Compaq EX Series, EXS Series manual Serial Number Location

1.2Serial Number Location

The serial number and model information label is located on the access panel of the unit 1. A second barcode label is located on the rear of the unit 2.

For the purpose of AssetControl, the serial number is embedded in CMOS and in the EEPROM on the system board and may be accessed through Diagnostics for Windows.

If the system board is replaced with a spare part from Compaq, the invalid serial number condition will be recognized during POST. The original serial number must then be reentered through Computer Setup. Refer to the Software Reference Guide for more information.

CAUTION: A system board borrowed from another computer is recognized as a valid serial number and will create a mismatch between the serial number label and the electronic serial number.

The computer serial number should be provided to Compaq when requesting information or ordering spare parts.
