This is an actual alert to IBM Field
Engineers that
went out to all IBM Branch Offices. The person who wrote it was
very serious. The rest of us may find it rather funny.
Abstract: Mouse Balls Available as FRU (Field
Replacement Unit) Mouse balls are now available as FRU.
Therefore, if a mouse fails to operate 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. Foreign balls can be replaced using the pop-off
method. 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.
To re-order, specify one of the following:
