Abstract

PURPOSE:To continue an interrupted program by next power-ON operation by bringing a resuming function automatically when a display housing is closed. CONSTITUTION:When a user closes the display housing during lap-top personal computer operation, a CPU 1 is informed of the closure state of the display housing through a switch 3. The CPU 1 on recognizing this state carries resuming processing into effect and turns of a power source unit 4. Then when the user opens the display housing, the CPU 1 knows the state through the switch 3 and then turns on the power unit 4 to perform restoration processing for resuming and carry on the execution of the program from the last interrupted state. Consequently, when the display housing is opened and closed, the program is saved automatically by the resuming processing and the process is restored automatically to the operation state right before the power source is turned off.

Laptop personal computers use flat type display devices such as LCDs, and are often battery-powered, so power-saving designs can be seen everywhere.

Additionally, support for the resume function is essential to improve operability. The resume function is to turn off the power.
This means that all state information necessary for the currently running program is retained even when the power is turned off, and the program continues to be executed when the power is turned on.

(Problem to be Solved by the Invention) By the way, in a laptop-type personal computer, an / By opening the display housing via a hinge mechanism, the display surface of the display device is set and held at a position that is easily visible to the operator, and when the display device is not operated, the display housing is closed, and the main body including the keyboard is closed using the display housing as a lid. It has a structure that keeps it set in the position that covers it. The time when the display housing is closed is generally when the user ceases use. Therefore, in order to save power, it may be possible to automatically turn off the power when the display housing is closed, but on the other hand, the power may turn off at an unexpected time, causing problems such as data loss.

The present invention has been made in view of the above circumstances, and provides a laptop personal computer that automatically resumes when the display housing is closed and continues executing the program when the power is turned on next time. The purpose is to provide a personal computer that can perform the following functions.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a display housing in which a display device is mounted to a computer main body including a keyboard, which is attached to the computer body via a hinge mechanism so as to be openable and closable, and when the keyboard is operated. By opening the display housing via the hinge mechanism, the display surface of the display device is set and held at a position that is easily visible to the operator, and when the display housing is not operated, the display housing is placed in a position that covers the main body including the keyboard by closing the display housing. a personal computer configured and held as a lid body, the personal computer has a switching means for detecting the open/closed state of the display housing, and when the display housing is in the closed state, a signal obtained through the switching means is used to perform the previous execution. a means for saving state information of the program that was being turned off to an internal memory and supplying a power-off signal to the power supply unit; and a means for reading the program state information immediately before the power-off from the internal memory when the display housing is in an open state; The program is characterized by comprising means for restoring the operating state immediately before the shutdown and restarting program execution.

(Function) In the above configuration, when the display 1 housing is closed during operation, a signal from a switch that detects this causes the state information of the program being executed at that time to be memorized and the power is turned off. Thereafter, when the display housing is opened, the state information of the program that was running when the display housing was last closed is restored by the signal from the switch that detects its open/closed state.
Programs can be executed continuously. That is, a personal computer that can be resumed using a power switch is provided with a switch that detects opening and closing of the display housing.
This switch controls resume processing. This prevents scandals such as closing the display housing while the power is on and forgetting to turn it off.
It can contribute to power saving and high reliability.

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

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, reference numeral 1 is a CPU that controls the entire device.

Reference numeral 2 is a power switch, which turns the power of the computer body 0N10FF (on/off). Reference numeral 3 is a micro switch, which is integrated with the disc fly housing and changes to 0N10 by opening and closing the disc fly housing.
It will be FF. 0N10FF of this micro switch 3
(on/off) information is transmitted via an input/output port (not shown).
Sent to PUI for reference. Reference numeral 4 denotes a power supply unit, which has a built-in 1-chip microcomputer, and performs power ON/OFF (ON/OFF) control, battery remaining capacity check, etc. based on instructions from the main body CPU.

FIG. 2 is a flowchart showing the operation of the embodiment of the present invention.

The operation of the embodiment of the present invention shown in FIG. 1 will be described below with reference to FIG.

When a user closes the display housing while operating a laptop personal computer, the closed state of the display housing is notified to the CPUI via the switch 3. When the CPUI recognizes this state, it executes a resume process according to the procedure shown in FIG. 2, and instructs the power supply unit 4 to power off.

The next time the user opens the display housing, the CP
U1 learns the status from the switch 3, turns on the power supply unit 4, performs the resume restoration process, and
Continues program execution from the state where it was last interrupted.

Note that the resume processing described in the present invention refers to the resume processing that occurs when the user turns off the computer while running a program.
This is a process in which the operation being performed at that time is memorized, and the next time the power is turned on, the program is returned to the previous one.

[Effects of the Invention] As described above, according to the present invention, a display device is rotatably attached to a computer body including a keyboard via a hinge mechanism, and when the keyboard is operated, the display device is attached to the display housing via the hinge mechanism.
