This is an actual alert to IBM field engineers that went out to all IBM
branch managers. The person who wrote it was very serious. The rest of us
may find it slightly amusing.
Abstract: Mouse Balls available as FRU
Mouse balls are now available as FRU (field replaceable units).
Therefore, if a mouse fails to perform, or should it perform erratically, it
may need a ball replacement.
Because of the delicate nature of this procedure, replacement of mouse
balls should only be attempted by properly trained personnel. Before
proceeding, determine the type of mouse balls by examining the underside of
the mouse. Domestic balls will be larger and harder than foreign balls.
Ball removal procedures differ depending upon the manufacturer of the
mouse. Domestic balls are replaced using the twist off method. Mouse balls
are not usually static sensitive; however, excessive handling can result in
sudden discharge. Upon completion of ball replacement the mouse may be used
immediately. It is recommended that each replacer have a pair of spare balls
for maintaining optimum customer satisfaction and that any customer missing
his balls should suspect local personnel of removing these necessary items.
