Toshiba Satellite A300 Laptop Review

I do not know much about computers, so I did a lot of research - asking friends, looking up models online, etc. - and ended up buying this one, and planned to use it for university. The whole plan of taking notes on my laptop in class went down the drain when I realized how heavy this was to carry around all day, and how uncomfortable it was to have to carry it in its special little bag, because it was too big to fit into my backpack, which seemed to be what everyone else could do. For the most part, it stayed home like a desktop would, but I have not had technical problems; the machine has run smoothly for about three years now. The only complaint I have would be that it overheats from time to time. It gets so hot sometimes that I'm afraid of it blowing up. I've tried using one of those fans that you place under a laptop to cool it down, but it did not work too well; the problem remains.
