Need to remove the entire case off Compaq Portable

[RoadWarrior]

I believe as I said in the general discussion thread, that a capacitor or something burned up in the power source. The biggest problem now is trying to figure out how to take it out. I can't access it from the bottom, I can't get to it from the top. The only possible way I think is to take the rest of the case off but I don't know how too. The carrying handle is screwed to the metal frame, so I get get to it from the back. That means only the front?

I found this on a couple of sites about the computer:

The power supply had a special wrench to remove the lower lock screw. Then the power supply would slide out where the connectors could then be removed.

But mine is a 1985 So they must have changed the design by that time because I see no place for any time of wrench.
