Additionally, registering your laptop can help in case your device is lost or stolen, as the serial number can be used to identify your laptop.

With Toshiba laptops, you can try downloading and running the Toshiba Product Information utility if you are unable to find the serial number on the bottom case. This utility should be available for download on the Toshiba website, and it will allow you to retrieve your laptop’s serial number as well as other product information.
