To determine if a notebook, convertible, or tablet is configured for use with a pen, and the type of pen, obtain the model number (usually a ten digit number) and use it to search for the configuration on Lenovo's Product Specifications Reference (PSREF) website.
Once the model of the product or the name of the product has been provided, scroll right to look for a column named "Pen".
*Please note that in ThinkVantage products, this information is listed in the Touchscreen/Digitizer Pen/battery column.
Please note that some products support more than one type of pen.
