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 rechargeable battery, and to an appropriate suspend process executed when the remaining battery power becomes low.

[0002]

2. Description of the Related Art A portable information processing apparatus such as a notebook personal computer usually has a built-in rechargeable battery and has an advantage that it can be used outdoors such as in a train or a car. In such a general-purpose window system installed in a notebook computer, when there is no operation within a set time or when the battery level is extremely low, suddenly when there is no operation so that the power charged in the rechargeable battery is not wasted A suspend function is standard equipment to prevent data destruction caused by system stoppage. The suspend function provided when the battery is low, that is, when the battery is low, includes a normal suspend method and a critical suspend method, and one of the suspend methods is selected and preset for each notebook personal computer.

[0003] The normal suspend method is as follows.
An inquiry is made to all the activated applications as to whether or not suspending is possible. When all the applications respond that suspending is possible, the suspending process is executed. That is, the power is turned off after the contents of the memory are stored in a non-volatile disk device. If at least one application does not return a response indicating that suspension is possible, the suspend process ends without saving the contents of the memory. In the critical suspend method, the suspend process is forcibly executed without inquiring about whether the suspended application can be suspended.

As described above, if the contents of the memory are stored in the disk device, after the battery has been charged or the power has been supplied from the AC power source, the contents are stored in the disk device by a resume process executed when the system is started. The contents are expanded on the memory. Thus, the processing executed by each application before the execution of the suspend processing can be continuously performed.

[0005]

However, in the normal suspend system provided by the conventional window system, the suspend process is not executed when any application replies that suspend is not possible.
After that, the system had to be operated without knowing when the power supply from the battery was stopped. For this reason, data that exists only in the memory but is not stored may be lost.

In the critical suspend method,
The suspend process was forcibly executed regardless of the state of the running application. For example, even if there is an application that is in the process of communicating with another system, the application is forcibly terminated without executing a process of disconnecting a communication line between the applications. In other words, even if the suspend process can be performed normally, from the viewpoint of the communication partner, the communication process is terminated. For this reason, even if an attempt is made to resume communication with another system after the resume processing, a communication error often occurs.

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

Embodiment 1 FIG. 1 is a functional block diagram showing the first embodiment of the information processing apparatus according to the present invention mounted on the information processing apparatus. The information processing apparatus employing the present embodiment is an apparatus equipped with a rechargeable battery 1 such as a notebook personal computer. This information processing apparatus incorporates a general-purpose window system, and the above-described normal suspend method and critical suspend method are provided as suspend functions when the power capacity of the battery 1 becomes low. FIG. 1 shows a low battery detection unit 2, a timer interrupt generation unit 3, a suspend processing execution unit 4, an application execution control unit 5, and an application execution unit 6 that constitute a battery remaining power warning unit. The low battery detection unit 2 constantly monitors the power capacity of the battery 1 and detects when the remaining battery capacity becomes equal to or less than a preset threshold as a low battery state. The timer interrupt generation unit 3 is an interrupt signal generation unit that repeatedly sends out an interrupt signal at regular time intervals when the low battery detection unit 2 detects a low battery state. The suspend process execution unit 4 executes a process using the normal suspend method each time the interrupt signal transmitted by the timer interrupt generation unit 3 is received, and executes a critical suspend process when the number of received interrupt signals reaches the number of forced suspends. Executes processing according to the method. The application execution control unit 5 controls the execution of the application executed by the application execution unit 6, such as starting the application in response to the application start request. In the present embodiment, in particular, in the present embodiment, the remaining battery power becomes equal to or less than the threshold. After that is detected, the activation of a new application is prevented.

In the configuration of the present embodiment, the functions of the low battery detection unit 2 and the timer interrupt generation unit 3 can be realized by configuring a circuit. The functions of the suspend processing execution unit 4 can be realized by the BIOS of the window system. The functions of the application execution control unit 5 and the application execution unit 6 are the functions of the window system having the functions or the applications running on the window system by the CPU. It is realized by being executed.

A characteristic feature of the present embodiment is that when the battery 1 is in the low battery state, the normal suspend method is executed a certain number of times. That is, when the number of times of forced suspension has been reached, the process by the critical suspend method, that is, the suspend process is forcibly executed. In other words, if the conventional normal suspend method is adopted, the suspend process is not performed because only one application did not respond to the suspend, and the other applications that responded to the suspend can not be resumed by the resume process. On the other hand, when the critical suspend method is employed, the suspend process is performed regardless of the state of the application. Therefore, in the application that was in communication, an error occurs even if the resume process is performed, and the subsequent process may not be performed. Therefore, in the present embodiment, the normal suspend method is executed until a sudden system stoppage can occur after a low battery is detected, thereby inquiring each application as to whether or not suspension is possible. Has been reduced, and the process by the critical suspend method is forcibly executed before a situation in which a sudden system stop can occur. Thus, after the resume processing, the system can be returned to a normal state.

Next, the suspending process executed in this embodiment will be described with reference to the flowchart shown in FIG.

The low battery detecting section 2 constantly monitors the power capacity remaining in the battery 1 and sends out a low battery detection signal indicating that the remaining battery capacity has fallen below a certain threshold. The threshold value is set to, for example, about 10% at the time of full charge. When detecting the low-battery detection signal from the low-battery detection unit 2, the timer-interruption generating unit 3 sends out an interrupt signal at regular time intervals, for example, once every 5 seconds. The battery remaining amount warning means constituted by the low battery detection unit 2 and the timer interruption generation unit 3 repeatedly sends an interruption signal at a fixed time interval. When the detection signal is detected, the timer interrupt generation unit 3 may repeatedly transmit the interruption signal, or the low battery detection unit 2 may output the low battery detection signal after the remaining battery power falls below the threshold value. May be transmitted periodically, and the timer interrupt generating unit 3 may transmit an interrupt signal each time the low battery detection signal is detected. In any case, in the present embodiment, after detecting the low battery state, it is not necessary to periodically detect the remaining battery power.

Upon receiving the interrupt signal from the timer interrupt generating unit 3, the suspend process executing unit 4 (step 10).
1) Increment a previously initialized counter (step 102). Here, when the received interrupt signal is the first, the suspend processing execution unit 4 sets an activation prohibition flag for preventing activation of a new application (steps 103 and 104). When receiving a request to start an application, the application execution control unit 5 always refers to the start prohibition flag, and rejects the start request if the start prohibition flag is set. As a result, activation of a new application can be prevented after a low battery is detected. In addition, the suspend processing execution unit 4 notifies the user of the low battery state by displaying a message indicating that a new application cannot be started on the screen (step 105).

By the way, the suspending process executing unit 4 includes:
If the number of forced suspends is set in advance, and if the number of receptions of the interrupt signal has not reached the number of forced suspends (step 106), processing according to the conventional normal suspend method is executed. That is, the suspending process execution unit 4 inquires of each application whether or not suspending is possible (step 107). If all applications respond to this inquiry that suspension is possible, a suspending process, that is, a process of saving the contents of the memory to the disk device or the like is executed (steps 108 and 109). On the other hand, if at least one application does not respond that the suspend is possible, a message such as "Cannot suspend because the application is running. Please terminate the application." Request to terminate the application (step 11
0,111).

On the other hand, when the suspend processing execution unit 4 receives the interrupt signal several times and the counter is incremented, as a result, the number of interrupt signals received reaches the number of forced suspends (step 106). Processing by the suspend method will be executed. That is, the suspend process is executed without inquiring of each application whether the suspend is possible or not (step 109).

As described above, the suspend processing execution unit 4 in the present embodiment performs the normal suspend operation every time it receives an interrupt signal until the number of receptions of the interrupt signal from the timer interrupt generation unit 3 reaches the number of forced suspends. The process according to the method is repeatedly executed (steps 106 to 109), and the process according to the critical suspend method is executed when the number of interrupt signals received reaches the number of times of forced suspension (steps 106 and 109). By providing an unconventional suspend method that appropriately combines the normal suspend method and the critical suspend method,
Not only can the contents of the memory be reliably stored in the disk device, but also the processing executed by the application after the resume processing can be normally resumed.
That is, even if the application is forcibly terminated by the critical suspend method, there are many applications that can resume the process after the resume process without any problem. In addition, when an application is forcibly terminated, there is a possibility that a problem may occur.For example, in an application that is performing communication, the number of reception interrupt signals is reduced because the process being executed is not immediately terminated after detecting a low battery. Until the number of forced suspends is reached, it is necessary to perform some kind of action with the communication partner, such as notifying the normal end of communication or notifying the communication partner of suspension, or preparing to resume processing after resume processing. become able to.

By the way, in order to execute the suspend method in the present embodiment, a threshold value for determining a low battery state and the number of forced suspends must be set in advance. In the present embodiment, it is necessary to set so that the number of interrupt signal receptions reaches the number of forced suspensions while leaving at least enough battery capacity to normally end processing in the critical suspend mode.
That is, the battery capacity at the start of the execution of the process by the critical suspend method is determined, and the set value of each value is determined by a trade-off between the threshold value, the number of forced suspends, and the interrupt signal transmission time interval. For example,
If the remaining battery level at the time of detection of a low battery is small, it is necessary to reduce the number of times of forced suspension or shorten the time interval for transmitting an interrupt signal.

In the present embodiment, it is assumed that the information processing apparatus is provided with a suspend function of both the normal suspend method and the critical suspend method in advance, and that any one of the methods is called as needed. The present embodiment realizes a characteristic suspend method while effectively utilizing the existing suspend method. This reduces the number of newly created parts.
However, when the battery is low, the suspend method provided in the present embodiment is provided to an information processing apparatus equipped with a suspend function that does not employ the conventional two suspend methods or an information processing apparatus not equipped with the suspend function. In order to do this, a suspend method equivalent to the normal suspend method, that is, inquiring about whether or not all the activated applications can be suspended,
A processing function that executes suspend processing only when a response indicating that suspend is possible is received from all applications,
The suspend method corresponding to the critical suspend method, that is, both the processing function of forcibly executing the suspend process without inquiring about whether the suspended application can be suspended or not, is incorporated in the suspend method provided in the present embodiment. It is necessary to be able to selectively execute each processing function (suspend method). The same applies to the embodiments described later.

Embodiment 2 Next, a second embodiment of the information processing apparatus according to the present invention will be described. In the case where the functional block configuration in the present embodiment is shown in FIG.
Is the same as However, the processes of the low battery detection unit 2, the timer interrupt generation unit 3, and the suspend process execution unit 4 in the present embodiment are different from those in the first embodiment, but the details will be clarified in the following description of the process.

The battery remaining amount warning means in the first embodiment sends the same type of interrupt signal after detecting a low battery. Detects an extremely low battery state in which not only the detection of the low battery state but also the suspension processing cannot be postponed any longer, and transmits a different type of interrupt signal according to the detection of the low battery state or the extremely low battery state. It is characterized by doing so. The amount of power consumed is not uniform depending on the number of running applications. Therefore, in Embodiment 1, how many times to set the number of forced suspends is a problem, but in the present embodiment,
Since the execution control of the suspend process is performed based on the remaining battery level, it is possible to reduce the difficulty of setting a value to be set in advance (forcibly suspended battery remaining level).

Next, the suspending process executed in this embodiment will be described with reference to the flowchart shown in FIG. The same processes as those in the first embodiment are denoted by the same reference numerals.

The low battery detection unit 2 constantly monitors the remaining power capacity of the battery 1 and, when detecting that the remaining battery capacity has become equal to or less than a preset suspend start battery remaining capacity, indicates a low battery level indicating that. Transmits a battery detection signal. The suspend start battery remaining amount is, for example, about 10% of a full charge. When detecting the low battery detection signal from the low battery detection unit 2, the timer interrupt generation unit 3
An interrupt signal is transmitted at regular time intervals, for example, once every 5 seconds.
The type of signal transmitted when the suspend start battery remaining amount is detected is a low battery interrupt signal.

When the low battery detection section 2 detects that the remaining battery level being monitored is further reduced and becomes equal to or lower than the forced suspended battery remaining level, the low battery detection signal indicates that the battery level is low. It is sent in place of the embedded signal. The remaining amount of the forced suspend battery is, for example, about 5% of a full charge. However, it is necessary to set the minimum value of the remaining amount of the battery that can execute the process according to the critical suspend method and terminate normally to the remaining amount of the forced suspend battery. Timer interrupt generator 3
Sends an interrupt signal when detecting an extremely low battery detection signal from the low battery detection unit 2. The type of signal transmitted at the time of detection of the remaining amount of the forced suspended battery is an extremely low battery interrupt signal.

Upon receiving the interrupt signal from the timer interrupt generating unit 3, the suspend process executing unit 4 (step 10).
1), the type of the interrupt signal is determined (step 11)
2). If the interrupt signal is a low battery interrupt signal, the counter initialized in advance is incremented (step 102). Since the counter used here is used only for determining whether or not the first low battery interrupt signal is received, a flag may be used. Here, when the interrupt signal received is the first as in the first embodiment, the suspend processing execution unit 4 sets a start prohibition flag for preventing the start of a new application, and starts the new application. An impossibility message is displayed on the screen (steps 103 to 105). After that, the suspend process execution unit 4 executes the process using the normal suspend method as in the first embodiment (steps 107 to 109).
Alternatively, when the received interrupt signal is the first, a message requesting termination of the application is displayed on the screen (steps 110 and 111).

On the other hand, when the interrupt signal received from the timer interrupt generating unit 3 is an extremely low battery interrupt signal, the suspend process executing unit 4 executes a process using the critical suspend method (steps 112 and 109).

According to the present embodiment, when the remaining battery capacity becomes equal to or less than the suspend start battery remaining capacity, the suspend process by the normal suspend method is performed at regular time intervals until the battery remaining capacity becomes equal to or less than the forced suspend battery remaining capacity. The suspend process is executed by the critical suspend method when repeatedly executed and when the battery remaining amount becomes equal to or less than the forced suspend battery remaining amount. Thereby, the same effect as in the first embodiment can be obtained.

Embodiment 3 In each of the above embodiments, the application execution unit 6 that executes an application
Responded promptly to the inquiry about whether or not to suspend from the suspend processing execution unit 4 depending on the state of the application at that time. In the present embodiment, even if the application does not reply to the above inquiry that suspension is possible, if the application has a function of making a transition to a suspendable state by itself, the application can be handled. This processing will be described with reference to the flowchart shown in FIG.

When the battery level warning means detects the low battery state and receives the transmitted interrupt signal (step 101), the suspend processing execution section 4 sends a request to each application included in the processing corresponding to the normal suspend method. An inquiry is made as to whether suspension is possible (step 107). Among the activated applications, those that can be suspended return a response indicating that suspension is possible (step 1).
22, 123). Here, those that are not in a suspendable state transition to a suspendable state by themselves upon receiving the inquiry (step 124). For example,
In the application that was communicating, the communication log is recorded or the communication partner is notified that the application is suspended. Then, when it becomes possible to suspend, a possible flag is set (step 125).

When all applications respond to the above inquiry that all applications can be suspended, the suspend processing unit 4 executes the suspend processing (step 1).
08,109). On the other hand, if at least one application does not reply to the suspend permission, the possible flag is checked (step 113), and when all the applications that did not reply to the suspend permission set the possible flag, the suspend process is executed (step 113). Step 11
4,109). In the window system, the number of running applications can be known, so that the suspend processing execution unit 4 can grasp in advance the number of possible flags to be set. Step 113 to step 11
The processes up to 5 are repeated for a certain period of time until all possible flags to be set are set (step 115).
If the all-possible flag has not yet been set when a certain time has elapsed, a suspend process is executed (step 109).

As is apparent from the above processing, when the suspend processing execution unit 4 receives the interrupt signal from the timer interrupt generation unit 3, the suspend processing execution unit 4 waits for a certain time until the application is in a state in which the application can be suspended. Later, the suspend process will be executed. That is, the battery remaining amount warning means only needs to send the interrupt signal once when detecting the low battery state.

According to the present embodiment, if the application has a function of positively shifting to the suspendable state, the system waits until all the activated applications are in the suspendable state before suspending. Processing can be performed.

In the above description, the suspend process by the critical suspend method is executed after a lapse of a predetermined time. However, the number of repetitions of the processes from step 113 to step 115 is determined by using a count. It may be executed when the number is exceeded. In any case, it must be set so that the execution of the critical suspension method can be started when the remaining battery level is sufficient for normal execution of the suspend processing.

In the above embodiments, a window system providing a normal suspend method and a critical suspend method as suspend functions when the battery is low and a notebook personal computer as an information processing apparatus equipped with a rechargeable battery are assumed. Needless to say, it is not limited to notebook computers.

In recent years, a smart battery system employing an intelligent smart battery has been provided, and this smart battery has a built-in microprocessor in advance. In each of the above embodiments, it is assumed that the function of the battery remaining amount warning means is realized by incorporating a circuit. However, when a smart battery system is mounted on the information processing apparatus, the function of the battery remaining amount warning means is smart. It may be realized by being incorporated in a microprocessor of a battery. Alternatively, only the function of the low battery detection unit 2 of the remaining battery level warning means may be incorporated in the microprocessor.

[0045]

According to the present invention, when the rechargeable battery enters the low battery state, the suspend process is periodically executed by the first suspend method until the number of forced suspends is reached. For the first time, the suspend process according to the second suspend method is forcibly executed, so that the probability of restoring the system in a normal state after the resume process can be further improved.

Further, since a new application is not started after the detection of the low battery state, useless start of the application before execution of the suspend process can be prevented.

Number of executions that counts the number of executions A counting step; forcibly executing the suspend process without inquiring about whether the application is activated when the number of executions counted by the execution number counting step reaches the preset number of forcible suspends. And a second suspend process executing step for executing a suspend process according to a second suspend method. 9. A remaining battery level monitoring step for constantly monitoring the power capacity of a rechargeable battery mounted in the information processing apparatus; and a battery level for monitoring the remaining battery level monitored by the remaining battery level monitoring step. Low battery interrupt signal for a certain period of time until it detects that the battery level has dropped below the battery level, and then detects that the battery level has fallen below the forced suspend battery level that is less than the preset suspend start battery level. A battery remaining amount warning step of repeatedly sending out at intervals and sending an extremely low battery interruption signal after detecting that the battery level has become lower than the forced suspend battery remaining amount, and a low battery interruption sent out by the battery remaining amount warning step Every time a signal is received, all activated applications are inquired about suspendability, A first suspend process executing step of repeatedly executing a suspend process according to a first suspend method that executes a suspend process only when a response indicating that suspend is possible is received from all applications at a fixed time interval; and At the point of receiving the transmitted extremely low battery interrupt signal, executing the suspend process by the second suspend method forcibly executing the suspend process without inquiring of the activated application about whether or not suspend is possible. And a second suspend process execution step. The suspend process method when the battery is low.
