BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a green computer, and in particular, it is easy to save data using a DC power supply, and to extract data from a disk saved during power-off during rebooting. It's about a fast boot device on a green computer that you want to boot from.

Normally, a green computer has a hibernation function, which is equipped with a battery module (that is, a DC to Dc converter, charge logic, and a battery) in a system to perform a save to disk during a power failure. After the reboot, the data was fetched from the disk to enable fast booting.

When you save off the power supply, the above-mentioned save to disk saves the current working environment and data to the hard disk (HDD) as it is. It is a program that can shorten booting time by extracting data from hard disk without going through Self Test step.

However, the conventional hibernation function has a great advantage in the case of power failure or high speed booting, while there is a problem in that the cost is increased by lowering the cost by applying the battery module.

In addition, most of the power supply applied to the personal computer power supply is cut off immediately when the switch off, there was also a problem that you can not use the save-to-disk without using the battery.

Therefore, the present invention is to solve the above-mentioned problems of the prior art, an object of the present invention is to easily save and reboot the data using a DC switch power supply (DC Switch Power Supply) (Rebooting) The present invention provides a fast booting device of a green computer that allows a high speed booting operation by extracting data from a saved disk at power off.

The technical means for achieving the object of the present invention is to output a state signal from low to high when the power-off signal is input in response to the contact of the DC switch and output the save-to-disk completion signal from the system controller to low When the power supply is turned on, the power supply turns off the power, and when the status signal obtained from the power supply is applied to the high, the save-to-disk completion signal is output to the power supply. And the power supply to turn off the power by setting the save-to-disk completion signal low.

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

FIG. 1 is a block diagram of a fast boot device of a green computer according to the present invention. As shown in FIG. 1, when a power off signal is input in response to a contact of a DC switch, a status signal transitions from low to high and is output. When the save-to-disk completion signal (AK / OFF signal) is input low from the system controller 20, the power supply 10 for turning off the power and the status signal obtained from the power supply 10 are high. When it is applied to the save to disk completion signal (AF / OFF Singnal) high to the power supply (10), and executes the save to disk, when the save to disk is completed, the save to disk completion signal (AK / OFF It is configured as a system controller 20 for outputting the signal low to enable the power supply 10 to turn off the power.

The operation and effects of the fast booting apparatus of the present invention constructed as described above will be described with reference to FIG. 2.

First, the DC switch power supply employed in the present invention has a mechanical device different from that of an AC power supply used in a conventional computer. Existing AC power supply device is composed of a device that receives AC power until the switch is turned off and makes DC power (+ 5V, + 12V, -5V, -2V, etc.) used in the computer until the switch is turned off.

We used a special DC switch power supply for the save-to-disk.

This is the same as making a DC power by receiving the existing AC power, but this DC power is made possible by using a simple logic circuit. Therefore, a simple circuit can control the DC power supply to the entire system.

The switch power supply not only supplies conventional DC power, but also has the ability to control special signals.

In other words, when the DC power switch is pressed once, an arbitrary signal is supplied to the power supply to generate a status signal in order to proceed with the save-to-disk.

The system controller then generates a save-to-disk completion signal (AK / OFF signal), and this signal is supplied to the DC switch power supply and DC power supply with a logic circuit to turn off the powder after a certain time. Device.

Under this background, when one-touch of the DC switch to turn off the power when the power is on (ON) as shown in FIG. 1, the power supply 10 does not immediately turn off the power. Instead, as shown in FIG. 2, a state signal (ie, a signal for power off) is transitioned from low to high and input to the system controller 20 existing on the motherboard.

Accordingly, when the state signal is input high, the system controller 20 sets the save-to-disk completion signal (AK / OFF signal) as high as the hatched portion of (b) shown in FIG. Input to a power supply (10) and the SMI (System Management Interrupt) to run a save-to-disk.

Thereafter, when the save-to-disk is completed, the save-to-disk completion signal (AK / OFF signal) is transferred to a low signal and input to the power supply 10.

Accordingly, the power supply 10 determines that the save-to-disk is completed when the input of the save-to-disk completion signal as described above is to turn off the power.

If, after applying the status signal to the high system controller 20 in the power supply 10, the save-to-disk completion signal is not inputted high due to an abnormal operation of the system, the power supply 10 causes the high power transition to the high. The power is automatically turned off when the status signal transitions low.

As described in detail above, the present invention utilizes a DC switch power supply to easily save current data on the hard disk during power-off, and immediately retrieve the data stored on the hard disk without going through the POST step upon reboot. By doing so, the booting time can be shortened. In addition, since a battery module that is separately installed to execute the save-to-disk is not required as in the related art, the cost can be lowered and the economical efficiency can be improved.
