That little serial number on your laptop is more important than it seems. You might need it to register your device for warranty support, check if a repair part is compatible, or even prove ownership if it’s ever lost or stolen. But when you need it, finding that specific string of letters and numbers can feel like a scavenger hunt.
Don’t worry, you don’t have to be a tech expert to locate it. There are several simple ways to find your laptop’s serial number, whether you can turn it on or not. We’ll guide you through the easiest methods so you can get the information you need quickly.
Check the Physical Laptop First
Before you even press the power button, take a moment to look at the laptop itself. The serial number is often printed on a sticker located on the bottom of the device. If you have a removable battery, you might find the sticker underneath it. For some models, you could also check around the screen hinge or inside the battery compartment. Look for a label that says “Serial Number,” “S/N,” or “Serial No.”
Use a Simple Command on Your Computer
If your laptop is on and working, this is often the fastest way. Simply press the Windows key + R to open the Run dialog box. Type cmd and press Enter to open the Command Prompt. In the black window that appears, type the following command and press Enter:

Your serial number will appear right on the screen. This method pulls the information directly from your system’s BIOS, so it’s very reliable.
Find It in Your System Information
Another easy way is through the System Information panel. You can get there by typing “System Information” into your Windows search bar and opening the app. Once it loads, look through the list of items on the right side for “System Serial Number.” This screen also provides other useful details about your machine’s hardware.
Why Your Serial Number is So Useful
Having this number handy is a great habit. It’s your key to getting technical support from the manufacturer, especially if your laptop is still under warranty. When you need to order a specific replacement part, the serial number ensures you get the right component for your exact model. It also serves as a unique identifier for your device, which can be important for insurance purposes or if you need to report it missing.
With these simple tips, you should be able to locate your laptop’s serial number in just a minute or two. It’s a small piece of information that can save you a lot of time and hassle later on.
