Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) small outline dual inline memory modules (SODIMMs).
SODIMMs
The memory sockets on the system board can be populated with up to two industry-standard SODIMMs.
These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum memory support, you can populate the system board with up to 4GB of memory.
DDR2-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
● industry-standard 200-pin
● unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
● 1.8 volt DDR2-SDRAM SODIMMs
The DDR2-SDRAM SODIMMs must also:
● support CAS latency 5 DDR2 667 Mhz (5-5-5 timing) and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
● contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
● 512Mbit and 1Gbit non-ECC memory technologies
● single-sided and double-sided SODIMMS
● SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not supported
NOTE: The system will not operate properly if you install unsupported SODIMMs.
Refer to the Computer Setup (F10) Utility Guide for information on how to determine the processor bus frequency of a specific computer.
14 Chapter 2 Hardware Upgrades ENWW
Populating SODIMM Sockets
There are two SODIMM sockets on the system board, with one socket per channel. The sockets are labeled DIMM1 and DIMM3. The DIMM1 socket operates in memory channel A. The DIMM3 socket operates in memory channel B.
Figure 2-6 SODIMM Socket Locations
ENWW
Table 2-1 SODIMM Socket Locations
Item Description Socket Color

SODIMM1 socket, Channel A
SODIMM3 socket, Channel B
Black
White
NOTE: A SODIMM must occupy the black DIMM1 socket. Otherwise, the system will display a POST error message indicating that a memory module must be installed in the black socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the SODIMMs are installed.
● The system will operate in single channel mode if the SODIMM sockets are populated in one channel only.
● The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
● The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not equal to the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. If one channel will have more memory than the other, the larger amount should be assigned to channel A.
● In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
Installing Additional Memory 15
Installing SODIMMs
CAUTION: You must disconnect the power cord before adding or removing memory modules.
Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated 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. For more information, refer to Appendix D,
Electrostatic Discharge on page 39 .

D Electrostatic Discharge
A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.
Preventing Electrostatic Damage
To prevent electrostatic damage, observe the following precautions:
● Avoid hand contact by transporting and storing products in static-safe containers.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
● Place parts on a grounded surface before removing them from their containers.
● Avoid touching pins, leads, or circuitry.
● Always be properly grounded when touching a static-sensitive component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:
● Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
● Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.
● Use conductive field service tools.
● Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, contact an HP authorized dealer, reseller, or service provider.
NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or service provider.

Routine Care and Shipping Preparation
Computer Operating Guidelines and RoutineCare
Follow these guidelines to properly set up and care for the computer and monitor:
● 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.
● Never operate the computer with the access 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.
● Turn off the computer before you do either of the following:
◦ Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may discolor or damage the finish.
◦ 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.
40 Appendix E Computer Operating Guidelines, Routine Care and Shipping Preparation ENWW
Optical Drive Precautions
Be sure to observe the following guidelines while operating or cleaning the optical drive.
Operation
● Do not move the drive during operation. This may cause it to malfunction during reading.
● Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit. If the temperature suddenly changes while the drive is on, wait at least one hour before you turn off the power. If you operate the unit immediately, it may malfunction while reading.
● Avoid placing the drive in a location that is subject to high humidity, extreme temperatures, mechanical vibration, or direct sunlight.
Cleaning
● Clean the panel and controls with a soft, dry cloth or a soft cloth lightly moistened with a mild detergent solution. Never spray cleaning fluids directly on the unit.
● Avoid using any type of solvent, such as alcohol or benzene, which may damage the finish.
Safety
If any object or liquid falls into the drive, immediately unplug the computer and have it checked by an authorized HP service provider.
Shipping Preparation
Follow these suggestions when preparing to ship the computer:
1.
Back up the hard drive files on PD discs, tape cartridges, CDs, or diskettes. Be sure that the backup media is not exposed to electrical or magnetic impulses while stored or in transit.
NOTE: The hard drive locks automatically when the system power is turned off.
2.
Remove and store all removable media.
3.
Insert a blank diskette into the diskette drive to protect the drive while in transit. Do not use a diskette on which you have stored or plan to store data.
4.
Turn off the computer and external devices.
5.
Disconnect the power cord from the electrical outlet, then from the computer.
6.
Disconnect the system components and external devices from their power sources, then from the computer.
NOTE: Ensure that all boards are seated properly and secured in the board slots before shipping the computer.
7.
Pack the system components and external devices in their original packing boxes or similar packaging with sufficient packing material to protect them.
