vi P920 Hardware Maintenance Manual
Chapter 1. Read this first: Important safety information
This chapter contains the safety information that you must be familiar with.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product manufacturer. Do not use the ac
power cord for other devices.
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For
other countries, the suitable types shall be used accordingly.
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that
can cause the cord to fray, crack, or crimp. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power
adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short
circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can cause
gradual corrosion of power cord terminals and/or the connector terminals on a power adapter, which can
eventually result in overheating.
Ensure that all power cord connectors are securely and completely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such
as deformed plastic) at the ac input or anywhere on the power adapter.
Do not use any power cords where the electrical contacts on either end show signs of corrosion or
overheating or where the power cord appears to have been damaged in any way.
General safety
Follow these rules to ensure general safety:
• Observe good housekeeping in the area of the machines during and after maintenance.
• When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the
muscles in your back.
Attention: Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects that you
think are too heavy for you.
• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.
• Before you start the machine, ensure that other service representatives and the customer's personnel are
not in a hazardous position.
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the
machine.
© Copyright Lenovo 2017 1
• Keep your tool case away from walk areas so that other people will not trip over it.
• Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves
are fastened or rolled up above your elbows. If your hair is long, fasten it.
• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately
8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.
Remember: Metal objects are good electrical conductors.
• Wear safety glasses when you are: hammering, drilling, soldering, cutting wire, attaching springs, using
solvents, or working in any other conditions that might be hazardous to your eyes.
• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that
is worn or defective.
• Reinstall all covers correctly before returning the machine to the customer.
CAUTION:
Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury,
seek medical care immediately.
CAUTION:
Avoid contact with hot components inside the computer. During operation, some components
become hot enough to burn the skin. Before you open the computer cover, turn off the computer,
disconnect power, and wait approximately 10 minutes for the components to cool.
Electrical safety
CAUTION:
Electrical current from power, telephone, and communication cables can be hazardous. To avoid
personal injury or equipment damage, disconnect the attached power cords, telecommunication
systems, networks, and modems before you open the computer covers, unless instructed otherwise
in the installation and configuration procedures.
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft
material that does not insulate you when working with live electrical currents. Many customers have, near
their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges.
Do not use this type of mat to protect yourself from electrical shock.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical
accident occurs, you can then operate the switch or unplug the power cord quickly.
• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.
• Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing Field Replaceable Units (FRUs)
2P920 Hardware Maintenance Manual
• Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer
to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.
• If you need to work on a machine that has exposed electrical circuits, observe the following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another person must be there to switch off the power, if necessary.
– Use only one hand when working with powered-on electrical equipment; keep the other hand in your
pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By observing the above rule,
you may prevent a current from passing through your body.
– When using a tester, set the controls correctly and use the approved probe leads and accessories for
that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as
metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages; these instructions are in
the safety sections of maintenance information. Use extreme care when measuring high voltages.
• Regularly inspect and maintain your electrical hand tools for safe operational condition.
• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected from a circuit. First, check that it has been powered-off.
• Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors,
nongrounded power extension cables, power surges, and missing safety grounds.
• Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is
conductive; such touching can cause personal injury and machine damage.
• Do not service the following parts with the power on when they are removed from their normal operating
places in a machine:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
and similar units. (This practice ensures correct grounding of the units.)
• If an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these
products. Each machine, as it was designed and built, had required safety items installed to protect users
and service personnel from injury. This guide addresses only those items. However, good judgment should
be used to identify potential safety hazards due to attachment of features or options not covered by this
inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and
whether you can continue without first correcting the problem.
Consider these conditions and the safety hazards they present:
Chapter 1.Read this first: Important safety information 3
• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal
electrical shock).
• Explosive hazards, such as a damaged CRT face or bulging capacitor
• Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the
power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Power-off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground
continuity for 0.1 ohm or less between the external ground pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious alterations. Use good judgment as to the safety of any alterations.
6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or
other liquids, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered
with.
Handling electrostatic discharge-sensitive devices
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to
electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects.
Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the
person handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements noted here.
2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts:
• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people while handling the part.
• Wear a grounded wrist strap against your skin to eliminate static on your body.
• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when
you are wearing a wrist strap.
• Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially
useful when handling ESD-sensitive devices.
• Select a grounding system, such as those listed below, to provide protection that meets the specific
service requirement.
Note: The use of a grounding system is desirable but not required to protect against ESD damage.
4P920 Hardware Maintenance Manual
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
– Use an ESD common ground or reference point when working on a double-insulated or battery-
operated system. You can use coax or connector-outside shells on these systems.
– Use the round ground-prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct system function. Proper
grounding of the electrical outlet can be verified by a certified electrician.

Arranging your workspace
Arrange your workspace to suit your needs and the kind of work you do. This section provides information
about the factors that affect the way you arrange your workspace.
Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights, windows, and other light
sources. Reflected light from shiny surfaces can cause annoying reflections on your screen. When possible,
place the monitor at right angles to windows and other light sources. If necessary, reduce overhead lighting
by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or
blinds to block the sunlight. You can adjust the brightness and contrast controls on the monitor as the room
lighting changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen
might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after
you have exhausted other methods of reducing glare.
Air circulation
Your computer produces heat. The computer has a fan that pulls in fresh air and forces out hot air through
the air vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage.
Position the computer so that nothing blocks the air vents; usually, 51 mm (2 inches) of air space is sufficient.
Ensure that the vented air is not blowing on people.
Electrical outlet locations and cable lengths
The following factors might determine the final placement of your computer:
• Locations of electrical outlets
• Length of power cords or power adapters
• Length of the cables that are connected to other devices
For more information about power cords or power adapters, see “Power cords and power adapters” on page
1.
Comfort
Although no single working position is ideal for everyone, here are a few guidelines to help you find a position
that suits you best. The following figure sets an example for your reference.
© Copyright Lenovo 2017 53
• Screen position: Keep the screen at a comfortable viewing distance, usually 51–61 cm (20–24 inches).
Then, adjust the screen so that the top of the screen is at or slightly below eye level and you can view it
without twisting your body.
• Chair position: Use a chair that gives you good back support and seat height adjustment. Use chair
adjustments to best suit your desired posture.
• Head position: Keep your head and neck in a comfortable and neutral (vertical or upright) position.
• Arm and hand positions: Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)
position. Type with a soft touch without pounding the keys.
• Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
Make minor modifications in your working posture to deter the onset of discomfort caused by long periods of
working in the same position. Frequent short breaks from your work also help to prevent minor discomfort
associated with your working posture.

RAID is a technology that provides increased storage functions and reliability through redundancy.
When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID
array. This array distributes data across multiple storage drives, but the array appears to the host computer
as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited
I/O performance, because several drives can be accessed simultaneously.
RAID drive groups configured according to certain RAID levels also improve data storage reliability and fault
tolerance compared with single-drive storage systems. Data loss resulting from a drive failure can be
prevented by reconstructing missing data from the remaining drives.
Note: For RAID 0, the missing data resulting from a drive failure cannot be reconstructed.
Configuring RAID with Intel RSTe
If your computer comes with the Intel RSTe configuration utility, you can follow the sections below to
configure RAID with Intel RSTe.
Storage drive requirements for RAID levels

Chapter 8. Service checkout and symptom-to-FRU index
This chapter provides information about general service checkout and symptom-to-FRU index.
Service checkout
Attention: The drives in the computer you are servicing might have been rearranged or the drive startup
sequence changed. Be extremely careful during write operations such as copying, saving, or formatting.
Data or programs can be overwritten if you select an incorrect drive.
General error messages appear if a problem or conflict is found by a program, the operating system, or both.
For an explanation of these messages, refer to the information supplied with that software package.
Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS
might cause false errors and unnecessary replacement of the system board. For more information about how
to determine and obtain the latest level BIOS, see “BIOS level” on page 72.
Use the following procedure to help determine the cause of the problem:
1. Turn off the computer and all external devices.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Turn on all external devices.
5. Turn on the computer.
• Look for displayed error codes.
• Listen for beep codes.
• Look for readable instructions or a main menu on the display.
If you did not receive the correct response, proceed to step 6 on page 95.
If you do receive the correct response, proceed to step 7 on page 95.
6. Look at the following conditions and follow the instructions:
• If you hear beep codes during POST, go to “Beep symptoms” on page 97.
• If the computer displays a POST error, go to “POST error codes” on page 98.
• If the computer hangs and no error is displayed, continue at step 7 on page 95.
7. Run the Diagnostic programs. See “Diagnosing problems” on page 89.
• If you receive an error, replace the part that the diagnostic program calls out.
• If the test stops and you cannot continue, replace the last device tested.
Problem determination tips
Due to the variety of hardware and software combinations that can be encountered, use the following
information to assist you in problem determination. If possible, have this information available when
requesting assistance from Service Support and Engineering functions.
• Machine type and model
• Processor or hard disk drive upgrades
• Failure symptom
– Do diagnostics indicate a failure?
© Copyright Lenovo 2017 95
– What, when, where, single, or multiple systems?
– Is the failure repeatable?
– Has this configuration ever worked?
– If it has been working, what changes were made prior to its failing?
– Is this the original reported failure?
• Diagnostics version
– Type and version level
• Hardware configuration
– Print (print screen) configuration currently in use
– BIOS level
• Operating system software
– Type and version level
Notes: To eliminate confusion, identical systems are considered identical only if they:
1. Are the exact machine type and models
2. Have the same BIOS level
3. Have the same adapters/attachments in the same locations
4. Have the same address jumpers/terminators/cabling
5. Have the same software versions and levels
6. Have the same Diagnostic Diskettes (version)
7. Have the same configuration options set in the system
8. Have the same setup for the operating system control files
Comparing the configuration and software set-up between “working and non-working” systems will often
lead to problem resolution.
Symptom-to-FRU index
The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first.
Always begin with “Service checkout” on page 95. This index can also be used to help you decide which
FRUs to have available when servicing a computer. If you are unable to correct the problem using this index,
go to “Undetermined problems” on page 101.
Notes:
• The Symptom-to-FRU index is not specific to any machine type and are applicable to all ThinkStation computers.
• If you have both an error message and an incorrect audio response, diagnose the error message first.
• If you cannot run the diagnostic tests or you get a diagnostic error code when running a test, but did receive a
POST error message, diagnose the POST error message first.
• If you did not receive any error message, look for a description of your error symptoms in the first part of this index.

Chapter 9. Hardware removal and installation
This chapter provides instructions on how to remove and install hardware for your computer.
Handling static-sensitive devices
Do not open the static-protective package containing the new part until the defective part has been removed
and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage
computer components and options.
When you handle options and other computer components, take these precautions to avoid static-electricity
damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle options and other computer components carefully. Handle PCI/PCIe cards, memory
modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the options and other computer components.
• Touch the static-protective package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the
package and your body before you install or replace a new part.
• When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package on
a smooth, level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.
