Thus, the usage of the instant messengers can be unattended and ambiguous.

Abstract: A holder for securing a printed circuit board in an edge connector on a mother board in a computer having a cover. The holder body is secured to the top of an installed printed circuit board. An adjustable post is held by the holder and is adjusted so that the head of the post extends slightly past the plane in which the computer cover rests. Next, the cover is installed depressing the head. The head is spring loaded on the post, thereby providing a continuous force on the printed circuit board to hold into the edge connector on the mother board.
