How to find compatible parts for Lenovo PCs

Solution 1: Use Lenovo SmartFind website

You can use Lenovo SmartFind to find compatible accessories easily. All you need to know is the machine “type number“.

For example, a ThinkPad T580 may have a machine type of 20L9 or 20LA. You can find the type number by running the command: wmic baseboard get product and note the first four letters/numbers.

Solution 2: Use website

You can also use the link below and replace XXXXXXXXXX with the model number e.g 20J6003GMX. This will take you directly to all compatible parts for that particular type of computer you have.

If that doesn’t work, you can go to and search for any PC.

Solution 3: Use the OCM spreadsheet

Although this method might not always be up to date, you can use a spreadsheet called “Accessories and Options Compatibility Matrix (OCM)” from Lenovo.

It is basically a huge spreadsheet document that contains a matrix of all compatible products.

It is not very user friendly, but this table includes detailed info and comments from Lenovo. Great for IT employees that need to know specifications, FRU, and so on…
