Most computers receive electrical energy through a standard wall socket, others receive electrical energy from batteries.
Large mainframe computers sometimes receive electrical energy through cables wired directly to the main breaker box, without any plugs/sockets.
Depends what the source of electricity is.
A computers energy source is electricity. When using a computer plugged in or not it is drawing electricity from the battery or from a plug which is connected into the PC and a wall outlet. When there is no electricity the computer cannot function.
