Description

Portable computer and indicating method of portable computer

The present invention relates to a portable computer and a display method of the portable computer.

As shown in FIG. 7, a conventional portable computer includes a main body housing 120 forming an exterior, a central processing unit 125 and a main board 130 provided in the main body housing 120 to drive an application program. And a hard disk drive (not shown) capable of storing and reading application programs, a cooling fan 170 for dissipating the CPU 125, a display device 140, and an input device 150. In addition, a temperature chip set 132 provided on the main board 130 to sense the temperature of the central processing unit 125, and a control unit (not shown) for controlling the system in accordance with the temperature detection result of the temperature chipset 132 Include.

The system temperature control method in the conventional portable computer having the above configuration is as follows.

8 is a system temperature control flowchart of a conventional portable computer.

First, a manufacturer or a user of a portable computer may be provided with a cooling start temperature driven by a cooling fan, an overtemperature temperature for decelerating the internal clock of the central processing unit 125, and a temperature at which the central processing unit 125 cannot operate normally. The system stops and saves the work in progress on the hard disk drive (not shown) and sets the stop temperature to shut down the system.

When the user applies power to the system to perform a task using the portable computer, the temperature of the central processing unit 125 is gradually raised (P10). Accordingly, the temperature chipset 132 provided on the main board 130 generates a signal from time to time while driving the system to detect the temperature of the central processing unit 125. Here, when the temperature of the central processing unit 125 reaches the cooling start temperature at which the temperature is to be lowered by driving the cooling fan 170, the temperature chipset 132 generates an interrupt (P20). Thus, the controller (not shown) drives the cooling fan 170 to cool the temperature of the central processing unit 125 (P30).

When the temperature of the central processing unit 125 is lowered by the driving of the cooling fan 170, the temperature chipset 132 generates an interrupt again, and the controller stops driving the cooling fan 170 (P45 and P47). . However, as a result of sensing the temperature of the temperature chipset 132, despite the driving of the cooling fan 170, the temperature of the central processing unit 125 does not decrease, but rather, the temperature rises and the internal clock of the central processing unit 125 is increased. When the temperature reaches the state of the overheated temperature at which the temperature of the central processing unit 125 is to be decreased, the temperature chipset 132 generates an interrupt again (P40).

Therefore, the controller decelerates the internal clock of the CPU 125 (P50). The central processing unit 125 has a temperature drop in accordance with the cooling fan 170 and the internal clock deceleration of the central processing unit 125. Here, when the temperature of the central processing unit 125 drops below the over temperature due to the internal clock deceleration of the cooling fan 170 and the central processing unit 125, the temperature chipset 132 generates an interrupt, and the controller The internal clock of the CPU 125 is returned to normal based on the interrupt of the temperature chipset 132 (P65 and P67).

However, even if the cooling fan 170 and the internal clock of the central processing unit 132 are decelerated, the temperature of the central processing unit 125 does not drop below the over temperature, but the central processing unit 125 may operate normally. When the uninterrupted stop temperature is reached, the temperature chipset 132 again generates an interrupt (P60). Accordingly, the controller (not shown) stores the work being performed on the hard disk drive (not shown) and terminates the system (P70).

However, such a system temperature control method of a conventional portable computer, the system is controlled in a state that the user does not recognize. Therefore, suddenly the internal clock deceleration of the central processing unit, the performance of the system is significantly reduced, or the system is powered off when the temperature of the central processing unit reaches the stop temperature, the situation occurred in the situation that the user does not recognize, The user may be dissatisfied with the system or lose the trust of the system.

Therefore, it is necessary to find a way to improve the reliability of the system by making the user aware of the current system state.

Accordingly, an object of the present invention is to provide a portable computer and a display method of the portable computer that can improve the reliability of the system by making the user aware of the current system state.

Here, when the detection temperature exceeds a predetermined cooling start temperature, the control unit indicates that the cooling start temperature is exceeded and drives the cooling fan. It is effective because it can recognize that the temperature to be driven has been reached.

The controller may indicate that the overtemperature temperature has been exceeded on the display unit when the detected temperature exceeds a predetermined overtemperature temperature, and decelerate an internal clock of the central processing unit. It is preferable to not only drive a cooling fan to cool the temperature of the CPU beyond the temperature, but also to allow the user to recognize that the internal clock of the CPU is decelerated.

When the detected temperature exceeds a predetermined stop temperature, the controller indicates that the stop temperature has been exceeded on the display unit, and saves the contents of the work being performed on the hard disk drive and terminates the system. Since the temperature of the processing device exceeds the stop temperature and reaches the state in which the central processing device can no longer be driven, it is effective to save the work being performed and to recognize that the system is being shut down.

The display unit may be any one of at least one LED, a display program for displaying a text message on the monitor, and a buzzer for generating an alarm sound, so that the present system can be effectively displayed to the user.

The temperature sensing unit is preferably a temperature chipset provided on the main board so as to effectively sense the temperature of the central processing unit.

On the other hand, the above object, according to another field of the invention, in the display method of a portable computer having a central processing unit, a hard disk drive and a monitor cooled by a cooling fan, the step of sensing the temperature of the central processing unit ; Based on the detection result, when the detected temperature exceeds a predetermined set temperature, it may be achieved by a display method of a portable computer, comprising the step of indicating that the set temperature is exceeded.

In the detecting of the temperature, when the detected temperature exceeds a predetermined cooling start temperature, the display unit indicates that the cooling start temperature is exceeded and includes driving the cooling fan. It is desirable to cool the temperature of the central processing unit and to inform the user of the current system status.

In the detecting of the temperature, when the detected temperature exceeds a predetermined overtemperature temperature, the display indicates that the overtemperature temperature has been exceeded, and decelerates an internal clock of the central processing unit. It slows down the internal clock and lowers the temperature of the central processing unit. It is effective to let the user know the current system status.

In the detecting of the temperature, when the detected temperature exceeds a predetermined stop temperature, the display unit indicates that the stop temperature has been exceeded, and saves and terminates the work being performed on the hard disk drive. It is desirable to be able to tell the status of the current system.

In the display step, it is preferable that any one of a display program for turning on an LED, a buzzer for generating a warning sound, and a display program for displaying a text message on the monitor can effectively display the state of the system to the user.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a portable computer according to the present invention, Figure 2 is an exploded perspective view of a portable computer according to the present invention, Figure 3 is an enlarged exploded perspective view of the main portion of FIG. As shown in these figures, the configuration of the portable computer according to the present invention is installed to be folded or unfolded with respect to the computer main body 10 and the computer main body 10 in which a plurality of hardware, including the central processing unit 25 is embedded. And a display device 40 and an input device 50 for outputting information input according to a user's operation, and a cooling fan 70 for cooling the heat generated by the central processing unit 25. In addition, a message is output to the display unit 80 based on the temperature chipset 32 for sensing the temperature of the central processing unit 25, the display unit 80 for outputting a message, and the sensed temperature of the temperature chipset 32. It includes a control unit 90 to.

The computer main body 10 is mounted on the main board 30, the main board 30 accommodated in the main body 20, and the main board 30 to form the appearance of the computer main body 10, the application program And a plurality of hardware, including a central processing unit 25 to perform, and a hard disk drive 60 capable of storing and reading application programs.

The cooling fan 70 is provided at a position adjacent to the central processing unit 25 in the body housing 20 to cool the central processing unit 25. As shown in FIG. 3, the CPU 25 and the cooling fan 70 are coupled to the heat sink 72. In general, the heat sink 72 is made of a material having high thermal conductivity. Accordingly, the cooling fan 70 does not directly cool the central processing unit 25, but rather cools the adjacent heat sinks 72, and the heat sink 72 again cools the central processing unit 25.

Meanwhile, the temperature chipset 32 is provided in the main board 30. The temperature chipset 32 senses the temperature of the central processing unit 25 while the central processing unit 25 is being driven. As a result of the temperature sensing of the temperature chipset 32, when the temperature exceeds the initial set temperature of the system, the temperature chipset 32 generates an interrupt to suspend the system and calls the controller 90 to be described later.

The display unit 80 is three LEDs 82 provided on the upper surface of the main body housing 20. The LED 82 displays the state of the current system to the user under the control of the controller 90 which is driven by the interrupt of the temperature chipset 32. At the bottom of the three LEDs 82, messages such as cooling start temperature, over temperature, and stop temperature are printed so that the user can easily recognize the state of the system when the LED 82 is turned on.

The control unit 90 is a control program that is driven in accordance with the occurrence of the interrupt of the temperature chipset 32. When the temperature chip set 32 senses the temperature of the central processing unit 25 and exceeds a predetermined set temperature, it is called according to an interrupt generated to perform a preset task.

The predetermined set temperature is preset by the manufacturer of the portable computer or set by the user. The manufacturer or user has reached a cooling start temperature driven by the cooling fan 70, an over temperature to slow down the internal clock of the central processing unit 25, and a temperature at which the central processing unit 25 cannot operate normally. By doing so, the contents of the work being performed are stored in the hard disk drive 60 and the stop temperature for terminating the system is set in the system.

Therefore, the controller 90 cools the display unit 80 based on the interrupt generated by the temperature chipset 32 when the temperature of the temperature processor 32 exceeds the cooling start temperature as a result of sensing the temperature of the central processing unit 25. It outputs that the start temperature has been reached and drives the cooling fan 70 on the main board 30 to cool the central processing unit 25.

In addition, when the temperature of the CPU 25 exceeds the second set temperature, the controller outputs that the over temperature has been reached on the display 80, and decelerates the internal clock to the CPU 25. Let's go. Accordingly, the central processing unit 25 decelerates the internal clock to lower the temperature of the central processing unit 25.

However, even when the internal clock is decelerated in the cooling fan 70 and the central processing unit 25, the temperature of the central processing unit 25 does not fall below the over temperature, but the central processing unit 25 performs its normal duties. When the stop temperature is reached, the controller 90 outputs to the display unit 80 that the stop temperature has been reached. In addition, the user is provided with a time to store the contents of the work being performed on the hard disk drive 60, and if the storage time is exceeded, the contents of the work being performed are stored on the hard disk drive 60 and the system is terminated.

According to the above configuration, the display method of the portable computer according to the present invention will be described.

5 is a system control flowchart of a portable computer according to the present invention.

The user applies power to the system to perform a task using a portable computer (S10). As the portable computer is used, the temperature of the central processing unit 25 gradually rises.

Temperature chipset 32 generates a signal from time to time during the operation of the system to detect the temperature of the central processing unit 25, the cooling start temperature to drive the cooling fan 70 to lower the temperature of the central processing unit 25 When it reaches to generate an interrupt (S20). The controller 90 lights the first LED 82 provided on the upper surface of the main body housing 20 as shown in FIG. 4 based on the interrupt of the temperature chipset 32. In addition, the controller 90 drives the cooling fan 70 to lower the temperature of the CPU 25 (S30). Here, when the temperature of the central processing unit 25 is located between the cooling start temperature and the over temperature, the controller 90 continues to drive the cooling fan 70 to cool the temperature of the central processing unit 25 (S45). ).

In addition, when the temperature of the central processing unit 25 decreases due to the operation of the cooling fan 70, the temperature chipset 32 generates an interrupt again, and the controller 90 controls the cooling fan 70 based on the interrupt. Emphasis is placed on driving (S47).

However, as a result of sensing the temperature of the temperature chipset 32, despite the driving of the cooling fan 70, the temperature of the central processing unit 25 does not decrease, but rather, the temperature rises and the internal clock of the central processing unit 25 is increased. When the overtemperature state is reached, the temperature chipset 32 generates an interrupt again (S40). Accordingly, the controller 90 also turns on the second LED 82 provided on the upper surface of the main body housing 20. In addition, the controller 90 decelerates the internal clock in the CPU 25 (S50).

Accordingly, the central processing unit 25 is lowered in temperature with the cooling fan 70 and the internal clock deceleration of the central processing unit 25. Subsequently, when the temperature of the central processing unit 25 is located between the stop temperature and the over temperature, the control unit 90 decelerates the internal clock of the cooling fan 70 and the central processing unit 25 to continuously control the central processing unit. The temperature of 25 is cooled (S60, S65).

When the temperature of the central processing unit 25 drops below the over temperature due to the internal clock deceleration of the cooling fan 70 and the central processing unit 25, the temperature chipset 32 generates an interrupt again, and the controller 90 ) Returns the internal clock of the central processing unit 25 to the normal state based on the interrupt (S67). In addition, when the temperature sensing result of the temperature chipset 32 is lowered below the cooling start temperature, the controller 90 stops the cooling fan 70 again and turns off the corresponding LED 82. Here, when the temperature of the central processing unit 25 is located between the overtemperature temperature and the cooling start temperature, the corresponding LED 82 is turned on and the cooling fan 70 is driven (S45 and S47).

However, even when the internal clocks of the cooling fan 70 and the central processing unit 25 are decelerated, the temperature of the central processing unit 25 may not be cooled below the over temperature, but the central processing unit 25 may operate normally. When the stop temperature is reached, the temperature chipset 32 again generates an interrupt.

Accordingly, the control unit 90 also turns on the third LED 82 of the main body housing 20 to inform the user that the state of the current CPU 25 has reached a state in which it cannot operate normally. Accordingly, the user may save the work contents which are being performed as a follow-up action to the hard disk drive 60 and shut down the system. However, if the user fails to save the work contents on the hard disk drive 60, the controller 90 stores the work contents being performed on the hard disk drive 90 and terminates the system (S70).

On the other hand, Figure 6 is a screen configuration of a portable computer according to a second embodiment of the present invention, having the same components as the above-described portable computer, the display unit 80 is provided as an LED 82 on the body housing 20 Instead, the display program 85 outputs a text message on the display device 40. The display program 85 displays the current system status to the user in a text message that the control unit 90 outputs on the display device 40 in response to the interruption of the temperature chipset 32. As shown in FIG. 6, the text message output from the display program 85 displays a window of which state the system has reached. Accordingly, the user is provided with the state of the current system from the display program 85 to recognize the state of the system, thereby enabling the user to trust the system.

In the above-described and embodiments, three LEDs 82 are used to indicate the state of the system. However, even one LED may be used to achieve the object of the present invention. In the case of using one LED, two LED chips emitting different colors are prepared in the LED. At the cooling start temperature, it emits one LED chip in the LED to output the current system status to the user. At the over temperature, the LED chip emits another color. In addition, at the last stop temperature, two LED chips emit light simultaneously to emit a third color, so that the user can recognize the current system state. In addition to this method, the object of the present invention can be achieved by providing only one LED as a method of adjusting the lighting interval.

Although the display unit 80 has been described as displaying the state of the system by the LED 82 or the display program 85 in the foregoing and embodiments, it is possible to achieve the object of the present invention to provide a buzzer for generating a warning sound. Can be.

In addition, in the above-described embodiments, the temperature of the central processing unit 25 is sensed by the temperature chipset 32 provided on the main board 30. However, in addition to the temperature chipset 32, a temperature sensor or the like may be provided. Of course, the temperature of the central processing unit 25 can be sensed.

In this way, the temperature chip set for sensing the temperature of the central processing unit, the display unit for outputting a warning message, and the control unit that interlocks based on the occurrence of the interrupt of the temperature chip set make the user aware of the current system state. Provided are a portable computer and a display method of the portable computer which can improve the reliability.
