The functioning

1. Operating temperature: The functioning of the various elements of the laptop (including the processor) can cause an increase in temperature of the laptop, which can sometimes be annoying, especially when the temperature becomes too high for the keyboard. There may be a danger due to overheating, particularly accentuated when the laptop works with the screen closed, because this can prevent proper heat dissipation.
2. Noise: In order to dissipate heat due to the operation of the various elements of the laptop, they are sometimes equipped with cooling devices such as fans, which can create significant discomfort to one’s hearing. The same goes for the engines of rotating hard drives or CD/DVD drives. It is therefore necessary to learn about the noise level of the computer when it is actually running.
