Mouse Balls ... Old One But Still Entertaining

I don't know how they wrote this with a straight face.

This apparently was a real memo sent by IBM to its employees in all seriousness. It went to all field engineers about a computer peripheral problem. The author of this memo was quite serious. The engineers rolled on the floor! (Especially note last sentence)


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 Unit).

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 manufacture 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 repairperson 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.
