3 Routine care, SATA drive guidelines, 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 system

board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.

Electrostatic discharge information

A sudden discharge of static electricity from your nger 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 aected 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 how humidity aects the electrostatic voltage levels generated by dierent activities. A product can be degraded by 700 volts.

●

Dierent activities generate dierent amounts of static electricity.

●

Static electricity increases as humidity decreases.

Electrostatic discharge information 11

Preventing electrostatic damage to equipment

Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories.

●

To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.

●

Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging.

●

Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.

●

Place items on a grounded surface before removing them from their containers.

●

Always be properly grounded when touching a sensitive component or assembly.

●

Avoid contact with pins, leads, or circuitry.

●

Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.

Personal grounding methods and equipment

Use the following equipment to prevent static electricity damage to equipment:

●

Wrist straps are exible straps with a maximum of one-megohm ± 10% resistance in the ground cords. To provide proper ground, a strap must be worn snugly against bare skin. The ground cord must be connected to the banana plug connector on the grounding mat or workstation and t snugly into it.

●

Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with most types of shoes or boots. On conductive oors or dissipative oor mats, use them on both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

Antistatic plastic

Carbon-loaded plastic

Metallized laminate

Grounding the work area

To prevent static damage at the work area, observe the following precautions:

●

Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and use properly grounded tools and equipment.

●

Use static-dissipative mats, foot straps, or air ionizers to give added protection.

●

Handle electrostatic-sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free work areas.

●

Turn o power and input signals before inserting and removing connectors or test equipment.

1,500

7,500

15,000

●

Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.

●

Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.

●

Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

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 airow.

●

Never restrict the airow 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 airow.

●

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 airow. 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.

Operating guidelines 13

●

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.

Routine care

General cleaning safety precautions

1. Never use solvents or ammable solutions to clean the computer.

2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use

the cloth on the component.

3. Always unplug the computer when cleaning with liquids or damp cloths.

4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.

5. Disconnect the keyboard before cleaning it.

6. Wear safety glasses equipped with side shields when cleaning the keyboard.

Cleaning the computer case

Follow all safety precautions in General cleaning safety precautions on page 14 before cleaning the computer.

To clean the computer case, follow the procedures described below:

●

To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.

●

For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping the surface with a cloth or swab dampened with clear water.

●

For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed; alcohol will evaporate quickly without leaving a residue.

●

After cleaning, always wipe the unit with a clean, lint-free cloth.

●

Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airow.

Cleaning the keyboard

Follow all safety precautions in General cleaning safety precautions on page 14 before cleaning the keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer

case on page 14.

When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 14 before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the

keys.

●

Visible debris underneath or between the keys may be removed by vacuuming or shaking.

Memory

Description

16-GB, PC4-17000

8-GB, PC4-17000

4-GB, PC4-17000

2-GB, PC4-17000

The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM) dual inline memory modules (DIMMs).

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 64 GB of memory congured in a high-performing dual channel mode.

DDR4-SDRAM DIMMs

For proper system operation, the DIMMs must be:

●

industry-standard 288-pin

●

unbuered non-ECC PC4-17000 DDR4-2133 MHz-compliant

●

1.2 volt DDR4-SDRAM DIMMs

The DIMMs must also:

●

support CAS latency 15 DDR4 2133 MHz (15-15-15 timing)

●

contain the mandatory JEDEC SPD information

In addition, the computer supports:

●

512-Mbit, 1-Gbit, and 2-Gbit 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.

Populating DIMM sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.

The system will automatically operate in single channel mode, dual channel mode, or ex mode, depending on how the DIMMs are installed.

NOTE: Single channel and unbalanced dual channel memory congurations will result in inferior graphics

performance.

24 Chapter 4 Removal and replacement procedures – small form factor (SFF) chassis

●

The system will operate in single channel mode if the DIMM sockets are populated in one channel only.

●

The system will operate in a higher-performing dual channel mode if the total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology and device width can vary between the channels. For example, if Channel A is populated with two 1 GB DIMMs and Channel B is populated with one 2 GB DIMM, the system will operate in dual channel mode.

●

The system will operate in ex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In ex 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. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. For example, if you are populating the sockets with one 2 GB DIMM, and three 1 GB DIMMs, Channel A should be populated with the 2 GB DIMM and one 1 GB DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this conguration, 4 GB will run as dual channel and 1 GB will run as single channel.

●

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

Installing DIMMs

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.

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 object.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

1. Prepare the computer for disassembly (Preparation for disassembly on page 18).

2. Remove the access panel (Access panel on page 19).

3. Rotate up the internal drive bay housing to access the memory module sockets on the system board.

4. 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.

Populate the black DIMM sockets before the white DIMM sockets.

For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to Populating DIMM sockets on page 24 for more information.

briey touching a grounded metal

5. Push the module down into the socket, ensuring that the module is fully inserted and properly seated.

Make sure the latches are in the closed position (3).

6. Repeat steps 4 and 5 to install any additional modules.

The computer should automatically recognize the additional memory the next time you turn on the computer.

Save/Restore MBR of the system hard drive

Smart Cover Cover Lock (Lock/Unlock)

Enabling this feature will save the Master Boot Record (MBR) of the system hard drive. If the MBR gets changed, the user will be prompted to restore the MBR. Default is disabled.

The MBR contains information needed to successfully boot from a disk and to access the data stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It also allows you to recover the "last known good" MBR, should changes to the MBR be detected when the system is restarted.

When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current bootable disk while in MS-DOS or Windows Safe Mode.

NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot

prevent changes that may occur while the operating system is running.
