Unable to boot: check whether the light is on when charging, if not, check the power adapter and USB cable; Confirm OK, that is, there is something wrong with the pen. I suggest resetting first. If it doesn't work, it needs to be repaired. Focus on checking whether the crystal oscillator lamp flashes, and reset it first if there is no sound. If it is not effective, the horn cable breaks or falls off.
