IdeaPad Y460 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.
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 lou vers 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 bers 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 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:•
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 o n a machine that has exposed elec trical circuits, •
observe the following precautions:
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.
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
– 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 oor strips and machine frames.

IdeaPad Y460 Hardware Maintenance Manual
Always look carefully for possible hazards in your work area. Examples of •
these hazards are moist oors, 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 IdeaPad
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 rst 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 d etermine whethe r there are any potentia l unsafe conditio ns, 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 specied 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 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.

IdeaPad Y460 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 certied (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 specic 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 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 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 veried by a
certied electrician.

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 A utomati c Con figurat ion m ay alter the
settings. Note the current conguration settings (using the View Conguration
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 information about replacing RoHS compliant FRUs
RoHS, T he Restriction of Hazardous Sub sta nce s 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 t and function
are identied 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 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 i mplementation date, failed RoHS compliant parts must always be
replaced with RoHS compliant ones, so only the FRUs identied as compliant
in the system HMM or direct substitutions for those FRUs may be used.

Perform operational charging. If the battery status indicator or icon does not
light on, remove the battery pack and let it return to room temperature. Reinstall
the battery pack. If the charge indicator or icon is still off, replace the battery
pack.
If the charge indicator still does not light on, replace the system board. Then
reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95%
of the total power remains; under this condition the battery pack can charge to
100% of its capacity. This protects the battery pack from being overcharged or
from having a shortened life.
To check your battery, move your cursor to the Power Meter icon in the icon
tray of the Windows® taskbar and wait for a moment (but do not click it), and the
percentage of battery power remaining is displayed. To get detailed information
about the battery, double-click the Power Meter icon.
Note: If the battery pack becomes hot, it may not be able to be charged.
Remove it from the computer and leave it at room temperature for a while. After
it cools down, reinstall and recharge it.
To check the battery pack, follow the steps below:
1. Turn off the computer.
2. Remove the batt ery pack and meas ure the voltage between battery
terminals 1 (+) and 7 (-). See the following gure:
3. If the volta ge is les s than +11. 0 V D C, the batte ry pac k ha s been
discharged.
Note: Recharging will be continued for at least 3 hours, even though the
indicator does not light on.
If the voltage is still less than +11.0 V DC after recharging, replace the
battery.
4. If the voltage is more than +11.0 V DC, measure the resistance between
battery terminals 5 and 7. The resistance must be 4 to 30 KΩ.
If the resistance is not correct, replace the battery pack. If the resistance is
correct, replace the system board.

Restore of factory default
The IdeaPad Y460 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 is
shipped. If you need to restore the system to the point of your rst boot up, just
enter Lenovo OneKey Rescue System and run Restore to factory default. For
details of OneKey Rescue System, see
This will delete all the new data on the system partition (C drive), which
Note:
is not recoverable. Make sure to back up your critical data before you perform this
action.
Using recovery discs
When you replace a hard disk drive in your computer, you are unable to use
the pre-installed Lenovo OneKey Recovery and OneKey Rescue. However, you
can use the recovery discs that store your backed up data to restore your new
hard drive to a previous backup status.

When you use the recovery discs to boot your computer, the system will enter
the user interface for system recovery automatically. Please follow the prompt
to insert the backup discs to complete the whole recovery process.
The recovery process might take up to 2 hours.
Note:
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 screen
whenever the computer is turned on. The computer does not start until the
password is entered.
Exception: If only an SVP is installed, the password prompt does not appear
when the operating system is booted.
Power-on password
A power-on password (POP) protects the system from being powered on by
an unauthorized person. The password must be entered before an operating
system can be booted.
Supervisor password
A supervisor password (SVP) protects the system information stored in the
BIOS Setup Utility. The user must enter the SVP in order to get access to the
BIOS Setup Utility and change the system conguration.
Attention: If the SVP has been forgotten and cannot be made available to
the servicer, there is no service procedure to reset the password. The system
board must be replaced for a scheduled fee.
