Replacing Components on a Bottom Case
Reassembly Procedure
1. Transfer the plastic wireless panel, and if present, the docking port cover from the old bottom case to
the new bottom case.
2. Install a new Microsoft Product ID label.
3. Transfer the old serial number label, and install a new overlay, or create a new serial number label using
the steps below.
4. Follow the “Reassembly Notes” on page 2-52.
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. The latest
version includes fields for warranty period and manufacturing location. Store the template with other
Word templates on a PC connected to a laser printer.
5. Open a new document based on the serial label template.
6. Enter the information from the old serial label, and then print the new label on plain white paper.
(The new label does not have barcodes.)
7. Carefully cut out the new serial label just inside the border, and then place it into the inner recess
in the bottom case. (The bottom of the label goes toward the front of the case).
8. Make sure all regulatory labels that were on the old bottom case are also on the new bottom case.
9. While holding the paper label in place, attach a serial label overlay into the outer recess. The
overlay covers and protects the serial label.
