Windows 7: Spark made when plugging in computer

Spark made when plugging in computer

Hey guys, occasionally, when I plug in my computer, a little spark is made. Is this something I should worry about? Or is it just because the plug is being plugged in upside down as the Schuko plug variant used in Korea allow you to plug in the line pin into neutral and the neutral pin into line? I assume that modern computers have protection against this but just in case, I am asking this as usually sparks in electronics can damage them. Thanks.

What happens if you turn the switch on the power supply to off first? Most power supplies, if the power supply switch is left on or ones that do not have a switch, when plugged in can draw a small arc. Its nothing to be concerned about, as many electronic/electric items will do that - it starts to draw current as soon as its plugged in.

On a PC, if the power supply power switch is on, the power supply is working to some degree.

Turn off your power supply before unplugging or plugging in.
Anytime you get a spark at the power supply you have a surge. Computers don't like surges.

Well, I can't unpower it as it has no switch. By the way, I am going to be inactive for the next few hours because of sleep so please wait for me to reply.

Turn the power off at the wall before plugging it in, always turn it off at the wall. Only turn it back on when everything's plugged n at aboth ends.

Ok, I'll do that on my surge protector since the wall outlet does not have an ON/OFF switch.

If you surge protector is working properly when turned off their should be no power to the computer power supply. Therefore their should be no spark.
Your power supply is not listed in your system specs.
What power supply are you using?

It is just a normal Dell XPS 8700 power supply. I just for some reason never thought about turning the surge protector off. I think we might be taking this a bit too far now. Thanks guys for helping me.

It's not to far.
Anytime you are getting sparks with the use of a computer it is a problem that must be fixed.
I turn off my surge protectors anytime my computers are not in use. It cost nothing and all you have to do is push a button.
