After the G5's memory upgrade went well, the 12" iBook 1.2GHz was next on the list to receive an 256MB memory upgrade, which would bump its total RAM to 512MB.
Just like expected, the iBook's memory upgrade was a bit more challenging but thanks to Apple's helpful document: Memory Card Replacement Instructions not really scary.
Before:
Inside:
Unlocking the keyboard and flipping it over towards the palm rest exposes the iBook's Airport Extreme Card
The Airport Extreme Card can be easily pulled out of the slot and the antenna cable doesn't need to be disconnected during the memory upgrade procedure. Putting the Airport card temporarily into a piece of the anti-static bag the memory chip shipped in, seemed to be a good idea.
Installation:
Inserting the DIMM is not difficult after the Ram shield (four screws) has ben removed. Again, I needed to push the DIMM down into the slot a little harder than I had expected, to allow the ejectors to snap into place.
After:
After re-inserting the metal RAM shield and the Airport card, closing the case, and putting the battery back, the iBook booted and the "About This Mac" dialog showed 512 MB DDR SDRAM.
