Abstract

PURPOSE:To protect processing contents by actuating a resume function before the power source of a device is completely interrupted even if a bettery is erroneously removed while an information processing is performed. CONSTITUTION:The removal of a latch 3 which is performed as an action just before removing a battery pack 1 from the battery mounting part 2 of a device main body is detected by a detection part 4 and a detection signal is outputted to a power source control circuit 5. When the power source control circuit 5 inputs the detection signal, it outputs a power off command to a CPU 8. By this command input, the CPU 8 actuates a resume function. Therefore, the processing contents at the time of turning off a power source can be reproduced when the power source is turned on again by effectively actuating a resume function even if a battery is erroneously removed while an information processing is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus equipped with a battery to obtain a power source necessary for information processing.

[0002]

2. Description of the Related Art Conventionally, in an information processing device such as a personal computer, when a power switch is turned off, data and programs being processed are stored in a nonvolatile storage section such as a nonvolatile RAM and the power is supplied again. When the power is turned on, the information that is stored in the non-volatile memory is used to restore the processing contents when the power is turned off.
Function is built in.

Recently, an information processing apparatus has been developed which is equipped with a battery to obtain a power source required for information processing. However, in such an information processing device, if the battery is removed during the information processing, the power supply of the device is turned off before the resume function is activated, and the data in the process is lost. there were. Further, if the battery is removed while accessing an external storage unit such as a floppy disk or a hard disk, the disk information may be destroyed.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem, and even if the battery is accidentally removed during information processing, the device is rejuvenated before the power is completely cut off.
It is an object of the present invention to provide an information processing device capable of operating a video function to protect processing contents.

[0005]

In order to achieve the above-mentioned object, the information processing apparatus of the present invention has a resume function for reproducing the processing contents when the power is turned off and when the power is turned on again. In an information processing apparatus that obtains various power supplies, a CPU, a volatile storage unit that holds data of the CPU, a non-volatile storage unit that can hold data even when the power is turned off, and a battery as a battery mounting unit of the apparatus body. A latch for detachable mounting, a detection unit that detects that the latch has been released, and when the detection unit detects that the latch has been released, the resume function reproduces the processing contents when the power is turned on again. A storage processing unit for storing the data in the volatile storage unit necessary for storing the data in the non-volatile storage unit.

[0006]

In other words, in the present invention, when the detection unit detects that the latch is released, the storage processing unit uses the volatile storage unit necessary for reproducing the processing contents when the power is turned on again by the resume function. Since the data is stored in the non-volatile storage unit, even if the battery is accidentally removed during information processing, the resume function can be activated to protect the processing contents before the power of the apparatus is completely cut off.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram for explaining the configuration of an information processing apparatus according to an embodiment of the present invention.

In the figure, reference numeral 1 is a battery pack having a built-in battery. The battery pack 1 is removably mounted on the battery mounting portion 2 of the apparatus body by using the latch 3. Reference numeral 4 is a detection unit for detecting that the latch 3 is disengaged. The detection unit 4 is realized by, for example, a mechanical contact switch, an optical switch (photointerrupter or the like) using an optical sensor, a magnetic switch using a magnetic sensor, or the like. Further, 5 is a power supply control circuit for controlling power supply from the battery to the main body of the apparatus, 6 is a control function section of the present apparatus, and 7 is an external storage device such as a floppy disk device or a hard disk device.

Further, the control function unit 5 described above fixedly stores a CPU 8 for controlling the apparatus as a whole, a RAM 9 as a volatile storage unit used as a work area of the CPU 8 and an execution program of the CPU 8. ROM10, non-volatile RA as a non-volatile storage unit for storing the contents of RAM9 and the program being executed in the resume operation
It is equipped with M11.

Next, the operation of the apparatus of this embodiment will be described.

When the battery pack 1 is taken out from the battery mounting portion 2 or the latch 3 is accidentally removed, the detecting portion 4 detects this and outputs the detection signal to the power supply control circuit 5. Then, the power control circuit 5 outputs a power-off command to the CPU 8.

The CPU 8 which has input this command stores the contents of the RAM 9 and the program being executed in the non-volatile RAM 11 in accordance with a predetermined power-off sequence, thereby preparing for the continuation of information processing when the power is turned on again. . When the storage of information in the non-volatile RAM 11 is completed, the device power is completely turned off.

At the time when the latch 3 is released, the battery pack 1 itself is in the state of being attached to the battery attaching portion 2, that is, the power of the battery is being supplied to the device, and the above process is actually performed after the latch 3 is removed. This is performed until the battery pack 1 is detached from the battery mounting portion 2.

After that, when the power is turned on again, the nonvolatile R
All the contents stored in the AM 11 are read out and restored in the RAM 9, whereby the information processing when the power is turned off can be continuously performed.

Thus, according to the information processing apparatus of this embodiment, the disengagement of the latch 3 which is performed before the action of actually removing the battery pack 1 is detected by the detection unit 4 and the resume function is activated. Even if the battery pack 1 is accidentally removed during information processing, the resume function can be operated as usual to reproduce the processing contents when the power is turned off when the power is turned on again. In addition, the power-off of the device is a normal system.
Since it is performed according to the can, it is possible to prevent the destruction of information in the external storage device 7 and the destruction of the device itself.

[0017]

As described above, according to the information processing apparatus of the present invention, the detection of the disengagement of the latch, which is performed before the battery is actually removed, and the resuming function is activated, Even if the battery is accidentally removed during information processing, the resume function can be activated effectively and the processing contents when the power is turned off can be reproduced when the power is turned on again.
