Your Dell computer comes with a Service Tag, also known as the Serial Number. Keeping track of this number is useful because it can help you to get warranty service for your computer if it breaks down. There are a few different ways to obtain your Dell computer's serial number.

Your Dell Laptop Serial Number
If your Dell laptop won't power on, then you won't be able to use the Command Prompt method to find your Dell laptop serial number. Instead, you'll need to find the serial number on the outside of the laptop. Where to find this number will depend on the type of Dell laptop you have. If you have a Dell XPS laptop, you'll need to look at the bottom of the laptop and flip open the middle cover to see the model number and serial number. Other Dell laptops typically have the number on a label on the bottom of the computer, usually toward the middle. Older Dell laptop models may have the serial number under the removable laptop battery on the bottom of the laptop.
Your Dell Computer Serial Number

The label also typically contains your computer's original Windows product key.
