My Dell Laptop mousepad stopped working about 4 weeks ago out of nowhere. And Ive tried everything that was recommended for my situation, none of it worked. For some reason every 7 days when my laptop is shutoff and not charged at all, the mousepad works for about 2 minutes then stops working again, I don't know why that's happening and it's getting me pretty mad because I don't know what else to do. Please, does somebody know what's wrong with my laptop and what I can do to fix it??
