The salesman who I spoke to about the laptop said it was upgradeable to 128GB memory, however, he said Dell couldn't do it. When I called again they suggested I should wait until I get the computer and then would tell me how to upgrade. When I said let me buy two 64GB sticks, he said no that I would lose the warranty as my laptop is coming this Saturday. I called Dell back and couldn't get a straight answer. Since I didn't have the computer in my hands they wouldn't let me talk to tech support. Would anyone know anything about this?
