You’ll need it for everything from registering your product for warranty support to filing an insurance claim or checking for recalls.

Checking the Physical Laptop Itself
If your laptop won’t turn on, or you prefer a more hands-on approach, the serial number is almost always printed on a sticker on the device itself. For most laptops, turn it over and look on the bottom casing. The sticker will list the serial number, often abbreviated as S/N or Serial No. Sometimes, you might find it on the side of the device, or if you have a removable battery, it could be tucked away in the battery compartment.
Looking Within Your System Information
Your Windows operating system also stores this information in an easy-to-access menu. Click the Start button or press the Windows key, and start typing System Information. Open the System Information app. In the window that opens, look through the list on the left under System Summary. Scroll down until you find the System Manufacturer, System Model, and System SKU entries. Your serial number will be listed here as well, providing a clear and official record straight from your laptop’s BIOS.
