I think you can upgrade it, but I highly doubt you'll notice a performance difference over 4GB. 8GB isn't actually useful for much other than future proofing or things you don't do on a laptop (like heavy video editing or CAD work).
I wonder if I can upgrade from 500 GB to 640GB? Would that make it a little faster? I actually am looking at getting a laptop with a smaller screen than 17", as this one is too bulky to carry around. I do not want to spend a bundle. I just need to be able to go to my online live seminars for school without it being interupted by a slow computer. Any suggestions?
Thanks again. Shantel
