Why is it that sometimes when i’m haveing problems with elektronic devices, support says that i have to wait 10 seconds before turning it on after turning it off?

Transformers can have surface voltage left in them until the load pulls it down low enough to where the device completely loses power. You may see on some devices when you unplug the lights may remain on for a short duration. Boards also have capacitors which act as a battery and also need a little time to drain.
* You are told to turn a device off and on to clear its memory and allow it to start fresh from a default state.
* Power supplies contain capacitors to “clean up” and smooth out the electricity supplied to electronic devices. Microcontrollers and other components have further capacitors for the same purpose.
* Capacitors store energy, and will release it even after the power supply is turned off. This may partially power some memory and cause old data to be stored.
* Therefore you are told to leave the device off for 10 seconds to allow all the energy to discharge, to allow all memory to clear for a full reset.

The power supply can remain energised under standby conditions for a substantial time. Some industrial devices I have worked with could stay on for over 10 mins after turning the mains supply off.
