Hi Bluto,
MaG posted these directions in an older thread, see if they help you:
If you can find your way to the hall with lockers on one side and the steps to go to the morgue on the opposite side - there are 2 doors on the other walls.
Right of the steps is the door to the electric chair room.
Opposite wall to the is another door that should have been opened from the other side. This door leads to the computer room - lab area.
