Considering the problems in reliability the "Professional PowerBooks" have sometimes, that's why I got a G3 iBook clamshell 366MHz graphite SE Tokyo Revision B model. Not as fancy, not as fast, not as easy to fix when something does break, but except when the temperature in our little part of the world gets too hot (at which point it flakes out until it cools off again, then it will resume (as proper as possible) operation.

Strange that NVRAM and PMU reset key combos act like they should but have no effect though, even with the battery removed, but oh well-it still is an awesome baby. And no, I don't mind trading incredible reliability in a considerably used 10 year old laptop for its toilet seat looks...because it's Graphite!

Hope that helps somehow!
