Lenovo provides the information in the Product Specifi cations Reference (PSREF) withdrawn product books on an "AS-IS" basis. Because the 
actual products have been withdrawn from marketing, the information in these withdrawn product books is no longer maintained or updated. The 
referenced footnote numbering may not correspond with the listed footnotes.
