okay so you can easily run leopard, all you have to do is get another 256mb ram stick, id suggest just upgrading to 1 gig, your computer takes an ata hard drive, you can get them here
http://www.newegg.com/Product/Produc...889&name=ATA-6 you can get your charger on ebay, just type in powerbook g4, make sure that you specify the size meaning 12in,15,17, because it may actually vary and the charger.
