插上电源后键盘左下角就吱吱的发出响声,拔掉电源后就不响了!响声是间断周期循环的嗯嗯声。
请问是什么原因,求帮助!
After plugging in the power supply, the lower left corner of the keyboard squeaks and makes a noise, and when the power is unplugged, it does not ring! A boom is a muttering sound that loops in an intermittent cycle.
Please ask what is the reason, please help!
