So my keyboard is annepro 2 which has a detachable usb type c to usb A on it. My power supply is cx550m. They're both brand new. Ever since i moved back to my hometown, i noticed something. When i switch on the room's light after a long time, my keyboard will just power down and i have to replug it. It's not a coincidence because it happens everytime. But it only happens if i didnt switch on my room's light for a long time prior to it. Also, my monitor will flicker for a while then everything's back to normal. Everything is normal except for that and im just wondering why tbh.
