Transferring the Serial Number
When replacing a bottom case, retain the customer’s bottom case until the repair is complete.
Before installing the replacement bottom case, use a ne tip permanent marker to write the
original serial number clearly and legibly in uppercase box letters directly onto the inside of the
new bottom case.
CAUTION: Take great care in deciphering the small typeface of the etched serial number
on the bottom case. You might need a magnifying glass to see it clearly. It is imperative
that you transfer the correct alphanumeric characters. Keep in mind that Apple serial
numbers always use the numbers 1 and 0 instead of the Roman letters “I” and “O.”
Note About Images In This Guide
Because a pre-production model was used for most of the images shown in this guide, you may
notice small dierences in appearance between the image pictured and the computer you are
servicing. However, although the appearance may dier, the steps and sequence are the same
unless noted.
Caution About Ordering Replacement Parts
Caution: Some modules have more than one part number due to dierent product
congurations. Before ordering a replacement part, ALWAYS enter the product serial
number in GSX to nd the compatible part.
