Apple Repair program:
Apple released a document as part of it’s Service Source in 1991 detailing the issue and steps to replace the mouse. Free mouse replacements were offered through June 15, 1993.
A certain design of this mouse was susceptible to electrostatic discharge (ESD) damage and failure. This mouse did not have adequate shielding for safely discharging static electricity, which causes the charge to hit the control board and disable the Application Specific Integrated Circuit (ASIC) controller. While there was no electrical shock hazard to customers and no potential damage to the system the mouse was connected to, it could destroy the mouse itself.
At the time, returning the damaged mouse to Apple or service providers would get you a new one.
