This apparently was a real memo sent out by a computer company to its employees in all seriousness. It went to all field engineers about a computer peripheral problem. ..
RE: Replacement of Mouse Balls.
If a mouse fails to operate or should it perform erratically, it may need a ball replacement. Mouse
balls are now available as FRU (Field Replacement Units). Because of the delicate nature of this
procedure, properly trained personnel should only attempt replacement of mouse balls. 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 by 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 person have a pair of spare balls for maintaining optimum customer satisfaction. Any customer missing his balls should contact the local personnel in charge of removing and replacing these necessary items. Please keep in mind that a customer without properly working balls is an unhappy customer…
