And S103, powering off the pen.

Specifically, when the voltage (+ VADP) of the Adapter (Adapter) is higher than the upper limit of the set voltage range, i.e., 23V, PWRBTN _ KB in fig. 2 is pulled low all the time, and the pen is powered off.

S107, detecting whether the discharge current of the battery reaches a set current limiting value and the temperature of the CPU reaches a set maximum temperature value in the machine learning process; and if the discharging current of the battery reaches a set current limiting value and/or the temperature of the CPU reaches a set maximum temperature value, executing the step S108, and if the discharging current of the battery does not reach the set current limiting value and the temperature of the CPU does not reach the set maximum temperature value, executing the step S109.

Wherein the set flow limiting value is determined according to specific conditions, and the set maximum temperature value is 100 ℃.

And S108, exiting the machine learning process, and setting the working wattage of the CPU corresponding to the previous stage of the stage where the machine learning process exits as the final working wattage of the CPU through the embedded controller.

S109, continuously detecting whether the voltage of the adapter is lower than the lower limit value of the voltage range; if the voltage of the adapter is not lower than the lower limit value of the voltage range, continuing to execute the step S106; if the voltage of the adapter is lower than the lower limit value of the voltage range, step S110 is executed.

Specifically, when the machine Learning process needs to be exited, the comparator 1(compare circuit part1) in fig. 2 flips, sends a PROCHOT _ N signal, triggers the CPU to perform fast frequency division, and sends AC _ OFF to notify the Embedded Controller (EC) that the machine Learning process (Adapter Learning) exits.

And S111, setting the working wattage of the CPU corresponding to the stage of exiting the machine learning process as the final working wattage of the CPU through the embedded controller.

And S112, maintaining the battery power supply state by the pen power supply.

It should be noted that the final wattage of the CPU determined by the method provided by the present invention can be reset in the corresponding software of the pen, or released after the next learning process.
