I bought this laptop used, It’s an IBM ThinkPad, model : Lenovo T60. it says it has 973MB of free space on it, which is nothing. but the problem is that there is nothing on the computer. What do i do? Is it possible for your physical memmory to delete?

I heard that the sony vaio heats up honestly quickly, is it really worth the extremely high price? What do you guys suggest?
