Compal DL71 ... security issue?

Hi, I'm a newbie here. But not on comps. However, I am new to this Compal. I bought a deliquent account storage unit at auction. This comp was in it. However, it will not power on at all. On the left side, at the back, there is a small orifice with an emblem of a lock on it. It's shaped similar to a bird in flight, but vertically. Is this a device to stop from powering up the comp unless there is a key inserted? ... if so, is there a quick workaround? ... Seems to be a good comp and I've about had it with this ancient satellite i'm on now. Any help or suggestions are welcome.
