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 anyobject 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 conditionsthat 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 orstickers.

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 handlescovered with a soft material that does not insulate you when working with liveelectrical currents.

Many customers have rubber floor mats near their machines that contain smallconductive bers to decrease electrostatic discharges. Do not use such kind of matto protect yourself from electrical shock.

Find the room emergency power-off (EPO) switch, 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 unitsBefore 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 suppliespower 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 completecircuit. By observing the above rule, you may prevent a current frompassing through your body.

– When using testers, set the controls correctly and use the approvedprobe leads and accessories for that tester. – Stand on suitable rubber mats (obtained locally, if necessary) to insulate

you from grounds such as metal oor 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 maintenanceinformation. 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.

Always look carefully for possible hazards in your work area. Examples of• these hazards are moist oors, nongrounded power extension cables, powersurges, 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 personalinjury 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 generatorsand 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 potentialunsafe conditions. As each machine was designed and built, required safetyitems were installed to protect users and service personnel from injury. Thisguide addresses only those items. You should use good judgment to identifypotential safety hazards according to the attachment of non-Lenovo IdeaPadfeatures or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious theapparent hazard could be and whether you can continue without rst correctingthe 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 thefollowing checklist at the beginning of every service task. Begin the checks withthe 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 measurethird-wire ground continuity for 0.1 ohm or less between the externalground pin and the frame ground.

b. The power cord should be the type speci ed 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 IdeaPad alterations. Use good judgment

as to the safety of any non-Lenovo IdeaPad 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 smokedamage.

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.

Handling devices that are sensitive to electrostatic discharge

Any computer part containing transistors or integrated circuits (ICs) should beconsidered sensitive to electrostatic discharge (ESD). ESD damage can occurwhen there is a difference in charge between objects. Protect against ESDdamage 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 certi ed (ISO9000) 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 speci c service requirement.

Note:The use of a grounding system to guard against ESD damage is desirable but notnecessary.

– 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 anESD 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.

Grounding requirements

Electrical grounding of the computer is required for operator safety and correctsystem function. Proper grounding of the electrical outlet can be veri ed by acerti ed electrician.

Important service information

Use the following strategy to prevent unnecessary expense for replacing andservicing 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 notsolve 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 onlythe FRU that changed the symptoms.

Attention: The setup configuration on the computer you are servicing mayhave been customized. Running Automatic Configuration may alter thesettings. Note the current con guration settings (using the View Con guration

option); then, when service has been completed, verify that those settingsremain in effect.

Strategy for replacing a hard disk drive Always try to run a low-level format before replacing a hard disk drive. Thiswill cause all customer data on the hard disk to be lost. Make sure that thecustomer has a current backup of the data before performing this action.Attention: The drive startup sequence in the computer you are servicing mayhave been changed. Be extremely careful during write operations such ascopying, saving, or formatting. If you select an incorrect drive, data or programscan be overwritten.

Important notice for replacing a system boardSome components mounted on a system board are very sensitive. Improperhandling can cause damage to those components, and may cause a systemmalfunction.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 information about replacing RoHS compliant FRUs

RoHS, The Restriction of Hazardous Substances in Electrical andElectronic Equipment Directive (2002/95/EC) is a European Union legalrequirement affecting the global electronics industry. RoHS requirementsmust be implemented on Lenovo products placed on the market afterJune 2006. Products on the market before June 2006 are not required tohave RoHS compliant parts. If the original FRU parts are non-compliant,replacement parts can also be non-compliant. In all cases if the originalFRU parts are RoHS compliant, the replacement part must also be RoHScompliant.

Note: RoHS and non-RoHS FRU part numbers with the same t and functionare identi ed with unique FRU part numbers.

Lenovo plans to transit to RoHS compliance well before the implementationdate and expects its suppliers to be ready to support Lenovo’s requirementsand schedule in the EU. Products sold in 2005 and 2006 will contain someRoHS compliant FRUs. The following statement pertains to these products andany product Lenovo produces containing RoHS compliant FRUs.

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

Products marketed before June 2006 Products marketed after June 2006

Restoring the factory contents by using OneKey Recovery

Restore of factory defaultThe IdeaPad U460 computers come with pre-installed OneKey Rescue System.In order to save application les and the initial backed up les of the system,the hard disk in a Lenovo computer includes a hidden partition when it isshipped. If you need to restore the system to the point of your rst boot up, justenter Lenovo OneKey Rescue System and run Restore to factory default . Fordetails of OneKey Rescue System, see the User Guide for OneKey Rescue System .

Note: This will delete all the new data on the system partition (C drive), whichis not recoverable. Make sure to back up your critical data before you perform thisaction.

Using recovery discsWhen you replace a hard disk drive in your computer, you are unable to usethe pre-installed Lenovo OneKey Recovery and OneKey Rescue. However, youcan use the recovery disc s that store your backed up data to restore your newhard drive to a previous backup status.

Note: You can create recovery disc s by burning the backup image to a CD/DVDas recovery discs. For details of Create recovery discs , see the User Guide forOneKey Rescue System .

When you use the recovery discs to boot your computer, the system will enterthe user interface for system recovery automatically. Please follow the promptto insert the backup disc s to complete the whole recovery process.

Note: The recovery process might take up to 2 hours.

Passwords

As many as two passwords may be needed for any Lenovo IdeaPad computer:the power-on password (POP) and the supervisor password (SVP).If any of these passwords has been set, a prompt for it appears on the screenwhenever the computer is turned on. The computer does not start until thepassword is entered.

Exception : If only an SVP is installed, the password prompt does not appearwhen the operating system is booted.

Power-on password A power-on password (POP) protects the system from being powered on byan unauthorized person. The password must be entered before an operatingsystem can be booted.

Supervisor password A supervisor password (SVP) protects the system information stored in theBIOS Setup Utility. The user must enter the SVP in order to get access to theBIOS Setup Utility and change the system con guration.

Attention: If the SVP has been forgotten and cannot be made available tothe servicer, there is no service procedure to reset the password. The systemboard must be replaced for a scheduled fee.
