The laptop fan spun for a while when I turned on the laptop and then stopped spinning, and it still beeped after I turned on the laptop to the desktop, what should I do? What should I do? I'm not sure how to do this. Only when the laptop fan turned on for a while, it did not turn, and when the laptop was turned on to the desktop, it still beeped, according to you, the beeping did not come from the fan? In fact, I think this does not make sense, the machine if there is no fan, can not be opened for a long time, he usually automatically power off, the temperature is too high a lot of protection features! This sound is generally issued from the hard disk, if the hardware is bad you have to find the manufacturer to repair, there is also a possibility of poisoning!!!! Hard disk reading data is too fierce is also a loud sound
