I bought a new PC last week with Windows 8 on it. The PC is plugged into the master socket of a power strip. I also have a small lamp plugged into the same power strip.
When I turn that lamp on or off, a sound is played on the Windows 8 PC!!!
I could not figure out what sound is played exactly and there is no sound event named 'External device switched on' :-)
I guess switching on the light changes the power consumption in the power strip, but why would the PC and even the OS bother about this?
How can I turn this off?
The sound is not played every time I switch the light on or off, but on average every second time.
