A computer's Serial Number (SN) is a unique identifier assigned to each individual computer by its manufacturer. This number is used for identification and tracking purposes, especially for warranty and support services.

You can find the Serial Number of a computer in several ways:

1. On the physical hardware: Most computers have a sticker somewhere on the chassis that lists the serial number. For laptops, this is typically on the bottom or inside the battery compartment. For desktops, it's usually on the back or sides of the tower.
2. Through the operating system: For Windows systems, you can retrieve the serial number by opening the Command Prompt and typing the command 'wmic bios get serialnumber'.
3. On the original packaging: If you have kept the original box in which the computer came, the serial number is usually printed on the packaging.

These methods should help you locate the serial number of your computer. If you are unable to find it through these means, please contact our customer support, we can also provide assistance in identifying your computer's serial number.
