In such case, the triggering member 230a is capable of (1) triggering the computer accessory 200 to temporarily cut off the external power Pe and then restore the external power Pe while the external power Pe is already outputted by the computer accessory 200; or (2) triggering the computer accessory 200 to output the external power Pe while the external power Pe is not yet outputted by the computer accessory 200.

When the power state of the notebook computer 100 is the normal operation state, the change of the external power Pe will not change the power state of the notebook computer 100. When the power state of the notebook computer 100 is the waiting to be awakened state, as illustrated in STEP 140, temporarily cutting off and then restoring the external power Pe triggers STEP 150 to perform the wake-up operation, so as to switch the power state of the notebook computer 100 to the normal operation state, as illustrated in STEP 150.

In some embodiments, as described above, STEP 130 is to trigger the power delivery controller 220 of the computer accessory 200 to temporarily stop outputting the external power Pe through the triggering member 230a disposed on the computer accessory 200, and then restore the external power Pe. In some embodiments, as described above, STEP 150 is to trigger the notebook computer 100 to perform the wake-up operation to switch the power state from the waiting to be awakened state to the normal operation state.

As shown in FIG. 3 and FIG. 4, after the notebook computer 100 performs the wake-up operation, the method is to continuously determine whether the input device 300 is operated by the notebook computer 100, as illustrated in STEP 160.

If the input device 300 has not been operated for a preset time period, for example 10 minutes, the notebook computer 100 is switched to return to the waiting to be awakened state to reduce power consumption, as illustrated in STEP 170.

Referring to FIG. 1 and FIG. 5, a computer accessory 200 according to a second embodiment of this disclosure is provided for connecting to the notebook computer 100, to establish the computer system 1.

In the second embodiment, triggering member 230a is electrically connected to the USB host controller 240 to be indirectly connected to the power delivery controller 220.
