• I/O Logic Board: This serial number label is viewable from the opening for the PC Card slots. You don’t need to disassemble the PowerBook. Gently push in the PC Card slot doors and look inside the opening. You should see the serial number/bar code label. You may need to use a small flashlight to see the lettering on the label.

The ID codes are printed in one of two ways:

– Either the next-to-last three characters in the serial number. For example, if the serial number is *CK8xxxxxyyyx* then the ID code would be “yyy”.

– Or within the last 5 characters of the serial number. For example, if the serial number is *KC8xxxxxxyyyxx* then the ID code would be “yyy”. This type of serial number label has Singapore printed directly after the serial number.
