38 Chapter 3 Hardware repair and upgrade
Populating SODIMM sockets
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.
Location
System board label
SODIMM1
Channel
Lower Socket
Upper Socket
Channel B
Channel A
SODIMM3
●
●
The system will operate in single channel mode if the SODIMM sockets are populated in one channel
only.
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.
●
●
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.
In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
Installing SODIMMs
There are two memory sockets on the system board. To remove or install memory modules:
1. Remove all removable media, such as optical 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 AC power cord from the AC outlet and disconnect any external devices.
CAUTION: You must disconnect the AC 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,

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.
Preventing electrostatic damage 61
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 in) 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 AC 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.
62 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 ODD.
●
●
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.
