   • 1992 November 18, Danny W. McCampbell, “How long should I charge my PB batter?”, in comp.sys.mac.hardware‎ (Usenet):

     When I charge my Powerbook Battery by hooking up the AC
     adapter to my PB, should I disconnect the AC adapter
     when the chooser's Battery shows that the batter is charged?
     Can I safely leave the AC adapter hooked to the PB so
     I can use the batter for later? Help, I do not want to tear
     any thing up.

   • 1997 May 2, Joerg Pollmann, “Mein PB spinnt :-(”, in maus.sys.mac.hard‎ (Usenet):

     Mein braves PB190 denkt immer öfter, es sei kein Netzteil angeschlossen
     und fängt an, auf Akku zu laufen. Da nützt kein Rütteln am Netzanschluss
     und kein Reset des Powermanagers, das Teil läuft so lange auf Akku, bis
     dieser vollständig leer ist. Erst nachdem ich den Akku entfernt habe und
     ein paar Mal versucht habe zu starten ist das PB dann irgendwann endlich
     bereit zu erkennen, daß die ganze Zeit der Netzanschluss vorhanden war und
     fängt an, denn Akku wieder aufzuladen.
