To find the serial number of your laptop, you can use one of the following methods:

1. Check the bottom of the laptop: Many laptops have a sticker on the bottom casing that displays the serial number along with other identifying information. Look for a label or sticker containing alphanumeric characters. The serial number may also be accompanied by a barcode.

The method for accessing these settings varies depending on the laptop manufacturer and model. Typically, you need to press a specific key (e.g., F2, F10, Del) during startup to enter the BIOS or UEFI. Once in the BIOS or UEFI settings, you can usually find the serial number listed under system information or a similar category.
