure (d) shows the keyboard in the unlocked state when the keyboard is in the retracted state.

In the figure, reference numeral 1 denotes a laptop personal computer main body, which has a keyboard 11 that can be pulled out with a sliding drawer structure and is built into the main body when not in use, and is further equipped with a display 12, a hard disk drive (HDD) 13, etc. There is. The keyboard 11 has a form that can be drawn out/stored, and is pulled out from the double-top personal computer main body 1 when in use, and stored within the double-top personal computer main body 1 when not in use. The display 12 is rotatably provided on the laptop personal computer main body 1 via a hinge mechanism.
