Introduction
A laptop’s serial number is a unique identifier used to identify the device. It can be used to register the laptop with the manufacturer, activate warranties, track stolen devices, and more. This article will explore how to find the serial number of your laptop.
Check the box the laptop came in
The box that the laptop came in should have all the necessary details printed on it, including the serial number. If you still have the box, you can easily find the serial number. The information printed on the box typically includes the model number, product name, and serial number.
To locate the serial number, look for a barcode or a label that has the words “Serial Number” printed on it. The serial number should be printed below this label. If the serial number is not printed on the box, check the paperwork that came with the laptop for the serial number.

Look on the bottom of the laptop
Most laptops have a sticker on the bottom that contains the serial number. This sticker is usually located near the hinges or on the battery compartment. The sticker typically contains the model name, serial number, and other information about the laptop.
To locate the serial number, look for a label that has the words “Serial Number” printed on it. The serial number should be printed below this label. If the serial number is not printed on the sticker, check the paperwork that came with the laptop for the serial number.
Download system information software
There are several pieces of software available that can be used to find the serial number of your laptop. These programs are designed to scan your computer and provide detailed information about the hardware, including the serial number. Some popular programs include AIDA64, CPU-Z, and Speccy.
To download and use one of these programs, visit the manufacturer’s website and download the software. Once the software is installed, launch it and look for the serial number in the System Information tab. The serial number should be listed under the Model or Serial Number section.
Contact the manufacturer
If you are unable to locate the serial number on the laptop or in the paperwork, you may need to contact the manufacturer. You can contact the manufacturer by phone or through their website. When contacting the manufacturer, you will need to provide them with the model number and other information about the laptop so they can locate the serial number.
The manufacturer should be able to provide you with the serial number once they have verified your identity and the information you provided.

Look in the BIOS settings
The Basic Input/Output System (BIOS) is a set of instructions stored in a chip on the motherboard of your laptop. It is responsible for controlling the basic functions of the laptop, such as booting up and shutting down. The BIOS also stores information about the laptop, including the serial number.
To access the BIOS settings, press the power button on your laptop and then press the key indicated on the screen (usually F2 or Delete). Once in the BIOS settings, look for a tab labeled System Information or something similar. The serial number should be listed under this tab.
Use a third-party serial number lookup tool
If all else fails, you can use a third-party serial number lookup tool to find the serial number of your laptop. These tools are designed to search the web for the serial number of your laptop based on the model number. To use one of these tools, simply enter the model number into the search bar and the tool will search the web for the serial number.
These tools are not always reliable, so make sure to double-check the serial number before using it. If the tool returns an incorrect serial number, try another tool or contact the manufacturer.
