1] Find it under the laptop

Every manufacturer put a sticker under the laptop containing the service tag. It can be a combination of English letters or digits and letters. You may find the service tag as S/N, which represents Serial Number. In other words, the service tag and serial number are the same, and if you have already got the serial number, there is no need to look for the service tag.

If the sticker under your laptop has been damaged for some reason, you can use the Command Prompt and Windows PowerShell to get the same job done. A simple command can get you the service tag or serial number that you are looking for.

2] Find Service tag using Windows PowerShell

To get started, press Win+X to open the menu and choose Windows PowerShell. Then, enter the following command-

wmic bios get serialnumber

It shows the result immediately. If needed, you can copy the serial number from there and use it in the future.

Says Jose Deras, you can also use this:

Get-WmiObject Win32_BIOS SerialNumber | select SerialNumber
