So I got a new laptop for christmas and I am looking to sorta decorate the cover with stickers of my fav bands and such. Well I bought Transformers thinking the Autobot insignia that came extra with the movie was a sticker, but ended up being a magnet. I really wanna put it on the outer shell of my laptop with some spray adhesive that will hold it in place, but will allow me to take it off with some work. Will sticking a magnet on the outer shell of a laptop do any sort of damage? I keep hearing a magnet will swipe a hard drive or drain power from a computer. Thanks for the help guys!
