Lenovo IdeaPad S145 Series Hardware Maintenance Manual

General safety

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.

•Please remove covers and other parts in a safe place, away from all personnel, while you are servicing the machine.

•Keep your toolcase 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 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.

Safety information

Electrical safety

Observe the following rules when working on electrical equipments.

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.

•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 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.

Lenovo IdeaPad S145 Series Hardware Maintenance Manual

•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

Safety inspection guide

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.

Lenovo IdeaPad S145 Series Hardware Maintenance Manual

Handling devices that are sensitive to electrostatic discharge

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.

•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 to guard against ESD damage is desirable but not necessary.

–Attach the ESD ground clip to any frame ground, ground braid, or greenwire ground.

–When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connectoroutside 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.

Lenovo IdeaPad S145 Series Hardware Maintenance Manual

Use the following strategy to prevent unnecessary expense for replacing and servicing FRU:

•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 FRU may be the cause of the error. Before replacing the adapter or device, remove the FRU 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.

Strategy for replacing a hard disk drive

Always try to run a low-level format before replacing a hard disk drive. This will cause all customer data on the hard disk to be lost. Make sure that the customer has a current backup of the data before performing this action.

Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect drive, data or programs can be overwritten.

Important notice for replacing a system board

Some components mounted on a system board are very sensitive. Improper handling can cause damage to those components, and may cause a system malfunction.

Attention: When handling a system board:

•Do not drop the system board or apply any excessive force to it.

•Avoid rough handling of any kind.

•Avoid bending the system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset.

Important service information

Important information about replacing RoHS compliant FRU

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 Lenovo’s requirements and schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS compliant FRU. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant FRU.

RoHS compliant FRU 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 FRU identified as compliant in the system HMM or direct substitutions for those FRU may be used.

Products marketed before June 2006		Products marketed after June 2006
Current or	Replacement FRU	Current or	Replacement FRU
original part		original part
Non-RoHS	Can be Non-RoHS

Non-RoHS	Can be RoHS	Must be RoHS	Must be RoHS

Non-RoHS	Can sub to RoHS

RoHS	Must be RoHS

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.

Important notes:

•Only certified trained personnel can service the computer.

•Before replacing any FRU, read the entire page on removing and replacing FRU.

•Carefully remove screws for reuse when replacing FRU.

•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.
