휴대용 컴퓨터 및 그 전원제어방법{portable computer and power controlling method thereof}Portable computer and power controlling method

본 발명은 휴대용 컴퓨터에 관한 것으로서, 보다 상세하게는 전원소비를 감소시킬 수 있는 휴대용 컴퓨터에 관한 것이다.The present invention relates to a portable computer, and more particularly, to a portable computer that can reduce power consumption.

휴대용 컴퓨터는 데스크탑 컴퓨터에 비해 부피가 작고 이동성이 뛰어나 외부활동이 잦은 사용자에게 널리 사용되고 있다.Portable computers are widely used for users who have a lot of external activities because they are smaller and more mobile than desktop computers.

일반적으로, 휴대용 컴퓨터는 하드디스크 및 메모리 등의 하드웨어장치와 마이컴(micro processor)으로 구성된 시스템이 마련된 컴퓨터본체와, 컴퓨터본체와 힌지결합하여 화상을 표시하는 디스플레이부와, 시스템과 디스플레이부에 전원을 공급하는 전원공급부를 갖는다.In general, a portable computer includes a computer main body provided with a system consisting of a hardware device such as a hard disk and a memory and a microprocessor, a display unit hinge-coupled with the computer main body to display an image, and a power supply to the system and the display unit. It has a power supply for supplying.

이러한 휴대용 컴퓨터는 직류전원용 어댑터에 의해 전원을 공급받거나, 전기가 공급되지 않는 장소에서의 사용을 고려하여 밧데리를 부착하여 밧데리전원에 의해 사용할 수 있게 되어 있다. 그러나, 밧데리전원에 의해 휴대용 컴퓨터를 사용할 경우, 밧데리의 충전용량이 작아 컴퓨터를 사용할 수 있는 시간이 제한되어 있다. 이에 따라, 휴대용 컴퓨터의 전원소비를 줄이기 위해 하드웨어 또는 소프트웨어적으로 다양한 전원관리방법이 제안되고 있다.Such a portable computer can be used by a battery power source by attaching a battery in consideration of use in a place where power is supplied by a DC power adapter or a place where electricity is not supplied. However, when the portable computer is used by the battery power source, the charging capacity of the battery is small and the time for which the computer can be used is limited. Accordingly, various power management methods have been proposed in hardware or software to reduce power consumption of portable computers.

그런데, 컴퓨터본체 일측의 전원스위치의 선택시, 턴온되는 전원스위치표시LED와 하드디스크등의 동작표시용 LED는 컴퓨터시스템이 동작 중일 때, 사용자가 LED를 거의 확인하지 않으므로 불필요한 전원이 소비된다.However, when the power switch of one side of the computer main body is selected, the power switch display LED and the operation display LED such as the hard disk that are turned on consume little power because the user hardly checks the LED when the computer system is in operation.

따라서, 본 발명의 목적은, 컴퓨터의 동작 중에는 전원공급표시부로의 전원공급을 차단하여 전원소비를 감소시킬 수 있는 휴대용 컴퓨터를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a portable computer which can reduce power consumption by cutting off the power supply to the power supply display unit during the operation of the computer.

Can be reduced.

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 컴퓨터의 사시도이다. 도면에 도시된 바와 같이, 휴대용 컴퓨터(1)는 LCD패널이 부착된 디스플레이부(2)와, 디스플레이부(2)에 힌지 결합되는 컴퓨터본체(3)를 갖는다. 컴퓨터본체(3) 상부면의 일측에는 디스플레이부(2)의 개방 또는 닫힌 상태를 감지하는 개폐감지부(9)가 돌출형성되어 있으며, 컴퓨터본체(3)의 좌측에는 전원스위치(5)와, 본 발명에 의해 디스플레이부(2)의 개폐에 따라 온오프되는 전원공급표시부(7)가 마련되어 있다.1 is a perspective view of a computer according to the present invention. As shown in the figure, the portable computer 1 has a display portion 2 with an LCD panel attached thereto and a computer body 3 hinged to the display portion 2. On one side of the upper surface of the computer main body 3, the opening and closing detection unit 9 for detecting the open or closed state of the display unit 2 is protruded, and the power switch 5 and the left side of the computer main body 3, According to the present invention, there is provided a power supply display portion 7 which is turned on and off in accordance with the opening and closing of the display portion 2.

도시 않은 컴퓨터본체 (3)내에는 밧데리 또는 어댑터에 의해 전원을 공급하는 전원공급부와, 밧데리 또는 어댑터의 전원공급부로부터 공급되는 전원을 정상모드 또는 대기모드의 상태에 따라 각 하드웨어장치로 공급되도록 제어하는 마이컴이 마련되어 있다. 여기서, 개폐감지부(9)는 가압시 마이컴(15)과 연결된 전기선이 접촉되어 전기신호를 발생하는 스위치로 구성할 수 있다.In the computer main body 3, not shown, a power supply unit for supplying power by a battery or an adapter and a power supply unit for supplying power from the battery or adapter power supply unit are supplied to each hardware device according to a normal mode or a standby mode. Microcomputer is provided. Here, the opening and closing detection unit 9 may be configured as a switch for generating an electrical signal by contacting the electric line connected to the microcomputer 15 when the pressure.

도 2는 도 1의 휴대용 컴퓨터의 제어블럭도이다. 도면에 도시된 바와 같이.마이컴(15)은 전원스위치(5)가 온(ON)된 후, 소정 시간이 경과되면 전원공급부(6)에 제어신호를 인가하여 전원공급표시부(7)로 공급되는 전원을 차단한다. 여기서, 마이컴(15)의 전원공급표시부(7)로의 공급전원을 차단하는 시간은 컴퓨터의 부팅시 키보드의 'DEL' 키를 선택하여 표시되는 바이오스(BIOS)셋업프로그램에서 설정하도록 프로그램화할 수 있다.FIG. 2 is a control block diagram of the portable computer of FIG. 1. As shown in the figure. The microcomputer 15 is supplied to the power supply display unit 7 by applying a control signal to the power supply unit 6 after a predetermined time elapses after the power switch 5 is turned on. Shut off the power. Here, the time to cut off the power supply to the power supply display unit 7 of the microcomputer 15 may be programmed to be set in the BIOS setup program displayed by selecting the 'DEL' key of the keyboard when the computer boots.

마이컴(15)은 개폐감지부(9)에서 발생되는 전기신호에 기초하여 디스플레이부(2)가 개방상태인 경우, 전원공급표시부(7)에 전원을 공급하고, 디스플레이부(2)가 닫힌 상태인 경우, 전원공급표시부(7)로의 전원공급을 차단한다.The microcomputer 15 supplies power to the power supply display unit 7 when the display unit 2 is open based on the electrical signal generated by the open / close detection unit 9, and the display unit 2 is closed. In this case, the power supply to the power supply display section 7 is cut off.

도 3은 본 발명에 따른 휴대용 컴퓨터의 제어순서도이다. 도면에 도시된 바와 같이, 밧데리에 의한 전원이 공급될 때(S1), 디스플레이부가 개방 또는 폐쇄상태인지를 판단하여(S3), 디스플레이부가 개방상태인 경우, 전원공급표시부를 턴온시킨다(S4). 사용자가 전원스위치를 온시켜(S5), 시스템이 동작된 후 소정 시간이 경과되었는 지를 판단하여(S6), 소정 시간이 경과된 경우 전원공급표시부를 턴오프시킨다(S7). 한편, 소정 시간이 경과되기 전에 컴퓨터가 대기모드로 진입할 경우(S8) 또는 디스플레이부가 닫히는 경우 전원공급표시부를 턴오프시킨다(S9).3 is a control flowchart of a portable computer according to the present invention. As shown in the figure, when power is supplied from the battery (S1), it is determined whether the display unit is in an open or closed state (S3), and when the display unit is in an open state, the power supply display unit is turned on (S4). The user turns on the power switch (S5), determines whether a predetermined time has elapsed since the system is operated (S6), and turns off the power supply display unit (S7) when the predetermined time has elapsed. On the other hand, when the computer enters the standby mode before the predetermined time elapses (S8) or when the display unit is closed, the power supply display unit is turned off (S9).

도 4는 본 발명의 다른 실시예에 따른 휴대용 컴퓨터의 제어순서도이다. 도 4는 어댑터에 의한 전원이 공급되는 경우(P1), 먼저 전원공급표시부를 턴온시킨다(P3). 사용자가 전원스위치를 온시켜(P4), 소정 시간이 경과된 경우 전원공급표시부를 턴온시킨다(P5). 한편, 소정 시간이 경과되기 전에 컴퓨터가 대기모드로 진입할 경우(P6) 또는 디스플레이부가 닫히는 경우(P7) 전원공급표시부를 턴오프시킨다(P9).4 is a control flowchart of a portable computer according to another embodiment of the present invention. 4, when power is supplied by the adapter (P1), first turn on the power supply display (P3). The user turns on the power switch (P4), and turns on the power supply display unit (P5) when a predetermined time has elapsed. On the other hand, when the computer enters the standby mode before the predetermined time elapses (P6) or when the display unit is closed (P7), the power supply display unit is turned off (P9).

여기서, 전술한 실시예에서는 전원스위치의 전원공급표시부로 한정하여 서술하였으나, 본 발명은 전원스위치이외에도 하드디스크 또는 기타 하드웨어상태표시부에도 적용할 수 있다.Here, in the above-described embodiment, the power supply display unit of the power switch has been described. However, the present invention can be applied to a hard disk or other hardware state display unit in addition to the power switch.

또한, 실시예에서는 컴퓨터가 정상모드에서 대기모드상태로 변환될 때, 전원스위치가 오프되는 것으로 서술하였으나, 사용자가 대기모드인식이 용이하도록 대기모드 상태에서는 전원스위치가 오프되지 않도록 마이컴설정을 조정할 수 있음은 물론이다.In addition, although the embodiment described the power switch to be turned off when the computer is switched from the normal mode to the standby mode, the microcomputer setting may be adjusted so that the power switch is not turned off in the standby mode so that the user can easily recognize the standby mode. Of course.

이러한 구성에 의하여, 휴대용 컴퓨터가 동작중일 때, 전원스위치 표시용LED를 턴오프시켜 전원소비를 감소시킬 수 있다. 한편, 전원스위치를 선택하지 않아도 디스플레이부의 개방시 전원공급표시 LED가 턴온되므로, 어두운 장소에서 전원스위치를 용이하게 선택할 수 있다.By such a configuration, power consumption can be reduced by turning off the power switch display LED when the portable computer is in operation. On the other hand, even when the power switch is not selected, the power supply display LED is turned on when the display unit is opened, so that the power switch can be easily selected in a dark place.

이상 설명한 바와 같이, 본 발명에 따르면, 컴퓨터의 동작 중에는 전원공급표시부로의 전원공급을 차단하여 전원소비를 감소시킬 수 있는 휴대용 컴퓨터가 제공된다.As described above, according to the present invention, a portable computer capable of reducing power consumption by cutting off power supply to the power supply display unit during operation of the computer is provided.
