I agree with that, but I still want to say that I would do it if you plan just to use it for school and then come home and charge it. I love to have all my power behind my CPU, and I personaly don't have a laptop but I would set it to use full power causE I know it would last my couple of hours and then I can charge it in the eveneing. The only thing I don't recomend that is if your paying the electric bill
