MacBook memory upgrade

My step-mother-in-law is over with her 512mb macbook, and a box from crucial with more DIMMs. Time for memory surgery. Since she gave me her old G4 TiBook in trade for the effort of doing a memory upgrade, I knew I had to do a good job. ;-)

The do-it-yourself instructions at the apple MacBook Support Site are quite good. However, they don't provide any info about how to troubleshoot it.

Turns out that if the memory isn't seated correctly, the macbook's sleep light will flash or blink - not the throbbing you see when it's asleep, but actually blinking. A blinking sleep light means that the memory isn't seated correctly, and you really need to ram the stuff in there. (ram the RAM? Pun wasn't intended at first, but hey, gotta go with what works for you.)

Ironically, I had been thinking that this was the first computer upgrade for which I wouldn't need my NeXT memory extraction tool, but turned out I was wrong - it was just the thing to push the memory down into the slots after it was past where my fingers could push it.

Many many thanks to Conradium's blog for info on this.
