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.

IdeaPad S410p/S410p Touch/S510p/S510p Touch 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 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 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 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 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.

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certied(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 specic 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 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 correct

system function. Proper grounding of the electrical outlet can be veried by a

certied electrician.
