Sorry y'all, went through three machines and lost the pics. Have found them again, so guide and pics this weekend. LONG delay, my apologies.
Also, ANY of the SZ series can be upgraded. They're all the same basic chassis, the plethora of model numbers simply denotes differences in RAM/CPU installed, Core Duo vs. Core 2, Standard vs. Premium, etc. I'll post a guide to that too. But yes, an SZ110 is not any different than an SZ430 and an SZ160 is no different than an SZ460 except that the latter is gonna be C2D vs. CD, have more RAM from the factory and a bigger HDD, and have Vista vs. XP. Sony's made no hardware changes beyond what you can swap yourself. No ACPI changes necessary at all. The laptop simply recognizes the newer procesor, no problem.
