It should run Linux Mint just fine. Look back where Pudly and I were discussing it with DoggyDaddy. I posted a link to a Live USB creator, which will let you create a boot USB drive to run Linux Mint (or another distro) to test it out, no installation required. If you don't like it, you're only out a bit of time. The laptop I'm typing this up on is an old Gateway gaming laptop with 4MB of RAM. It's a little newer than what you have, as it came with Vista. I've been running it with Linux Mint the last couple of years and I've been very happy with it.
I see it, (post # 76) but I'll have to get a bigger thumb drive (8 gig I see) then I'll give it a try.
I have an external hard drive also as a backup.
I like it that I can try it first without changing my present system.
