how to change power plug in ecs a928 desknote
Probably with some cutters, wire strippers, a soldering iron and a steady hand.
Unless you mean the socket within the machine, in which case the repair will probably be beyond most of us and you best get a quote from somebody able to do those repairs.
However, if it's the plug on the end of the power pack, see the first line of my post.
That's the best I can suggest with limited info.
