Flash on the monitor

This question is not answered

Hi,

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.



    Please click on my Dell username & send a private message with the service tag, registered name & email address.

  • 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?

    Thank you.

  • Glad to know that the issue has been resolved for now.
