Is this static electricity or leakage in mac mini m4? How to judge and how to avoid it?

I have been using the m4 version of the mini for some time. When plugging in and unplugging the usb device or when forced to turn it on or off, it will inevitably touch the surface of the machine. It will be electrified at a very high frequency, and it is not a slight touch. It can numb my hands, which makes me a little afraid.
As for why I wanted to touch him, I connected a c-to-a cable, and the keyboard and mouse receiver plugged into it. Occasionally: the computer cannot wake up after hibernation. I checked and found that the connecting cable is not working, causing my keyboard and mouse to be actually disconnected, so I cannot wake up even if I press the keyboard. Just plug and unplug the c port of the cable again. But when it touches the machine, it is charged

Poster Dec 9, 2024@ Anonymous8510 I don't touch it much, it's quite smooth in my impression, and I don't feel rough

Poster Dec 9, 2024@ Anonymous454 The built-in power cable I use is plugged into two holes. Would it be a common phenomenon if I don't change the cable? I don't seem to see anyone else talking about this problem

Anonymous8510 Dec 9, 2024@ Poster # 4 This shows that this machine should have no leakage at ordinary times. Maybe people have static electricity on them?

Poster Dec 9, 2024@ Anonymous8510 I don't know. I am prone to static electricity in winter. I will be electrocuted when I touch the door handle or anything else, but it is relatively slight. It is not as hard as when I touch the mini

Anonymous4232 Dec 9, 2024https://www.v2ex.com/t/1062584 Determine whether it is the Y capacitor leakage current, or whether the charger or neutral wire is really leaking, and try changing the charger and bringing it to a Starbucks socket or something like that The electric pen will light up when measured, or it may be the Y capacitor leakage current, not the true leakage If you want to solve the problem of Y capacitor leakage current that complies with safety regulations but feels uncomfortable, you need a charging head that is effectively grounded for charging I recently bought a good model from Haibis. It has a digital display, 200W 3C2A, grounding, dynamic distribution and continuous charging. There is also a new model with 6 C ports 380W, which is also grounded

Poster Dec 10, 2024@ Anonymous454 was electrified again today, and it was electrified twice in a row. It didn't feel like static electricity, and the static electricity usually ended at once. And I found that the edge of the machine feels as if there is no battery, and the top will be a little bit. What kind of triangular insert do you want? I searched on tb and couldn't find a match. Are there any keywords?
