My Loading Screen is Stuck at 99%

As a general rule, laptops take more powerful components to achieve the same or similar results than hardware on desktops. It's not that one can't have a successful gaming experience on laptops, it just often takes higher end components and a decent cooling system to get there. You don't have to go quite as far as a Predator Helios 300, now that's kind of going from one extreme to another, but many low- to mid-range systems are just not going to deliver what the player wants even by TS3's 2009 standards.

But just to be clear, none of this really has anything to do with not retreating from the Main Menu and data getting stuck in RAM in between gaming sessions. That's can and will, for many, happen anyway as it's a program design flaw and not dependent on hardware.
