Description of the Invention: [Technical Field] The present invention relates to a power management method, and more particularly to a power management method for an optical disk drive. [Previous technology #ί] In order to reduce the energy consumption of the electronic device, the manufacturer usually designs a power management method for the electric device, so that the electronic device enters a sleep state when not in use to reduce Energy loss. Figure 1 shows the traditional multimedia command (Multimedia Commands MMC) protocol, which can be used as a power management method for a CD player. According to a conventional multimedia command protocol, the optical disk drive is in an idle state 102, a standby state 104, a sleep state 106, an active state 108, and a close (0ff) state. Switch between 11〇. Conventional multimedia command protocol switching conditions include: hard weight or media not ready 112, media insertion 114 and 116, idle command 118, standby command (standby command) 120, media access instructions (mediaaccess) 122 and 124, idle timer expires or idle command (lid timer expires or idle command) l26, standby timer time or standby command (standby timer expires or standby command 28) Device reset 130, powerremoved 132, and sleep commands 134, 136, and 138. As shown in Fig. 1, the optical disk drive switches to the idle state lQ2 and the use state (10) only when a sleep command 134, 136, or 0535-A21539TWF(N2); A05138; Glorious_Jjen 200805257 138 occurs. Sleep state 106. Therefore, under the traditional multi-body command protocol architecture, unless the hibernation command 134, 136, or 138 occurs, the optical disk drive is still unable to switch to the sleep state even if the optical disk drive has not been used for a long time. The invention provides a power management method for switching an optical disk drive that has not been used for a long time to a sleep state, and (4) more energy. The power management method provided by the present invention includes a dish-in state of a disc player, no disc on the disc, and the disc 2 is maintained in an idle state or a standby state for more than a period of time. And switching the optical disk drive to the -sleep state; and when the disk of the optical disk drive is in an exit state (tmy-〇Ut), and the optical disk drive is maintained in the idle state or the standby state exceeds a period of time] Switch the disc drive to the sleep state. The method for the power supply method to jump out of the sleep state may include: when the CD player is in the sleep state, and the disk is switched between the income state and the exit state, the CD player is caused to exit the sleep state. And switch to the standby state. The disc can be switched between the revenue status and the exit status by pressing a push-back button (7). The disc can also be pushed into the disc by an external force to switch the disc from the exit state to the revenue state. The power management method may further include: when the optical disk drive is in the dormant state, an automatic response module (aut〇-reSp〇nse is used to replace the optical disk drive in response to an operating system to be issued to the optical disk drive) a non-media access command 0535-A21539TWF(N2); A05138; Gk>ri〇us Jien 6 200805257 command) to maintain the disc player in the dormant state (non-media access state. The disc player is in the sleep state) When the operating system times out a media access command issued by the operating system, the operating system issues a soft weight command to the optical disk drive (s〇ft reset c〇mmand) In order to switch the disc drive to the standby state. The power management method may further include other rules, some of which are in compliance with the Multimedia Commends (MMC) protocol.

Therefore, the optical disk drive is not affected by the non-media access command and can be maintained in the sleep state 21 〇 to reduce unnecessary energy loss. This paragraph describes other rules of the power management method described in Figure 2. The disc player does not respond to a media access command issued by the operating system to the disc in the sleep state 210. Therefore, the media access command will be timeout. At this time, the operating system releases a soft reset command to the optical disk drive to switch the optical disk drive to the standby state 208. 0535~A21 539TWF(N2);A05138;Glorious_Tien 9 200805257 With the first picture, the power management method shown in Figure 2 includes other rules, some of which follow a multimedia command (Multmiedia Commends, MMc) Agreement (ie, the shape diagram shown in Figure j). " Fig. 3 is a computer system 300 proposed by the present invention for implementing the power management method of the present invention. The computer system 300 will be explained below in conjunction with the power management method shown in FIG. The computer system 3 is operable in a use state 212, an idle state 206, a standby state 2〇1, and a sleep state 210. The control unit 3〇4 of the computer system detects the disc when it is determined that the disc of the corrugated machine 3〇2 (not shown) is switched from an exit state to a revenue state. There are no discs on it. If there is no disc on the disc, the timer 306 of the computer system 300 will begin to count to calculate the time that the disc drive 302 is maintained in the idle state 2〇6 or the standby state 208. The control unit 3〇4 switches the optical disk drive 302 to the sleep state 210 when the optical disk drive 3〇2 is maintained in the idle state 2〇6 or the standby state 208 exceeds a certain period of time. If the control unit 304 detects that the disc has been switched from the -receive state to an exit state, the timer 306 will begin timing. If the drive is maintained in the idle state or the standby state 208 exceeds a period of time, the control unit will switch the drive 302 to the sleep state 2〇8. If the computer system 3〇〇 is not shown in Figure 3, the CD player is moved to the sleep ^ 21G ¥ 'If the control unit 3Q4 detects that the disk is switched to the exit state by the distress, or exits The state is switched to the income H. The control unit 3Q4 causes the optical disk drive 3G2# to change to the standby state 0535-A21539TWF(N2); A05138; Glorious_Tien 10 200805257 state. The computer system 3G0 further includes a back/send disk key Mg, which can be switched from the receiving state to the exiting state by pressing the ^back/send disk key 31G, or switching from the exiting state to the receiving status. Alternatively, the disc can be pushed to the disc player 3G2 by an external force, and the disc is switched from the exit state to the income state. ^ Secret · ^ bracket - automatically respond to the module ground. In the case of the disc, for the sinister sinister 210, the automatic response module will replace the 〇2 response to an operating system (not shown) for the non-media access command issued to the disc drive to make the disc The machine can be trained in the state of sleep. When the disc player is in the dormant state, it will respond to an engraving access command issued by the 5H operating system. Therefore, the medium-soft weight setting command is 208 〇 under the cutting machine 302, and the control unit 3〇4 of the standby computer system 300 is more achievable (1st In the power management method shown, the optical disk drive 302 can be operated in a "use state" (2f9 302 in Fig. 2, the closed state (214 of Fig. 2). 212) and one or more The embodiments are intended to assist the reader in the art that is not intended to limit the scope of the invention, and is within the scope of the description (10). 535^21539TWF(N2); A05138; Glorious_Tien 200805257 [Simplified Schematic] FIG. 1 is a state diagram of a conventional multimedia command (MMC) protocol; FIG. 2 is a power management method of the present invention A state diagram of an embodiment of the present invention; FIG. 3 is an embodiment of a computer system proposed by the present invention for implementing the power management method of the present invention.
