Serial Number Locations
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.
