It is normal for the laptop to have sound. The reason why there is sound may be because the notebook has not been used for a long time, or the hard drive is overloaded due to frequent downloading of data. It may also be caused by the fan running and the hard drive screws being loose.

This will cause the hard drive motor to fatigue and produce abnormal noise, but this abnormal noise will not last for a long time.
Abnormal noise in the notebook may also be caused by the running fan. There are fans inside the notebook for heat dissipation. The main function of the fan is to reduce the temperature inside the notebook. However, it should be noted that when the sound of the fan is very loud, it may be because the fan is faulty. In this case, the fan speed should be checked and the fan should be replaced if necessary.
If there is an obvious "sizzling" sound when opening a file, opening a game, or copying a file in your laptop, this is probably because the laptop's hard drive is broken or the hard drive is fixed. If the screws are loose, you need to back up the files in time and replace the hard drive, or tighten the screws.
