Small Form-Factor Desktop, Small Desktop, and Small Mini-Tower
Systems — Removing and Replacing Parts: Dell™ OptiPlex™ GX150 Service
Manual
This section provides procedures for removing and replacing the
components, assemblies, and subassemblies in the Dell OptiPlex small form-factor desktop,
small desktop, and small mini-tower chassis GX150 systems. Unless otherwise noted, each
procedure assumes that the following conditions exist:
The GX150 chassis is primarily a tool-less one, but certain
procedures (such as removing drive bracket rails and removing the control panel) require
the use of one or more of the following tools:
- Small flat-blade screwdriver
- #1 and #2 Phillips-head screwdrivers
- An 8-inch, #2 Phillips-head screwdriver
Also, Dell recommends that you use a wrist grounding strap as
explained in "Precautionary Measures."
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.
 |
CAUTION: Follow the "Safety Instructions" in the
Setup and Quick Reference Guide to help protect your computer from damage and to ensure your own personal safety. |
Before you perform any procedure in this section, read the following
caution for your personal safety and to prevent damage to the system from electrostatic
discharge (ESD).
|
CAUTION: FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE
EQUIPMENT
Before you start to work on the system, perform the following steps in the sequence
listed:
- Perform an orderly
computer shutdown using the operating system menu.
- Turn off the computer and all attached devices.
- Disconnect the computer and devices from their AC power sources.
Also, disconnect any telephone or telecommunication lines from the computer. Doing so
reduces the potential for personal injury or shock.
- If you are disconnecting a device from the computer or are removing a
component from the system board, wait 15 to 30 seconds after disconnecting the computer
from AC power before disconnecting the device or removing the component to avoid possible
damage to the system board.
- Verify that the auxiliary power indicator on the system board is not
on. If it is on, you may need to wait 15 to 30 seconds for it to go out (see "System Board Components" for the location of this indicator).
- Wear a wrist grounding strap, and clip it to an unpainted metal
surface, such as the padlock ring on the back of the chassis. If a wrist grounding strap
is not available, touch an unpainted metal surface on the back of the computer or on the
computer chassis, such as the power supply, to discharge static charge from your body
before touching anything inside the computer. While you work, periodically touch an
unpainted metal surface on the computer chassis to dissipate static electricity that might
harm internal components.
In addition, take note of the following safety guideline when
appropriate:
- Handle components and cards with care. Do not touch the components or
contacts on a card. Hold a card by it edges or by its metal mounting bracket. Hold a
component such as a microprocessor by its edges, not by its pins.
|
 |
NOTE: On the small form-factor and small desktop
systems, remove the stand before you open the computer cover. On the small mini-tower
system, place the system on its side before you open the cover. |
To open the computer cover, perform the following steps:
- Turn off your computer and peripherals, and observe the caution for
your personal safety and protection of your equipment described in "Precautionary Measures."
- If you have installed a padlock through the padlock ring on the back
panel, remove the padlock.
- Open the computer cover as follows:
NOTICE: Do not open the cover if the system is on the edge of a desk
or table. Doing so may cause the system to tip over and fall. Make sure that the system is
situated so that there is at least 12 inches of desk- or table-top for the cover to rest
on.
- Press the two release buttons until the cover is free to swing up.
- Raise the back of the cover, and pivot it toward the front of the
system.

optical-drive data cable and/or the hard drive data cable from the system board and open
the cover to a 90-degree angle.
Opening the Small Mini-Tower System to a 45-Degree Angle
Closing the Computer Cover
To close the computer cover, perform the following steps:
- Check all cable connections, especially those that might have come
loose during your work. Fold cables out of the way so that they do not catch on the
computer cover. Make sure cables are not routed over the drive cage—they will prevent
the cover from closing properly.
- Check to see that no tools or extra parts (including screws) are left
inside the computer's chassis.
- In the small mini-tower system, close the cover to a 45-degree angle
and connect the optical-drive data cable and hard drive data cable to the system
board.
- Close the computer cover by pivoting the cover down toward the back
of the chassis and into position. Make sure that the release buttons click into place.
- If you are using a padlock to secure your system, reinstall the
padlock.

- Disconnect the power and interface cables from the drive.
- For the small form-factor system, press in on the tabs on each side
of the bracket, slide the drive toward the I/O panel, and remove the drive from the
chassis.
For the small desktop and small mini-tower systems, press in on the
tabs on each side of the bracket, and slide it up and out.
- If your replacement hard drive does not have the bracket rails
attached, remove the four screws holding the bracket rails to the hard drive.
NOTICE: To avoid possibly damaging the drive by ESD, ground
yourself by touching an unpainted metal surface on the back of the chassis.
NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage
the drive. Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.
- If necessary, attach the bracket rails to the new hard drive by
aligning the four screw holes of the drive and bracket and then inserting and tightening
the screws that came with your upgrade kit.
- Reinstall the hard-drive bracket in the chassis by gently sliding the
bracket into place until you hear it securely click.
- On the small desktop system, replace the hard-drive shroud.
- Connect a power cable to the power input connector on the back of the
drive, and connect one of the device connectors on the EIDE cable
to the 40-pin interface connector on the back of the hard drive.
- Check all connectors to be certain that they are properly cabled and
firmly seated.
NOTICE: To avoid possible damage to the system, you must match
the colored stripe on the EIDE interface cable with pin 1 on the drive's interface
connector and with the EIDE interface connector (labeled IDE1) on the system board.
To locate EIDE connector 1 (IDE1) on the system board, see "System
Board Components."

- Close the computer cover.
- If the drive you just installed is the primary drive, insert a
bootable system diskette disk into the diskette drive.
- Turn on the computer.
- Enter system setup and update the appropriate Primary Drive
option, 0 or 1.
See the User's Guide for complete information on system setup.
- Reset the chassis intrusion detector.
- Restart the system.
- Partition and logically format the system's hard drive before
proceeding to the next step.
For partition and format instructions, refer to the documentation
that came with the operating system.
| |
NOTE: On systems with hard drives
larger than 2 GB, create a primary partition of 2 GB and divide the remaining capacity
into partitions of 2 GB or less. For example, a system with a 2.5-GB hard drive would have
a primary partition of 2 GB (drive C) and a second partition of 500 MB (drive D). Hard
drives must be partitioned this way because MS-DOS®-based operating systems (including
Microsoft® Windows NT®, when using a FAT16 file system) do not support drive partitions
larger than 2 GB. |
- Test the hard drive by running the Dell Diagnostics.
See "Solving Problems" in the User's Guide for complete information.
- If the drive you just installed is the primary drive, install the
operating system on the hard drive.
For instructions, refer to the documentation that came with the operating system.
