According to iStat Pro, a system monitoring Dashboard widget, the battery in my 14″ G4 iBook only has 31% of the endurance that it shipped with, a bit more than a year ago. No wonder I have been unplugging it from the wall recently only to find less than an hour worth of power available. Of course, the figure it gives is untrue. With somewhere between ten and fifteen minutes remaining, the computer will simply turn off – hopefully in a way that seeks to avert file corruption. Every little click of my hard drive now makes me fearful of losing this vital academic and personal tool. The experience of the succession of iPods has made me wary. Backups as frequent as I can bear to run them seem the best option.
Since it would be at least US$129.00 to replace my iBook battery, I must simply tolerate the lack of stamina until such a time arises (probably once I have tunneled my way out of student debt) to strip this machine of most of its RAM and move to something snazzier.
[Update: 13 October 2008] My original iBook battery has now failed completely. It cannot run the computer for even a fraction of a second, the LED charge display on the bottom of the battery doesn’t work, and the computer often cannot detect that the battery is present.
