Every Lenovo Thinkpad has an identification stamp on the bottom of the laptop. The stamp will have a 7 character serial number usually starting with S/N. It will also have a 7 character model number. As shown in the following image (circled), the model number is used to identify the system and also help you check compatibility for various upgrades. It is a good number to know.


How to use your model number
You can scroll our list of lenovo models to find your model number, usually you only need the first four numbers, in the image below the numbers 2628 are circled. Alternatively we provide a simple filtering tool (red arrow) to quickly find only the model.

When you type in your model number, (see image below) our website filters out all other models, and you can easily find the model you are looking for.
