Hello, all. I am currently upgrading my laptop, as I am going away to college next month. I just ordered a new battery online (my old one is pretty much toast

). During my search, I read that more RAM can extend battery life somewhat; I had been wanting more RAM anyway, (because sometimes my lappy is as slow as molasses

) but that was icing on the cake!!
Anyway, I want to know: Can more RAM
really extend battery life? Where can I get good service at a good price (Froogle has been giving me prices
much higher than the manufacturer)?
My laptop is a Toshiba Satellite A65-S1062. It currently has 256mb of non-removable RAM, and I am looking to buy an extra 512mb. Any input?
