Lenovo IdeaPad S400 Touch 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 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.

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

– Use only one hand when working with powered-on electrical equipment;

– When using testers, set the controls correctly and use the approved probe

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate

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 S400 Touch 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:
– Use caution: do not become a victim yourself.
–Switch off the power.
– Send the victim to get medical aid.

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 du e to 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 a ny obvious unsafe conditions, such as metal filin gs,
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 S400 Touch 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.

Notes:

The use of a grounding system to guard against ES D 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 verified by a
certified electrician.

Important service information

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

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
cop ying, sa ving, or formatt ing. I f you select a n incorr ect dr ive, data or p rogra ms
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, 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 number s with the same fit and fu nction are

identified with unique FRU part numbers.

Lenovo plans to tr ansit to RoHS compliance well b efore 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.

RoH S complian t FRUs have unique FRU part numbers. B efore or afte r the R oHS
implementation date, faile d RoHS compliant parts must always be repla ced with
RoHS compliant ones, so only the FRUs identified as compliant in the system
HMM or direct substitutions for those FRUs may be used.

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

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 n othing t o do with a hard ware d efect , such as co smic radia tion,
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.
