My Aunt gave me her old laptop, which works well, but the top will not stay up. It makes it almost impossible to use. My mother bought a used laptop, which is beautiful, but the hard drive is crashing, and so it's almost completely unusable. I was wondering if it would be possible to swap out the hardrives? One is a Sony and the other is a Toshiba. If it is possible, how do you do it? Any advise would be GREATLY appreciated!
