If a running optiplex was powered off by unplugging power cord the last time, reconnecting power cord may automatically start it again without pressing power button.  Or when the power button is pressed too long and cord unplugged, replugging power may start it automatically again. Suggest software shut down inside Windows, do not press power button to shut down the hard way.
