Hi All, I have a Powerbook G4 1.5 w/ 1GB of RAM and the stock 80GB HD. I've run this puppy pretty hard for a couple of years now, and it's lately started to lag a bit - perfectly natural. I was considering buying a new notebook but I've decided to wait until after Leopard comes. So my question is: 1) How do I determine the max RAM I can put in this machine? 2) Are there are specific specs I need to be concerned with when swapping out the Hard Drive? Any type, size limitations, speed limitations, etc. I'd love a little input as to how I find out this info. I think instead of taking the notebook plunge now, I'm going to put a nice new hard drive in this one and possibly bump up the RAM a little more if it will take it. Thanks!
