If not, what PB is it for? No, that is for older PowerBook 1XX machines. I don't know if it would work with a PB100. It will work with all other PB1XX except the color machines (PB165c and PB180c) which require a 3 A PS. I believe at least one of the QuickTake cameras also use this supply. There may be some other Apple products which use it too. The specs I have only list it as 36 W (which the 15W of the M5140 is well below). I have used the power supplies (Auto and AC) for a G3 (3500) with a Duo 280C. I suspect they would work as well for a PB2300 -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting "I'm a designated driver on the Information Super Highway"
