- the BIOS program repeatedly performs the following processing based on the periodic reception of the SMI interrupt request from the IZO controller 1084.
- the device initialization unit 320 When receiving the SMI interrupt request, the device initialization unit 320 notifies the power-off setting unit 210 of the embedded controller 1035 that the BIOS program is operating normally. (S510). Next, the device initialization unit 320 initializes an input / output device managed by the OS, such as the communication interface 1030 or the input device 1032, to release the input / output wait state of the process that cannot be terminated due to the input / output of the input / output device. (S520). More specifically, when a certain input / output device requests the central processing unit 1000 to perform an interrupt process, the device initialization unit 320 may initialize the input / output device. Alternatively, the device initialization unit 320 may initialize all the input / output devices that request the central processing unit 1000 to perform the interrupt processing. As an example, the device initialization unit 320 may perform a process of clearing a key input buffer of a keyboard or the like to initialize a keyboard or a mouse.

For example, the end state setting unit 330 may perform a process for retracting the magnetic surface force of the magnetic head of the hard disk drive 1040.
- the case where the termination program is not operating normally includes the case where a failure has occurred in the operation of the termination program and the case where the processing of the termination program has been completed normally.
- the information processing apparatus 10 can be terminated as safely as possible, not only when the processing of the termination program is normally completed, but also when a failure occurs in the operation of the termination program.
- the BIOS program sends a notification to the Stop processing.
- the embedded controller 1035 turns off the power of the information processing device 10. That is, the power-off setting unit 210 turns off the power of the information processing apparatus 10 when the input / output device is set to the end state by the end state setting unit 330. This can prevent damage to the input / output device, for example, damage to the magnetic surface of the node disk drive.
- FIG. 6 shows an example of an operation flow of an end program operating on the central processing unit 1000.
- the termination processing unit 335 Upon receiving the SCI interrupt request from the IZO controller 1084 based on the instruction from the termination processing instruction unit 300, the termination processing unit 335 displays a screen for inquiring the user whether to terminate the OS (S610). At this time, preferably, the termination processing unit 335 notifies the user that the forced termination processing of the OS has started by displaying to the user a message such as “Start emergency termination processing”. This allows the user to know that the power switch 1038 does not need to be pressed. More preferably, when the user instructs not to terminate the OS, the termination processing unit 335 notifies the user that the OS cannot be continuously used normally. Further, the termination processing unit 335 may notify the user that the process and the OS should be manually terminated, the OS should be restarted, and the use of the OS should be resumed. Then, the end program repeats the following processing.
- the termination processing unit 335 notifies the BIOS program that the termination program is operating normally (S620). Then, the termination processing unit 335 determines whether or not the inquiry of the IJ user in S610 has timed out, that is, inquires of the user whether or not the ability to terminate the OS in S610, and determines whether or not the power has passed the predetermined time. (S630). When a timeout occurs (S630: YES), the termination processing unit 335 shifts the processing to S655.
- the termination processing unit 335 determines whether or not the user received an operation in response to the inquiry (S640). If no operation has been received (S640: NO), the termination processing unit 335 returns the processing to S620. When an operation is received (S640: YES), the termination processing unit 335 determines whether or not the operation is an instruction to terminate the OS (S650).
- the termination processing unit 335 periodically notifies the BIOS program that the termination program is operating normally (S652). This As a result, if the input / output device has been initialized by the device initialization unit 320 and the OS has not been terminated yet, and the OS has resumed operation, the termination processing unit 335 provides the user with the use of the OS. Can be continued. As a result, the user cannot use the OS in a normal state, but can manually terminate the OS after properly saving the data of the application program as necessary.
- the termination processing unit 335 transmits a termination instruction to the OS (S655). Then, the termination processing unit 335 notifies the BIOS program that the termination program is operating normally (S660). Then, the termination processing unit 335 acquires a list of processes operating on the OS from the OS, and transmits a termination instruction to these processes (S670). The termination processing unit 335 repeats the processing of S660 and S670.
- the processing in the figure may be realized as one function of the operating system instead of the end program. That is, the termination processing instruction unit 300 may request the OS to terminate the process, and then terminate the OS. In this case, depending on the type of failure that occurs in the operating system, the termination process may not be performed properly, but the efficiency is high because it is not necessary to make the termination program resident in the operating system.
- the information processing apparatus 10 causes the BIOS program to transmit an end instruction for terminating the process to the OS process, and the process that cannot be terminated due to waiting for input / output of an input / output device. Initialize the I / O devices that should release the I / O wait state. As a result, the hung OS can be returned to a normal state and terminated normally.
- the information processing apparatus 10 can switch the processing when the power is turned off in accordance with how the power switch is operated. This allows the user to select the process of turning off the power even when a failure that disables operation with the keyboard or the like occurs. Further, the information processing apparatus 10 saves the termination status when the power is turned off, and displays it at the next startup. This makes it easier to find the cause of the obstacle.
