So from personal experience, I have a good sleep when the laptop is placed away from my head, or when the thing is in hibernation, but when I have my laptop running, near my head, I wake up all groggy. So what is the cause of this? If I slept with the laptop running near my head, would it give me a brain tumor? So what I am saying is, if I sleep 8 hours, without the laptop near my head, it felt like I slept 8 hours. With it near my head, it felt like I slept 6 hours, and I would fall asleep in class the next morning. So what is the cause of all this, and is it a conspiracy that if you sleep near a laptop, or computer, while it is on, that it would mess up your brain? I want to know this, because I tend to put the laptop near my bed, and while I am watching videos, I sometimes fall asleep, with the laptop running. Oh I am using an ASUS f50sv by the way.
