Batteries Yes
Mounting Technology Through Hole (PSU), SMD (Logic Board)
Capacitor Types Aluminum Electrolytic

The Macintosh Portable was sold by Apple Computer from September 1989 to October 1991. Like all Macintoshes of its era, its original surface-mount electrolytic capacitors leak their contents and require replacing for both functionality and to protect critical traces on its circuit board from being eaten by electrolyte.
