[QUOTE="pm-r, post: 1788438, member: 175845"] Not 100% and I don't know if there's an official list as to which Apple laptop models are affected. I do know that at least 2009 MacBooks / Pro models and later models use the main battery for PRAM and SMC memory retention rather than having a separate PRAM battery for this purpose, and there is a capacitor to provide power in the event the main battery has been disconnect for short periods of time. The "[I]disconnect for short periods of time[/I]" part won't apply to the OP's case of course: :\ - Patrick ====== [/QUOTE]
