rockonn91 is right! If you dont believe what any of us is telling you, then dont do it. But I can assure you the magnet wont erase your hard drive by simply putting your laptop on top of the amp! I have had my laptop sitting on top of one of my Crate 4x12 cabinets many times looking at sheet music. Never had any issues. And those are 4 BIG magnets on 4 speakers!
