This is ridiculous. After I went out and got a new screwdriver to install my 1GB stick of RAM, which I got off of Newegg, it is now not recognized by my computer. So now I'm running with 256MBs of RAM. Beautiful, thank you Apple. http://www.newegg.com/product/product.asp?item=N82E16820145068 This is what I ordered...Crucial Technology 1GB 200-Pin DDR SO-DIMM DDR 333 (PC 2700) Notebook Memory - OEM I thoroughly made sure this was the right RAM, and even people with my same type of computer have said it works on their posting thing.. 1.5 GHz PowerBook G4 15". Anyone know how I can get this to work?
