Technician Notes
!
WARNING:
Only authorized technicians trained by Compaq should attempt to repair this
equipment. All troubleshooting and repair procedures are detailed to allow only
subassembly/module level repair. Because of the complexity of the individual boards and
subassemblies, no one should attempt to make repairs at the component level or to make
modifications to any printed wiring board. Improper repairs can create a safety hazard. Any
indications of component replacement or printed wiring board modifications may void any
warranty.
!
WARNING:
To reduce the risk of electric shock or damage to the equipment:
Do not disable the power grounding plug. The grounding plug is an important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
Disconnect the power from the computer by unplugging the power cord either from the electrical
outlet or the computer.
CAUTION:
The computer is designed to be electrically grounded. To ensure proper operation, plug
the AC power cord into a properly grounded AC outlet only.

Compaq Deskpro EP Series of Personal Computers
1-2 Product Description
1.1 Model Overview

models. They contain the unique, flexible Compaq ATX chassis, which allows you to
easily reconfigure the unit as a minitower by (1) removing the drives from the computer,
(2) standing the unit on its side, (3) rotating the drives and bezel blanks 90 degrees, then
(4) reinserting the drives into the drive bays.
The Compaq Deskpro EP Series, Intel 440BX chipset models will be referred to
in this MSG as 440BX.
The Compaq Deskpro EP Series, Intel 810 chipset models will be referred to in
this MSG as 810 or Intel 810.
The Compaq Deskpro EP Series, Intel 810e chipset models will be referred to in
this MSG as 810e or Intel 810e.
Compaq Deskpro EP Series of Personal Computers 1-3
1.2 System Design
! Desktop models of the Compaq Deskpro EP Series of Personal Computers use an
innovative chassis to house the removable system board, expansion boards, power
supply, and mass storage devices.
!
Internal components are accessible when the access panel is removed.
!
The front bezel is a multi-part assembly that attaches to the chassis with release
latches. Attached to the back of the front bezel is a subpanel that holds the bezel
blanks.
! The system board may be removed from the chassis after the access panel is
removed. Details of the disassembly procedure are found in Chapter 4, “Removal
and Replacement Procedures.”
! The drive bays are located in the front of the chassis; there are two 3.5-inch drive
bays for internal hard drives and three 5.25-inch drive bays for accessible mass
storage.
!
The chassis design allows drive installation without the use of rails. Guide screws
installed on each side of the drive ensures its proper alignment within the drive
bay. Extra guide screws are provided in the front of the chassis.
! The desktop model of this computer may be converted to a minitower
configuration. See Chapter 4, “Removal and Replacement Procedures,” for
additional information and instructions.
Detailed descriptions of the system components are presented in the sections that follow.

1.5 Serial 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
.
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.
