Because of its function, the reset key is generally hidden and difficult to touch. The RESET key is a key position in the host computer, notebook computer, smart phone, smart PDA or other electronic products, also called the reset key, that is, reset. The reset key of desktop computer is generally near the start key on the chassis, and the reset key of notebook computer is at the top of the keyboard. Its function is to press this key when the electronic product or computer crashes, so that it can be restarted without power failure.

Working principle of reset key:
The reset key is started after clearing the current CPU and running data. It does not involve power failure.
The reset key appears less and less on the computer. In the early computer system, because the software and hardware were not very mature, the system often reacted badly and crashed. When pressing Ctrl+Alt+Delete is invalid, you need to press the reset key to restart. RESET is commonly known as the cold start key, which is used for instant restart.
With the computer technology becoming more and more mature and the operating system becoming more and more stable, the function of the RESET key becomes less and less obvious, and many new computers or server systems simply cancel this key.
The difference between forced shutdown and restart and pressing the reset button lies in whether the computer is turned off during this process. After pressing the reset button directly, the hardware of the computer host does not gasp at all (there is no power failure), and the impact on the computer in terms of current will be reduced, so the damage to the computer will be less. So it would be better to press the reset button in the case of a crash. Forced shutdown and restart, in some cases, can help us automatically repair some problems caused by hardware.
