Every Apple Powerbook I have owned has possessed a button - either under the keyboard (on motherboard), or on the back panel of the unit. This is the first one that I have ever seen that seems not to be equipped with one. There seems to be no way of lifting the keyboard to gain access to the motherboard and there are no buttons on the case itself. The manual that comes with the machine makes no mention of such a button (it did with previous machines). It does mention a new three-finger procedure that I have not heard of before (Command/Control/Power) to reset the system, but I can't thing that this does the same as pushing and holding the PMU button. Anyone have any insight on this one? jg
