Plastic MacBook (Black)
Some banding appears from the plastic case molding process. 100% speeed 50% power on a 35W laser has worked out for us so far. (30% is much too low)
Plastic Apple iBook and white MacBook

So far, these cannot be (easily) etched or marked because the case is made of polycarbonate which turns yellow and chars when laser cut or etched! We've attempted some low power and multi-pass etching, it's promising but so far the demand is pretty low.
Any additional information or hints should be put here!
