X200s Type: 7469-A18 doesn't appear on Lenovo site.

When I go to Lenovo site and enter my computer type which is 7469-A18 I get there is no such model.. MMmm. That is the model that I have on the sticker at the back and also on the invoice and also googled for it and found it. It displays the 7469 type of computer but doesn't show the A18 model, only other models.
