Lenovo A7600 Hardware Maintenance Manual

Follow these rules below to ensure general safety: Observe a good housekeeping in the area where the machines are put during

and after the maintenance. When lifting any heavy object:

1. Make sure that 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 it. 4. Lift it by standing or pushing up with your leg muscles; this action could

avoid the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you.

Do not perform any action that causes hazards to the customer, or that makes the machine unsafe.

Before you start the machine, make sure that other service representatives and the customer are not in a hazardous position.

Place removed covers and other parts in a safe place, keeping them away from all personnel, while you are servicing the machine.

Keep your toolcase away from walk areas so that other people will not trip it over.

Do not wear loose clothing that can be trapped in the moving parts of the machine. Make sure 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 the nonconductive clip, about 8 centimeters (3 inches) from the end.

Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Attention: 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 may 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. Fan louvers on the machine help to prevent the overheating of internal

components. Do not obstruct fan louvers or cover them with labels or stickers.

General safety

Safety information

Observe the following rules when working on electrical equipments.

Find the room emergency power-off (EPO) switch for disconnecting the 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 the equipment that has hazardous voltages.

Disconnect all power before: Performing a mechanical inspection Working near power supplies Removing or installing main units

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. Attention: 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. Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body.

When using testers, 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; instructions for these precautions are in the safety sections of maintenance information. Be extremely careful when you measure the 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 it

to make sure that it has been powered off.

Electrical safety

Important: Use only approved tools and test equipments. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have rubber floor mats near their machines that contain small conductive fibers to decrease electrostatic discharges. Do not use such kind of mat to protect yourself from electrical shock.

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: Caution: do not become a victim yourself. Switch off the power. Send the victim to get medical aid.

Safety information

The purpose of this inspection guide is to assist you in identifying potential unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards according to the attachment of non-Lenovo 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: 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 a bulging capacitor Mechanical hazards, such as loose or missing hardware

To determine whether there are any potential unsafe conditions, use the following checklist at the beginning of every service task. 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. Turn 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 the frame ground.

b. The power cord should be the type specified in the parts list. c. Insulation must not be frayed or worn.

4. Check for cracked or bulging batteries. 5. Remove the cover. 6. Check for any obvious non-Lenovo alterations. Use good judgment as to the

safety of any non-Lenovo alterations. 7. 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. 8. Check for worn, frayed, or pinched cables. 9. Check that the power-supply cover fasteners (screws or rivets) have not been

removed or tampered with.

Safety inspection guide

Lenovo A7600 Hardware Maintenance Manual

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.

When handling ESD-sensitive parts: Keep the parts in protective packages until they are inserted into the product. Avoid contact with other people. 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.

Attach the ESD ground clip to any frame ground, ground braid, or green- wire ground.

When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector- outside shells on these systems.

Use the round ground prong of the ac plug on ac-operated computers.

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.

Handling devices that are sensitive to electrostatic discharge

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.

Notes:

The use of a grounding system to guard against ESD damage is desirable but not necessary.

Important notice for replacing a system board on page 17 Important information about replacing RoHS compliant FRUs on page 18

Before replacing parts:

Make sure that all software fixes, drivers, and BIOS downloads are installed before replacing any FRUs listed in this manual. After a system board is replaced, ensure that the latest BIOS is loaded to the system board before completing the service action. To download software fixes, drivers, and BIOS, follow the steps below: 1. Go to http://consumersupport.lenovo.com/. 2. Enter a serial number or select a product or use Lenovo smart downloading. 3. Select the BIOS/Driver/Applications and download. 4. Follow the directions on the screen and install the necessary software.

Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: If you are instructed to replace an FRU, but the replacement does not solve

the problem, reinstall the original FRU before you continue. Some computers have both a processor board and a system board. If you are

instructed to replace either of them, and replacing one of them does not solve the problem, reinstall that board, and then replace the other one.

If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs one by one to see if the symptoms change. Replace only the FRU that changed the symptoms.

Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.

Important service information

Important: BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the customer support site: http://consumersupport.lenovo.com/.

RoHS, The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive (2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS requirements must be implemented on Lenovo products placed on the market after June 2006. Products on the market before June 2006 are not required to have RoHS compliant parts. If the original FRU parts are non-compliant, replacement parts can also be non-compliant. In all cases if the original FRU parts are RoHS compliant, the replacement part must also be RoHS compliant.

Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified with unique FRU part numbers.

Lenovo plans to transit to RoHS compliance well before the implementation date and expects its suppliers to be ready to support Lenovos requirements and schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant FRUs.

RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS implementation date, failed RoHS compliant parts must always be replaced with RoHS compliant ones, so only the FRUs identified as compliant in the system HMM or direct substitutions for those FRUs may be used.

Note: A direct substitution is a part with a different FRU part number that is automatically shipped by the distribution center at the time of the order.

Before you go to the checkout, make sure to read the following important notes:

General checkout

Important notes: Only certified trained personnel can service the computer. Before replacing any FRU, read the entire page on removing and

replacing FRUs. When you replace FRUs, use new nylon-coated screws. Be extremely careful during such write operations as copying,

saving, or formatting. Drives in the computer that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten.

Replace an FRU only with another FRU of the correct model. When you replace an FRU, make sure that the machine model and the FRU part number are correct by referring to the FRU parts list.

An FRU should not be replaced just because of a single, unreproducible failure. Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. Consider replacing an FRU only when a problem recurs. If you suspect that an FRU is defective, clear the error logs and run the test again. If the error does not recur, do not replace the FRU.

Be careful not to replace a nondefective FRU.

This section presents notices related to removing and replacing parts. Read this section carefully before replacing any FRU.

Screw notices Loose screws can cause a reliability problem. In Lenovo computers, this problem is addressed with special nylon-coated screws that have the following characteristics: They maintain tight connections. They do not easily come loose, even with shock or vibration. They are harder to tighten. Each one should be used only once.

Do the following when you service this machine: Keep the screw kit in your tool bag. Always use new screws. Use a torque screwdriver if you have one.

Tighten screws as follows: Plastic to plastic

Turn an additional 90 after the screw head touches the surface of the plastic part:

Logic card to plastic Turn an additional 180 after the screw head touches the surface of the logic card:

Torque driver If you have a torque screwdriver, refer to the Torque column for each step.

Make sure that you use the correct screws. If you have a torque screwdriver, tighten all screws firmly to the torque shown in the table. Never use a screw that you removed. Use a new one. Make sure that all screws are tightened firmly.

Ensure torque screwdrivers are calibrated correctly following country specifications.

This section presents exploded figures with the instructions to indicate how to remove and replace the FRU. Make sure to observe the following general rules: 1. Do not attempt to service any computer unless you have been trained and

certified. An untrained person runs the risk of damaging parts. 2. Before replacing any FRU, review FRU replacement notices on page 26. 3. Begin by removing any FRUs that have to be removed before the failing FRU.

Any of such FRUs are listed at the top of the section that describes the detailed removing and replacing procedure for the failing FRU. Remove them in the order in which they are listed.

4. Follow the correct sequence in the steps to remove the FRU, while referring to figures provided in the procedure.

5. When turning a screw to replace an FRU, turn it in the direction as given by the arrow in the figure.

6. When removing the FRU, move it in the direction as given by the arrow in the figure.

7. To put the new FRU in place, reverse the removal procedures and follow any of the notes that pertain to replacement. For information about connecting and arranging internal cables, see Locations on page 73.

8. When replacing an FRU, use the correct screw as specified in the procedures.

Attention: After replacing an FRU, do not turn on the computer until you have made sure that all screws, springs, and other small parts are in place and none are loose inside the computer. Verify this by shaking the computer gently and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.

Attention: The system board is sensitive to, and can be damaged by, electrostatic discharge. Before touching it, establish personal grounding by touching a ground point with one hand or using an electrostatic discharge (ESD) strap (P/N 6405959) to remove potential shock reasons.
