PATA Device Information
The USDT model is the only product that supports a PATA optical drive. No PATA drives are supported
on any other model.
ATA SMART Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.
Hard Drive Capacities
The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be
properly accessed by the operating system. A single hard drive may therefore be subdivided into a
number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the operating
system may differ from that marked on the hard drive or listed in the computer specification. Drive size
calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes
to the base 2.

5 Identifying the Chassis, Routine Care,
and Disassembly Preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the

Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The following table shows that:
Different activities generate different amounts of static electricity.
Static electricity increases as humidity decreases.

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
sides of the computer and above the monitor to permit the required airflow.
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
●
●
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.
Never operate the computer with the cover or side panel removed.
●
●
Do not stack computers on top of each other or place computers so near each other that they are
subject to each other’s re-circulated or preheated air.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
be provided on the enclosure, and the same operating guidelines listed above will still apply.
●
Keep liquids away from the computer and keyboard.
●
●
●
Never cover the ventilation slots on the monitor with any type of material.
Install or enable power management functions of the operating system or other software, including
sleep states.

Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) dual inline memory modules (DIMMs).
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 4 GB of memory configured in a high-
performing dual channel mode.
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
●
●
●
unbuffered, PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
●
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
512Mbit and 1Gbit non-ECC memory technologies
single-sided and double-sided DIMMs
●
●
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.

The system will automatically operate in single channel mode or dual channel mode, depending on how
the DIMMs are installed.
The system will operate in a higher-performing dual channel mode if like-sized DIMMs of equal
capacity are populated in one or both pairs of sockets. For example, if the Channel A XMM1 socket
and Channel B XMM2 socket (the two black sockets) both have 1024MB DIMMs installed, the
system will operate in dual channel mode. If this system had two additional DIMMs added into the
blue sockets, they could be a pair of 512MBor 1024MB DIMMs and the system would still operate
in dual channel mode. For purposes of “like sizes,” a single-sided 512MB DIMM and a double-sided
512MB DIMM would not be the same size because they have different numbers of memory chips
on them.
●
The system will operate in single channel mode if the DIMMs are populated in any other supported
configuration. Supported configurations consist of any combination of one, two, three, or four
DIMMs as long as socket XMM1 is populated before socket XMM3 in Channel A, and socket XMM2
is populated before socket XMM4 in Channel B.
●
If a single DIMM is installed, it must be installed in the XMM1 socket.
●
●
In either mode, the maximum operational speed is determined by the slowest DIMM in the system.
Memory 37
Download from Www.Somanuals.com. All Manuals Search And Download.
CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it
is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. Refer to Electrostatic Discharge Information on page 19 for more information.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
3. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket. A DIMM must occupy the black XMM1 socket.
NOTE: For maximum performance, populate the sockets so that the memory capacity is spread
as equally as possible between Channel A and Channel B.
4. Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted and
properly seated. The DIMM must be pushed all the way down into the socket and sit evenly in the
socket to avoid memory corruption. Make sure the latches are in the closed position (3).
5. Repeat steps 3 and 4 for any additional modules that you want to install.
NOTE: The computer automatically recognizes the additional memory when turned on.
To reassemble the computer, reverse the removal procedure.
