Detailed Description
Referring to fig. 1, fig. 1 is a block diagram of an electronic device 100 according to an embodiment of the invention. The electronic apparatus 100 includes an electronic device 120 and a power key controller 110. The electronic device 120 includes a power key 122, a Basic Input/Output System (BIOS) 121, and a Platform Path Controller (PCH) 123. The bios 121 is configured to operate to enable or disable a power key function of the corresponding power key 122, and the platform path controller 123 is in signal connection with the bios 121 and includes a hot trip pin (THERMTRIP)1231 and a power key Pin (PWRBTN) 1232. The power key controller 110 is in signal connection with the power key 122 and the platform path controller 123.
When the power key function of the bios 121 is disabled, if the electronic device 120 is in a power-off state, the power key 122 is operated to enable the power key controller 110 to transmit a power-on/off signal 135 to the power key pin 1232, so that the electronic device 120 is switched from the power-off state to a power-on state; if the electronic device 120 is in the power-on state and the time for operating the power key 122 is less than a threshold (at this time, the power key 122 may be pressed for a short time), the power key controller 110 does not transmit the power-on/off signal 135 to the power key pin 1232, and if the time for operating the power key 122 is equal to or greater than the threshold (at this time, the power key 122 may be pressed for a long time), the power key controller 110 transmits a forced power-off signal 134 to the hot trip pin 1231 to allow the electronic device 120 to perform a forced power-off.
Therefore, the shutdown caused by mistakenly touching the power key 122 when the electronic device 120 is in the power-on state can be avoided, and meanwhile, the forced shutdown function can be kept, so that the effects of fool-proofing and convenient use can be achieved.
The electronic device 120 may be, for example, a service-type point of sale device (post of sale device) and the power key 122 may have a key type and may be pressed. The user can set the BIOS 121 from the BIOS menu through a Serial Peripheral Interface (SPI), so that the power key function corresponding to the power key 122 can be disabled or enabled. The power key Controller 110 may be, for example, an Embedded Controller (EC), which can know the enabled or disabled state of the current power key function through an Enhanced Serial Peripheral Interface (eSPI) 131 transmitted by the platform path Controller 123, and perform corresponding processing when the power key 122 is operated.
Generally, before the power key controller 110 is not additionally provided, if the power key function is enabled, a signal generated after the power key 122 is pressed may be transmitted to the power key pin 1232 of the platform path controller 123, so as to enable the electronic device 120 to switch the power-on state, the power-off state or the forced power-off state; on the contrary, if the power key function is disabled, pressing the power key 122 will not transmit a signal to the power key pin 1232, and will not cause the state of the electronic device 120 to change. In the embodiment of fig. 1 of the present invention, since the power key controller 110 is additionally connected between the power key 122 and the platform path controller 123, when the power key function is disabled, the power key controller 110 determines whether to transmit the power-on/off signal 135 to the power key pin 1232 or transmit the forced power-off signal 134 to the hot trip pin 1231 according to the state of the electronic device 120, and the power key controller 110 can know that the electronic device 120 is currently in the power-on state or the power-off state according to the SLP _ S3 signal 132 and the SLP _ S5 signal 133. In other embodiments, the power key controller may include a plurality of input pins, a plurality of logic circuits and a plurality of output pins, the input pins receive input of electric potentials, the logic circuits may be, for example, comparators, and the like, and the logic circuits may determine whether the power key function is disabled or enabled by comparing the electric potentials and know the state of the electronic device, and the output pins may output high or low voltages according to the corresponding comparison result or determination result, which is not limited to the above disclosure.
In the electrical connection, the power key controller 110 is electrically connected to the thermal trip pin 1231 and the power key pin 1232, and determines the signal transmission according to the current state of the electronic device 120 and the time when the power key 122 is operated. Therefore, when the power key controller 110 determines that the electronic device 120 is in the power-on state, the power-on/off signal 135 is not transmitted to the power key pin 1232 as long as the user presses the power key 122 for a short time, so that the electronic device 120 is not powered off. On the contrary, if the electronic device 120 is in the on state but the user wants to forcibly turn off the electronic device 120, the power key 122 may be pressed for a long time, and the power key controller 110 further includes a timer 111 for counting the time that the power key 122 is operated, and comparing the counted time with a threshold value to determine whether to transmit the forced power-off signal 134 to the hot trip pin 1231, and if it is determined that the time that the power key 122 is operated is equal to or greater than the threshold value, the forced power-off signal 134 may be transmitted, where the threshold value may be, for example, 4 seconds.
It should be noted that, generally, before the power key controller 110 is not additionally provided, the signal of the power key 122 is transmitted to the power key pin 1232, and the platform path controller 123 calculates whether the time of the power key 122 being operated is equal to or greater than 4 seconds, i.e. the time of the signal being continued and not interrupted is equal to or greater than 4 seconds, so as to perform the forced shutdown procedure. The hot trip pin 1231 may be triggered by a temperature sensor in the electronic device 120, when the temperature is too high, the hot trip pin 1231 receives a signal and performs a forced shutdown process, and at this time, a shutdown procedure performed by the electronic device 120 is the same as a shutdown procedure after the power key 122 is pressed for a long time, that is, a time sequence for shutting down internal components is also the same, so that when the power key controller 110 transmits the forced shutdown signal 134 to the hot trip pin 1231, the same forced shutdown effect may be achieved. In addition, if the power key controller 110 is changed to transmit the forced shutdown signal 134 to the power key pin 1232, the platform path controller 123 needs to calculate the duration of the signal on the power key pin 1232 again, which causes a delay of forced shutdown, thereby increasing inconvenience in use.
Further, even if the power key controller 110 is additionally provided, the operation mode when the power key function is enabled may not be affected. In detail, when the power key function is enabled, if the electronic device 120 is in the power-on state, the power key 122 is operated, and the power key controller 110 triggers the power key pin 1232, the platform path controller 123 calculates the time that the power key 122 is operated, and if the time that the power key 122 is operated is less than the threshold, the electronic device 120 may be switched from the power-on state to the power-off state; if the time of the power key 122 being operated is equal to or greater than the threshold, the electronic device 120 may be forced to be powered off; if the electronic device 120 is in the power-off state, the power key 122 is operated to enable the power key controller 110 to transmit the power-on/off signal 135 to the power key pin 1232, so that the electronic device 120 is switched from the power-off state to the power-on state.
Referring to fig. 2 in conjunction with fig. 1, fig. 2 is a block flow diagram illustrating a method 200 for operating a power supply of an electronic device according to another embodiment of the invention. The method 200 for operating the power of the electronic device includes a device configuration step 201, a setting step 202 and a power key operation step 203, and the details of the method 200 for operating the power of the electronic device will be described with reference to the electronic device 100.

In the setting step 202, a power key function of a bios 121 of the electronic device 120 is disabled or enabled.
In the power key operation step 203, the power key 122 is operated to control the electronic apparatus 120 to power on and power off, wherein when the power key function is disabled, if the electronic apparatus 120 is in a power off state, the power key 122 is operated to enable the power key controller 110 to transmit a power on and power off signal 135 to the power key pin 1232 to switch the electronic apparatus 120 from the power off state to a power on state; if the electronic device 120 is in the power-on state and the time for operating the power key 122 is less than a threshold, the power key controller 110 does not transmit the power-on/off signal 135 to the power key pin 1232, and if the time for operating the power key 122 is equal to or greater than the threshold, the power key controller 110 transmits a forced power-off signal 134 to the hot trip pin 1231 to allow the electronic device 120 to perform a forced power-off.
Specifically, please refer to fig. 3, wherein fig. 3 is a flowchart illustrating a step of a power operation method 200 of the electronic device according to the embodiment of fig. 2. In step 211, the user disables the power key function through the bios 121, and in step 212, the power key controller 110 knows whether the electronic device 120 is currently powered on from the SLP _ S3 signal 132 and the SLP _ S5 signal 133, and if not, proceeds to step 213 to determine whether the power key 122 is operated; if yes, step 214 is entered to allow the power key controller 110 to send the power key pin 1232 the power key switch signal 135, so that step 215 is entered to allow the electronic device 120 to be turned on.
In step 212, if the power key controller 110 knows from the SLP _ S3 signal 132 and the SLP _ S5 signal 133 that the electronic apparatus 120 is currently in the on state, the process proceeds to step 216 to determine whether the power key 122 is operated. If yes, step 217 is performed, in which the power key controller 110 counts time and determines whether the time for operating the power key 122 is less than a threshold value, and if the time is less than the threshold value, it indicates that the user may touch the power key by mistake, in step 218, the power key controller 110 does not transmit the power on/off signal 135 to the power key pin 1232, and in step 219, the electronic device 120 is maintained in the power-on state.
If the power key controller 110 determines in step 217 that the time for operating the power key 122 is equal to or greater than the threshold, indicating that the user intentionally and forcibly turns off the electronic device 120, the method proceeds to step 220, the power key controller 110 transmits the forced power-off signal 134 to the hot trip pin 1231, and proceeds to step 221 to forcibly turn off the electronic device 120.
Referring to fig. 4, wherein fig. 4 is a flowchart illustrating another step of the power operating method 200 of the electronic device in the embodiment of fig. 2, in step 231, the user enables the power key function through the bios 121, and in step 232, the power key controller 110 learns whether the electronic device 120 is currently in the power-on state from the SLP _ S3 signal 132 and the SLP _ S5 signal 133, and if not, proceeds to step 233 to determine whether the power key 122 is operated; if yes, go to step 234, let the power key controller 110 send the power key pin 1232 the power key on/off signal 135, so go to step 235 to change the electronic device 120 to the power-on state.
In step 232, if the power key controller 110 knows from the SLP _ S3 signal 132 and the SLP _ S5 signal 133 that the electronic apparatus 120 is currently in the on state, the process proceeds to step 236 to determine whether the power key 122 is operated, if so, the process proceeds to step 237 to let the power key controller 110 trigger the power key pin 1232, and then the process proceeds to step 238 to determine whether the time for operating the power key 122 is less than the threshold value from the platform path controller 123. When the time for confirming the operation is less than the threshold, step 239 is entered to change the electronic apparatus 120 to the power-off state.
If the operation time is not less than the threshold in step 238, step 240 is entered to forcibly turn off the electronic device 120.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
