I've seen plenty of them.  Plug and socket connections have been the
bane of servicemen since the invention of electronics.  Printed circuit
boards with an edge connector plugged into a socket seem to be the

Desktop computers marry the edge connection problem with PCI cards that
are attached at one end to a different part of the chassis that might
pull the card out of the socket.  Very few have any sort of clamp to
hold the cards into place from a position that does the job properly
(e.g. top and centre, directly on the opposite side of the PCI slot),
and the case is quite often flexible.  Just picking them up and moving
them around is enough to turn some computers into crash boxes.

And the old Apple ][s were infamous for needing the ICs pushed back into
their sockets periodically.

around to refresh the display, like how you cleared the screen on the
1970s etch-a-sketch toys.
