DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resume function for temporarily stopping the operation of an input / output device such as a display unit or a disk device when a user temporarily suspends processing in a personal computer or the like. The present invention relates to a resume control device to be realized. Further, the present invention relates to a battery protection device for preventing the battery from being consumed when switching from a commercial power supply to a built-in battery in a portable personal computer or the like.

[0002] A user does not always use a personal computer (hereinafter, abbreviated as a personal computer), and may interrupt processing by the personal computer to perform another job. At this time, if the display unit of the personal computer, the disk device, and the like are driven in the same manner as when the personal computer is used, useless power is consumed. On the other hand, if the power of the entire PC is turned off, power is not wasted, but the contents of the memory are also cleared, so it is necessary to load the programs and data into the memory again and start up the PC. Must.

In addition to preventing wasteful power consumption as described above, initial program loading (IPL) is performed again.
In order to eliminate the need for processing, instead of turning off the power of the entire personal computer, resume only temporarily stopping the power supply to the display unit and disk device while retaining the contents of the memory, and temporarily suspending the operation. Function is realized.

Incidentally, a personal computer is connected to a communication line or a local area network (LA) via a communication adapter device.
N), many users use network processing to operate as a terminal of a large computer or to perform file transfer processing between personal computers. Accordingly, personal computers with a built-in communication adapter device such as a line adapter device or a LAN adapter device have been realized, and such a personal computer is configured to supply power to the communication adapter device from the personal computer body side. . For this reason, there is a need for a resume function that includes stopping the supply of power to the communication adapter device.

[0005] In addition, the number of users who perform similar network processing using a portable personal computer is increasing. However, in the case of a portable personal computer, since the power consumption of the communication adapter device is greater than the capacity of the built-in battery, power is supplied from a commercial power source via a power cord when performing network processing. It is necessary. For this reason,
Prevents the battery from being consumed due to the power consumption of the communication adapter device when the battery mode is switched to the battery mode in which power is supplied from the battery due to the plug of the power cord being disconnected from the outlet during the execution of network processing. There is a need for a battery protection device.

2. Description of the Related Art As shown in FIG. 7, a conventional resume control device includes a resume processing unit 711 and a soft switch 721 for controlling power on / off of each input / output device. The user inputs a resume instruction to the resume processing unit 711 by pressing a resume key provided on the keyboard.

In response to the resume instruction, the resume processing unit 711 first inquires of the device driver 701 of each input / output device such as a display unit and a disk device whether or not the operation can be stopped. When we receive a notification that this can be stopped,
The resume processing unit 711 controls the power supply circuit 731 via the soft switch 721 corresponding to the input / output device.
, And supply of power to the input / output device is stopped.

As described above, the power supply to the display unit and the disk device provided in the personal computer is temporarily stopped, so that the power consumption can be suppressed. In this case, the state of the process started by the user is held in the memory, and the contents of the display memory are also held. Therefore, when the resume processing unit 711 operates each of the soft switches 721 to resume the supply of power when the user presses the resume key again and instructs to cancel the resume state, the user can resume the resume operation. Processing can be resumed in the same state as when the instruction was input.

In the case of the resume control device described above, power is continuously supplied to the communication adapter device (not shown) even in the resume state in consideration of the fact that the network process is not a process closed only inside the personal computer. Was. In this case, since the connection state of the line that is a physical communication path and the connection state of the session that is a logical communication path are both held, network processing can be performed at any time in response to an instruction from the user to cancel the resume state. Can be resumed.

[0010] Further, in response to the resume instruction, the resume processing unit 711 first urges the user to stop the network processing via a display unit or the like, and in response to the instruction of the user via the communication adapter device. There is also a resume control device configured to disconnect a communication path set in advance and then stop supplying power to the communication adapter device.

FIG. 8 shows a configuration of a conventional battery protection device. 8, a power conversion unit 801 generates driving power of each unit from an alternating current supplied from a power supply cord connected to a commercial power supply, and outputs an output of the power conversion unit 801 and an output of the battery 104. One is supplied to the display unit or the communication adapter device via the switching circuit 802.

A power supply monitoring unit 803 monitors a supply state of the AC power to the power conversion unit 801 described above.
When the supply of AC power is stopped, it is determined that the plug of the power cord has been disconnected from the outlet, the switching circuit 802 is instructed to switch to the battery 104, and the operation system (OS) 811 is notified of the fact.

In response, the operation system 8
11 requests the display control unit 821 to display a message indicating that the power cord has been disconnected from the outlet.
21 and the display unit perform the above-described message display process to prompt the user to reconnect the power cord, thereby preventing the battery 104 from being consumed.

In this case, the electric power from the battery 104 is continuously supplied to each unit including the communication adapter via the switching circuit 802.

[0015]

As described above, the conventional resume control device continues to supply power to the communication adapter device even in the resume state.
Therefore, in addition to the power required to hold the contents of the memory, the power required to operate the communication adapter device is required, so that the power consumption of the entire personal computer can be suppressed even when the system shifts to the resume state. Did not.

On the other hand, if the communication path is disconnected in response to the resume instruction, it is not necessary to supply power to the communication adapter device during the resume state, so that power consumption in the resume state can be suppressed. However, if the power supply to the communication adapter device is cut off, the control programs and data in the memory built in the communication adapter device are naturally lost. Need to be loaded.

Here, conventionally, it has been assumed that the power of the communication adapter device is not cut off after the personal computer is started. Therefore, the control program is loaded into the communication adapter device at the same time when the personal computer is started. It has become. For this reason, in order to load the control program into the line adapter device, the user needs to end other processing once and perform IPL again.

Further, when this method is used, when shifting to the resume state, the user needs to once instruct the disconnection of the session. After loading the program, it was necessary to instruct again to establish a session with the partner processing device.

Further, the conventional battery protection device notifies the user that the power cord has been disconnected and urges the user to connect the power cord. However, the user is asked whether or not to connect the power cord. It is up to you. For this reason, when the user does not notice the displayed message, the battery may be consumed due to the power consumption of the communication adapter device, and the contents of the memory may be lost.

An object of the present invention is to provide a resume control device capable of temporarily stopping the operation of a communication processing function. Another object of the present invention is to provide a battery protection device that automatically reduces power consumption and prevents battery consumption when the mode is shifted to the battery mode.

It becomes possible. In this case, the management of the battery 104 is not left to the user, but the battery 104 can be protected by the personal computer, so that the serviceability to the user can be improved.

In this case, the processing of the communication process 205 is temporarily interrupted in accordance with the shift to the battery mode, so that the mode switching unit 304 temporarily activates the network processing function together with a message indicating that the power cord has been disconnected. What is necessary is just to display the message to the effect that it stops temporarily on a display part, and to notify a user.

When relaying the battery mode notification as a resume instruction, the relay unit 312 transmits the notification
14 is instructed to suspend the session disconnection completion notification. In response to this, the notification suspending unit 214
The session disconnection completion notification from the device driver 222 is suspended. Therefore, the communication process 205
Is in a sleep state waiting for a session disconnection completion notification during the battery mode.

Thereafter, when the user inserts the power cord into the outlet, in response to the notification from the power monitor 302,
The mode switching unit 304 sends a battery mode release notification to the network control unit 311.

In response to the battery mode release notification, a resume release instruction is notified to the network control process 231 by the relay unit 312. In response, the reception processing unit 232 and the instruction issuing unit 233 operate, and the power is turned on. The instruction is transmitted to the device driver 222 via the communication control unit 212.
Sent to In response to this instruction, the device driver 2
22 sets the corresponding bit of the register 241 so that the line adapter 204
Power supply to the power supply is started, and the power supply restart function of the power supply control unit 123 is realized.

In this way, when the power supply from the commercial power supply is resumed by the user plugging the power cord into the outlet, the power supply to the line adapter device 204 is automatically turned on again. Becomes possible.

In the same manner as the resume canceling operation shown in FIG. 5, the network control process 231 sends a download instruction to the download processing unit 215 and starts the download process of the line adapter device 204.
In addition, in response to the completion notification of the download processing, the main body resource activation instruction is transmitted to the communication control unit 212, and the protocol control driver 221 and the device driver 222 are made operable. Thus, the line adapter 204 can be automatically made available again in response to the release of the battery mode.

As described above, the notification suspension unit 214
Suspends the session disconnection completion notification, and
By setting No. 5 to a disconnection completion notification waiting state, the communication process 205 is prevented from repeating the session establishment request. As a result, other processes operating in the battery mode can operate without being hindered by the communication process 205, and a decrease in the processing efficiency of these processes can be prevented. Here, since the communication process 205 is often given a high priority, the effect of putting the communication process 205 in the sleep state as described above so as not to hinder the operation of other processes is as follows. large.

Further, the communication control unit 212 instructs the notification suspension unit 214 to release the suspension in response to the completion notification of the device driver 222 in response to the main body resource activation instruction, and the communication suspension unit 214 suspends the suspension. By notifying the communication process 205 of the completion of disconnection of the session, the communication process 205 can be prompted to connect the session, and the function of the restart instructing unit 122 can be realized.

As a result, the communication path can be automatically reconnected in response to the release of the battery mode.
The communication process by the communication process 205 can be restarted. Therefore, there is no need for the user to give an instruction to establish a session, and the user can save time and effort.

[0075]

As described above, the first aspect of the present invention is:
According to the resume instruction and the resume cancel instruction, the power supply to the communication adapter device can be cut / restarted, and the communication path can be cut / reconnected, so that the resume function including the network processing function can be realized. Is possible. As a result, it is possible to suppress the power consumption of the personal computer in the resume state, and to save the user's trouble in shifting to the resume state and canceling the resume state.

According to a second aspect of the present invention, the power supply to the communication adapter device is cut / restarted in response to the battery mode instruction and the battery mode release instruction.
When shifting to the battery mode, it is possible to automatically reduce power consumption, prevent the battery from being excessively consumed, and protect the battery without relying on the user. Furthermore, once the communication path is cut off in response to the battery mode instruction, the communication path can be automatically reconnected in response to the battery mode release instruction without bothering the user. It is possible to save the user's trouble in the case where the user comes off.
