The Macintosh Portable Service Guide

( Place Holder )

So you have a Macintosh Portable?

They can be really great machines to use and enjoy!  The Mac Portable has a Unique and clever design!
Their age can be a problem, Getting them to a fully functional state again will for sure require some involvement from you.

_ Bad Caps - They are probably all bad, The Mainboard will need a complete Re-Cap service!
_ Dead 6.8v Sealed Lead Acid battery, Replacements / Suggestions
_ Dead 9v battery,  there only to keep the sleep mode or time, ONLY when changing(swapping) the main lead acid battery, with a charged one.  Other wise the 9v battery just sits there and does nothing.

_ Common Cap Goo dammage 5120 and 5126
_ Buck/boost 6.8v to 12v (Converter Circuit) issues and component replacement
