Installing a New Serial Number Label
Download the latest version of the serial number label template (Microsoft Word format) from the
Partnership Web site (see page vii) under Support/Service in Technical Support Information, or from
http://www.mcd.hp.com. Store it with other Word templates on a PC connected to a laser printer. The
latest version includes fields for warranty period and manufacturing location.
 1. Open a new document based on the serial label template.
 2. Enter the information from the old serial label, and print the new label on plain white paper. The
new label does not have barcodes.
 3. Carefully cut out the new serial label just inside the border and place it into the inner recess in the
bottom case. The bottom of the label goes toward the front of the case.
 4. While holding the paper label in place, attach a serial label overlay into the outer recess. It covers
and protects the serial label.
