I am going to replace my ram and upgrade to 8 g,yes this is the newer model with the access at the back. My question is do i need to back up pictures and what not on a memory stick. I figured i do but some one said i don't.
No, your data is stored on your hard drive. Flip it over, pop the case, replace the memory modules and get back on the road. 5 minute job at the most.
