my laptop is a Dell XPS 13.
I noticed that when I plug in a mouse in a usb port while the pc is off an instantaneous light flash takes place on the monitor. Also I noticed that this happens only if the power supply is disconnected.
Is this a normal behaviour? Why?
Thank you in advance.
Is there anyone who can help me with this strange behaviour?
Thank you for your message.
Does this happen on all USB ports?
Disconnect the power cord & use the power button to shut down the computer & once turned off, connect the USB device & check if this happens.
Does this happen only when the USB mouse is connected, have you tried using other USB devices.

Hi, thank you for your reply.
I noticed that behaviour repeatedly about two moths ago; I tried again as you have suggested but I have not managed to replicate the problem again.
In case it will happen again in the following days, can I point it out in this same conversation?
Anyway, did you ever hear of other users facing a problem like this?
Glad to know that the issue has been resolved for now.
This is not a known issue & we haven’t come across any such issues until now.
