Abstract

PURPOSE:To prevent the excess battery consumption by selectively performing the electric power source disconnection processing or resume processing according to the length of the input operation time of a power source switch even in a resume processing selection mode setting state. CONSTITUTION:The personal computer consists of an input device 30 for data input, a RAM 20 storing the inputted data, a ROM 10 storing a program for controlling this personal computer, a central processing unit 40 performing control according to the program instruction stored in the ROM 10, a power source switch 60 turning on and off the power source of the personal computer, and an output device 50 outputting the processing result. When the system is set to perform the resume processing in turning off the power source switch 60, the power source disconnection processing or the resume processing is selectively performed according to the operation method of the power source switch 60 in operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal computer in which a power-off process or a resume process is selectively performed depending on a method of operating a power switch even in a resume process selection mode.

[0002]

2. Description of the Related Art In a conventional personal computer, when the power switch is turned off during operation, it is divided into the following three patterns.

(1) Regardless of the operating condition, all the memory contents storing the results of the processing contents performed so far are erased, and when the power switch is turned on, the processing is started from the initial state.

(2) Regardless of the operating condition, the state in which the power switch is turned off is stored in the memory, and when the power switch is turned on, the processing is started from the state in which the power switch is turned off. That is, the resume process is always performed.

(3) The power-off process (1) or the resume process (2) is selectively performed.

[0006]

The conventional personal computer has the following problems.

In the case of the above (1), if the power-off process is always performed, the resume process cannot be performed because it does not have the resume process function.

In the case of the above (2), when the resume process is always performed, the resume process is performed even when the resume process is not desired, so that the operation becomes complicated when the power switch is turned on. Since the state in which the power switch is turned off is always stored in the memory, the battery is uselessly consumed.

In the case of the above (3), when the power-off process and the resume process are selectively performed, the resume process is performed even when the resume process is not desired as in the above (2). The operation becomes complicated when the power switch is turned on, and the state in which the power switch is turned off is always stored in the memory, so that the battery is wastefully consumed.

[0010]

SUMMARY OF THE INVENTION The present invention is intended to solve these problems in a personal computer in which the power-off process or the resume process is selectively performed by the operation of turning off the power supply while the battery is being driven. ,
Provided is a personal computer in which power-off processing or resume processing is selectively performed according to the length of input operation time of the power switch even in the resume processing selection mode setting state.

[0011]

According to the personal computer configured as described above, even if the resume process is set to be performed when the power switch is turned off, the power off process may be performed depending on the operating method of the power switch during operation. Alternatively, a wide range of functions are provided because the resume process is selectively performed.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a block diagram of a personal computer showing an embodiment of the present invention, and FIG. 2 is a flow chart for controlling a personal computer showing an embodiment of the present invention.

In FIG. 1, the personal computer of the present invention has an input device 30 for inputting data, a RAM 20 for storing input data, and a ROM 10 for storing a program for controlling the personal computer. And a central processing unit 40 for controlling according to program instructions stored in the ROM 10, a power switch 60 for turning on and off the power of the personal computer, and an output device for outputting the processing result. There is.

Next, the operation in FIGS. 1 and 2 will be described.

The setting means shown in FIG. 1 always stores in the RAM 20 the state in which the power switch 60 is turned off when the power switch 60 is turned off during driving. The resume processing mode is selected so that the processing is started from the state where the operation is performed. In such a state, it is determined whether the personal computer is in operation (step 10),
Various methods are conceivable for this determination method, such as whether the input operation from the input device 30 is performed within a certain time. It is determined whether or not the power switch 60 is pressed in the driving state (step 20), and when the power switch 60 is not pressed, the normal process of step 10 is performed. It is determined whether or not the resume processing mode is selected with the power switch 60 turned off (step 30). It is determined (step 40), and if it is short, the resume process (step 50) is performed. That is, processing for maintaining the power switch 60 in the off state is performed. For example, the off state is stored in the RAM 20.
Next, when the power switch 60 is turned on, the processing is started from the off state. When the pressing time of the power switch 60 is longer than the fixed time, power-off processing is performed (step 60). That is, regardless of the state where the power switch 60 is turned off, the process is always started from the initial value when the power switch 60 is turned on next time.

[0016]

Even when the personal computer of the present invention is set in the resume processing mode, it can be selectively operated in the resume processing mode or the power-off processing mode by changing the input method when the power switch is turned off. Useful battery is not consumed.
