Removal and Replacement Procedures
This chapter provides subassembly/module-level removal and replacement
procedures for the Compaq Deskpro Workstation AP250.
After completing all necessary removal and replacement procedures, run the
Compaq Setup and Diagnostics utility to verify that all components are
operating properly.
Serial Number
Provide the computer serial number to Compaq whenever you request
information or order spare parts. The serial number is located on the top corner
of the workstation
1
and also on the rear of the chassis
2
as shown in
Figure 3-1.
For asset control, the serial number is embedded in the EPROM on the system
board. If the system board is replaced with a spare part from Compaq, an
invalid serial number condition will be reported during the Power-On
Self-Test (POST). To clear the condition, reenter the original serial number
through Computer Setup.
NOTE:
POST recognizes the serial number as a valid number if a system board from
another workstation is installed.
