To plug or not to plug?

[Lioness]

My Asus manual states "Make sure to unplug power supply before adding or removing expansion cards or RAM". On the pcmechanic site it states, "Turn off the computer, unplug it, and take the case off."

Exactly what am I unplugging?

1. The power supply in my PC case
2. The power cord plug to the wall outlet
3. The power supply unit in the PC case and the plug to the wall outlet.

There is conflicting information on this simple but important fact all over the web.

My common sense tells me to UNplug ONLY the power supply unit and leave the power cord plugged IN into the wall. By doing this I touch the side of the case to ground myself. Right?

thanks

I think they mean unplug the power cord from the power supply at the back of your computer. You can leave everything else plugged. Then to ground yourself, just touch any metal part of the case. That usually removes the static electricity. Hope this helps.

And then take the anti-static steps that the previous posts said to take. This will reduce the possiblity of a static charge damaging any sensitive electrical componets and devices.
