R.I.P. MacBook battery

The golden week ended today so in the morning I popped the MacBook open to update the Documents folder via Dropbox. There was no reaction to the on switch so I plugged the laptop in thinking that I managed to deplete the battery completely. However instead of the usual orange charging light the charger lit up in a happy green and the menu bar icon reported: not charging. The problem persisted…


OS X acknowledges the presence of the battery but reports its full charge capacity at 0 mAh and refuses to charge. Reseating the battery or resetting the PMU didn’t help either. In addition the laptop now often boots with a flashing white light similar to the PMU reset indication. All this after only 67 cycles.

I spent most of the breaks today hunting for power outlets in classrooms. Of course the newer ones have desks with outlets for each seat but I never seem to be able to have classes there. The newer auditoriums have a few along the walls, but in one of the old buildings I had to sit in the very first row and nick an extension cable from the professor’s pulpit.

Hopefully I can visit the Apple Store in Osaka on Wednesday. I bought Snowflake in June 2008 after the ominous grapefruit juice incident so it’s still under warranty (I hope).

I still shudder at the thought of such things happening when I’m in Hungary with no Apple Stores around.

  1. Jah, Li akkupakkok tipikus hülyesége. Nincs annak semmi baja, csak mélykisülésbe vitted. A megoldás annyi, hogy szétszeded az akkupakkot (ezt egyszerűbb leírni, mint megcsinálni, de nem lehetetlen), lekötöd az elektronikát, és CC-ben nyomatsz neki egy kis töltést pár órán keresztül. (Töltőáram az akku kapacitásának 5%-a, és a töltés ideje ne haladja meg az 5 órát.) Aztán visszakötöd az elektronikát, beteszed a laptopba, és hagyod teljesen feltöltődni. Probléma megoldva.
