The embodiments of the present invention are not so limited, and the present invention is intended to encompass any and all computer power states. In block 502, a wireless receiver, which may be an infrared receiver, an RF receiver, other wireless remote receiver, or a wireless keyboard receiver, will receive a signal from a wireless remote or wireless keyboard. If in block 504, the information derived from the received signal will be judged to take action other than the remote control power button press, then the remote button processing will be in block 5-6 Take appropriate action, such as by fast-forwarding the video section or increasing the audio volume. On the other hand, 10 if the received signal indicates that a remote control power button is pressed, the processing will continue according to the power state of the computer. In block 508, if the computer is in the '0FF power state, the computer will switch to the λλΟΝ〃 power state in block 51〇 when a remote control power button is pressed. The action from the 'OFF state of power state to '0' state of power 15 includes causing the computer's power supply to generate VMAIN and restarting the processor and operating system of the computer. When the computer is in the OFF power state, VSTANDBY will be provisioned to provide power to the wireless receiver of the computer, which in turn causes the receiver to detect the transmitted signal and initiate a power state transition. In block 508, if the computer is not in the '〇FF" 20 power state, then the power state handler continues in block 512. In block 512, if the computer is in the 'SLEEp〃 power state, the computer will transition to a 'ΌΝ〃 power state' in block 514 when a remote control power button is pressed. "SLEEP" power status includes a variety of users 18 200836054 Optional system configuration. When entering the 'SLEEp〃 state, the operation from \'SLEEp" sorrow to 〃 state depends on which hardware is invalid and has been stored. The system context is performed. For example, if the RAM is powered on and the system context is stored in RAM when the "SLEEP" state is initiated, a 5 restart boot action may not be required. Similarly, if the system context is stored on the disc, a full reboot action may not be required, but the context must be recovered from the disc rather than from RAM. In block 512, if the computer is not in the "SLEEP" power state, then in block 516, the power state handler will continue. 10 In block 516, the computer is in a '〇N〃 power state. If the power button of the wireless remote control has been depressed for at least a critical time (e.g., '4 seconds), then in block 52, the power state will be entered by making the ^_ invalid. After vMAIN is disabled, the computer's power supply will continue to generate VSTANDBY. VSTANDBY provides power to components (such as wireless 15 remote receivers) that initiate a transition to a power-like action when a trigger event is detected (eg, receiving a power control button press action), such as a block. 508 is shown. If, at block 516, the power button of the wireless remote control is depressed for a critical period of time, the computer is converted to a \, SLEEp 20 state at block 518. As previously mentioned, the LEEP state includes multiple power sources. Reduces hardware sorrow, ranging from reducing processor clock frequency to saving or not saving context and shutting down the computer. Therefore, a specific set of specific operations will be enabled to define various specific configurations for the %LEEP state. The exemplified embodiments of the present invention can be modified by those skilled in the art without departing from the spirit and scope of the present invention. The embodiments described herein are illustrative and not limiting. Various modifications and modifications of the system and device can be made therein. Therefore, the scope of protection is not limited to the embodiments described herein, but only by the scope of the following 5 patent applications, which should include the scope of the patent application request.
