12″ iBook G3 (Mid 2002)

Apple improved the already popular Dual USB iBook by boosting CPU speed 100 MHz and using a newer version of the G3 with a twice-as-large 512 KB level 2 cache. The entry-level 600 MHz model has a CD-ROM drive, while the 700 MHz one includes Apple’s  Combo (CD-RW/DVD) drive. The new Mobility Radeon is up to 35% faster than the graphic chip in the previous model.

12" Dual USB iBook G3Apple distinguishes the Mid 2002 models by their 16 MB of video memory (VRAM).

MacInTouch has called the dual USB G3 iBooks Apple’s most unreliable notebooks ever. According to their survey of iBook and PowerBook Reliability:

…by affected percentage of models, the G3 iBooks were the worst by far, with more than half requiring logic board replacements. Apple created a warranty extension program for some versions, but not all. (MacInTouch readers are still reporting newly failed iBook G3s, and the warranty extension program has ended.)

The white 12″ iBook G3 series became much less reliable through its first five revisions, reaching a 73% failure percentage! The last revision dropped to a 49% failure percentage – much improved over the previous model, but still unconscionably high. The problems appear to have been solved, for the most part, in the newer iBook G4 series.

Keep in mind that Apple had an extended replacement program on many iceBook models, so most problematic motherboards have already been replaced.

It can boot Mac OS 9.

  • There is an incompatibility between the Kensington Startup ADB extension (part of Kensington MouseWorks) and the Trackpad control with Mac OS 9.0.4. The trackpad will respond during boot, but not after the extension loads. The solution is to disable the extension. This may apply to other versions of Mac OS 9 on ‘Books with USB ports.
  • Portable Computers: Models Which Do Not Have a Backup Battery notes the iBook has no backup battery to retain time and other settings when the main battery is removed. A small capacitor holds enough energy to maintain PRAM contents for 20 seconds, so switch batteries quickly.
