My mom just got me a new laptop for Christmas, it's a Sony VAIO NR Series, and the model number is VGN-NR140E/S. I have a couple questions; it says on the website that it comes with only 1GB of memory and can handle 2GB. Can someone tell me how many open slots it has for memory, because it doesn't say. All it says is it comes with 2x512MB. Does that mean to get 2GB I would have to buy 2x1GB of memory, or does it have 2 open slots where I could just buy an additional 2x512MB. Also, what determines how much memory it can handle? I would love to have more than 2GB. Is there anything I can upgrade so it can handle more? It has a Pentium Dual Core 1.6GHz processor, which I'm sure is plenty fine for running things like Photoshop. If someone could help me out it would be greatly appreciated. I know it's a little out-dated computer, but we got it for $300 new in the box so we couldn't pass it up. Thanks.
