I own a Lenovo G510. I use

  • a cooler base

  • external mouse

  • keyboard

  • monitor

  • 2:1 speakers

Whenever I plug something to a wall socket that is near to the one that I use to power everything (when logged in windows) I get the usb inserted sound. I am not sure if that happened from when I first bought my laptop but I observed it now, nearly 9 months after I purchased it.

I assume that due to the power consumption changing a little at the moment I plug a device to the socket, something misleads windows to act like it detects external hardware. It annoyed me a little and thought I should search for it but I couldn't find anything.

In General, Lenovo products have a bad reputation when it comes to power leaks. Do you think that that's the case? and if yes, should I try to repair it?

    the stuff you mentioned (I use a cooler base, external mic, keyboard and monitor is there any other?) Are they connected to the same Electrical Socket AND to the PC via USB ? Aug 24, 2015 at 13:11
  • Yes, keyboard and cooler are connected to the pc via usb and mouse is connected on the hub of the cooler.PC, Monitor, 2:1 speakers and an office lamp ( I forgot to mention) are all on same the same socket. Propably it would be a good idea to distribute them equally. Aug 24, 2015 at 14:18
  • What I was trying to say is that if you have a device such the USB hub which is connected to the same electric socket as the the laptop and ALSO connected to the laptop via USB, then most likely there will be an electric disruption when you plugin/out other devices from the socket. The question is, what kind of socket are you using? if it's wall plugin one then make sure you are using a Level -A one or even better use a high quality electric socket extender. Most Likely it's the mouse getting disturbed since it's connected to the weak hub which in turn connected to the laptop. Aug 24, 2015 at 19:30
  • The hub is powered from the laptop through usb port. But what you said made sense. I actually tried unplugging everything and the sound didn't occur when I connected something to the wall socket. I think it is caused by some disruption in one of the usb3 ports (where the keyboard is plugged). Aug 25, 2015 at 22:08
