That little sticker on your laptop might seem unimportant, but the serial number it holds is its unique fingerprint. Knowing how to find it is a small piece of knowledge that can save you a great deal of time and hassle. Whether you need to register for warranty support, check for service recalls, or insure your device, having this number handy is essential.
Checking the Physical Laptop

This label usually includes the serial number (often abbreviated as S/N or Serial No.), along with the product name and model number. If it’s not on the bottom, check inside the battery compartment after safely removing the battery. Some manufacturers also print it on the original packaging or the included warranty card.
Using Your Computer’s Operating System

On a Windows PC, open the Command Prompt and type wmic bios get serialnumber then press Enter. The number will appear on the screen.
