Lateley I have been using my AAO to listen to OTR radio in the evenings. After a few hours the unit gets EXTREMELY HOT! I mean very hot to the touch! Yesterday after about four hours it shut itself off. :o \n\nDo I have a defective unit, a fan problem - or is this normal for laptops? This is my first laptop as I have always owned desktops.\n\nBTW this happens using the electrical outlet since obviously the battery would never even last as long as three hours.\n\nThanks for any information you can give me.
