Removing and Installing Memory

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3­SDRAM) small outline dual inline memory modules (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 16 GB of memory.
For proper system operation, the SODIMMs must be:
industry-standard 204-pin
unbuffered non-ECC PC3-10600 DDR3-1600 MHz-compliant
1.5 volt DDR3-SDRAM SODIMMs
The DDR3-SDRAM SODIMMs must also:
support CAS latency 9 DDR3 1600 MHz (9-9-9 timing)
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
8 Chapter 2 Hardware Repair and Upgrade
In addition, the computer supports:
512-Mbit, 1-Gbit, and 2-Gbit 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.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the SODIMMs are installed. Refer to the following table to identify the SODIMM channel locations.
Table 2-1 Identifying SODIMM Locations
Location System Board Label Channel
Lower Socket DIMM0 Channel B
Upper Socket DIMM0 Channel A
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.
There are two memory sockets on the system board located behind the memory access panel. To remove or install memory modules:
1. Remove all removable media, such as compact discs or USB flash drives, from the computer.
2. Turn off the computer properly through the operating system, then turn off any external devices.
3. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the
power to drain 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.
4. Remove/disengage any security devices that prohibit opening the computer.
5. Place the computer face down on a soft flat surface. HP recommends that you set down a blanket,
towel, or other soft cloth to protect the screen surface from scratches or other damage.

A 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.

B Computer Operating Guidelines,
Routine Care and Shipping Preparation

Computer Operating Guidelines and Routine Care

Follow these guidelines to properly set up and care for 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 to permit the required airflow.
Never restrict the airflow into the computer by blocking any vents or air intakes.
Never operate the computer with any of the access panels removed.
Do not place computers so near each other that they are subject to each other’s recirculated 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 with any type of material.
Install or enable power management functions of the operating system or other software, including
sleep states.
When cleaning the computer turn off power to the computer and unplug the power cord before
you do any 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.
Do not use cleaners that contain any petroleum based materials such as benzene, thinner, or
any volatile substance to clean the screen or cabinet. These chemicals may damage the computer.
Wipe the screen with a soft, clean antistatic cloth. For more difficult cleaning situations, use a
50/50 mix of water and Isopropyl alcohol. Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface. Never spray the cleaner directly on the screen surface. It may run behind the bezel and damage the electronics.
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.
34 Appendix B Computer Operating Guidelines, Routine Care and Shipping Preparation

Optical Disc Drive Precautions

Be sure to observe the following guidelines while operating or cleaning the optical disc drive.
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.
CAUTION: 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:
