2. Remove any diskettes from the diskette drives.
3. Unlock the keylock if your system has one.
4. Unplug all computer power cords from electrical outlets. Make a note of all the cables and cords connected to the rear of the system unit.
5. Carefully place the system unit face down on a flat surface. (Ed. Place a thin towel or cloth over the screen before you set the system face down on any surface. This will prevent scratches to the monitor glass.)

Caution: Remove the cable from the cable hook as
you lower the bottom cover to prevent damage to the system. (Ed. Don't just let the bottom of the system unit fall as

When opening your Model 25, you may notice that the cable hook that holds
the power and display cables is no longer attached to its correct place in the

pinching the cables when you reinstall the bottom cover.
The cable hook falls out after a number of years because the adhesive pad it
is stuck to loses its stickiness.
To fix this problem is easy. Simply remove the wires from the cable hook,
put some super glue on the cable hook and cable hook pad. Press both together
and allow them to fully dry. Reinstall your cables into the cable hook, close
the bottom cover of the system, and you will have fixed the problem.
