hello there
I have a decent cooler master 400 watts psu and a decent gaming pc .
for the last week i am experiencing this problem that when i turn on the electricity switch but the PC is turned off, all the component's (i.e Mouse,Keyboard and Ethernet Socket) Lights are On.
It never happened before.

But when I turn on my PC and then shutdown it myself , all the lights turns off then.

Anyone know why mouse/ethernet lights are on even when my pc is turned off.
