How to Check Your Laptop Model and Serial Number
Published: 8 Oct 2026
Knowing your laptop model and serial number is useful when you need drivers, warranty support, repairs, upgrades, or technical help. Every laptop has identifying information that helps you find the exact device you own.
In this tutorial you can check your laptop model and serial number in several simple ways. Windows provides built-in tools, and you can also check the BIOS, Command Prompt, or the physical label on your laptop. Keep your laptop model number and serial number somewhere safe. They can save time when contacting technical support or checking warranty information.
Laptop Model vs. Serial Number: What Is the Difference?
A laptop model number identifies the specific model or product series of a laptop. For example, a manufacturer may sell several versions of the same laptop family with different processors, memory, or storage.
A laptop serial number is a unique identification number assigned to an individual device. Two laptops can have the same model number, but their serial numbers should be different.
| Information | What It Identifies | Common Use |
| Laptop Model | Specific laptop model or series | Drivers, specifications, upgrades |
| Model Number | Exact product/model version | Product identification |
| Serial Number | Individual physical device | Warranty and support |
| Product Number | Manufacturer’s product identifier | Support and parts |
| Service Tag | Manufacturer specific device ID | Technical support |
Things to Know: A model number tells you what type of laptop you have, while a serial number helps identify your individual laptop.
Why Should You Check Your Laptop Model and Serial Number?
Your laptop model and serial number can be important for many everyday technical tasks. Before downloading drivers or buying compatible hardware, knowing your exact laptop model can prevent mistakes.

How to Find Laptop Model and Serial Number in Windows
One of the easiest ways to find laptop model Windows 11 or Windows 10 information is through built-in Windows settings. You do not need to install additional software for basic device information.
The Windows System Information and About sections can provide useful details about your laptop. This makes Windows a convenient option for checking your laptop device information.
Method 1: Check Laptop Model in Windows Settings
Windows Settings is a simple place to start when you want to check laptop details.
- Open Settings.
- Select System.
- Choose About.
- Look under Device specifications.
- Check the available device and model information.
This method is especially useful when you want to check a laptop model in Windows without using technical commands.
Quick Tip: If you are using Windows 11, the System > About section is usually the easiest starting point for basic laptop identification.
Method 2: Use System Information
The Windows System Information tool provides more detailed information about your computer. It can be useful when basic Settings information does not provide everything you need.
Steps to Open System Information
- Press Windows + R.
- Type msinfo32.
- Press Enter.
- Look for a System Manufacturer.
- Find System Model.
- Review other available system information.
This method is useful for laptop hardware information, manufacturer details, and model identification.
Things to Remember: System Information can provide more technical details than the regular Windows Settings page, making it useful for troubleshooting and support.
How to Check Laptop Model and Serial Number Using Command Prompt
Command Prompt is another quick method to check laptop serial numbers in Windows. It can be particularly helpful when you want to retrieve information without opening multiple Settings pages.
You can use a simple command to perform a laptop serial number lookup directly from Windows.
Steps to Check Laptop Serial Number
- Open the Start menu.
- Search for Command Prompt.
- Open it.
- Type the appropriate serial number command.

- Product information
Pro Tip: Copy the displayed information carefully. A single incorrect character can cause problems when you use a serial number for warranty or support requests.
How to Check Laptop Model and Serial Number in BIOS
Another method to find laptop model and serial number is through the BIOS or UEFI firmware. This can be helpful when Windows is not starting correctly.
The exact BIOS interface varies between laptop manufacturers. However, many systems display the laptop model number, serial number, manufacturer, or product information on the main BIOS information screen.
General BIOS Method
- Shut down or restart your laptop.
- Start the laptop again.
- Press the appropriate BIOS/UEFI key during startup.
- Look for System Information, Main, or a similar section.

Check the Physical Laptop Label
If your laptop is not turning on, you can often perform laptop identification by checking the physical device.
Look underneath the laptop for a sticker, printed label, engraved information, or manufacturer’s identification panel. Depending on the laptop, you may find the model, serial number, product number, or service tag.
Some laptops place this information inside the battery compartment or another accessible area. Information you may find on the label are:
| Label | Meaning |
| Model | Laptop model or series |
| S/N | Serial number |
| Serial No. | Individual device number |
| Product No. | Product identification number |
| Service Tag | Manufacturer support identifier |
Suggestion: Take a clear photo of the label before it becomes difficult to read. This can be useful for future repairs and support.
Laptop Model Number, Product Number, and Service Tag
Laptop manufacturers can use different names for identifying information. This can sometimes make laptop model lookups confusing.
A model number, product number, and service tag are not always the same thing. Their purpose depends on the manufacturer and laptop series. What should you look for?
When checking your laptop, look for terms such as:
- Model
- Model Number
- Product Number
- Serial Number
- Serial No.
- Service Tag
- System Model
Important Note: Do not assume that every number printed on your laptop is the serial number. Look specifically for labels such as S/N, Serial Number, or Serial No.
