Lenovo 3000 J Series Manual

							v   
 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. 
v 
 
 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. 
v 
 
 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.) 
v   
 If an electrical accident occurs: 
– 
 
 Use caution; do not become a victim yourself. 
– 
 
 Switch off power. 
– 
 
 Send another person to get medical aid.
Safety inspection guide 
The intent of this inspection guide is to assist you in identifying potentially unsafe 
conditions on these products. Each machine, as it was designed and built, had 
required safety items installed to protect users and service personnel from injury. 
This guide addresses only those items. However, good judgment should be used to 
identify potential safety hazards due to attachment of 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: 
v 
 
 Electrical hazards, especially primary power (primary voltage on the frame can 
cause serious or fatal electrical shock). 
v 
 
 Explosive hazards, such as a damaged CRT face or bulging capacitor 
v 
 
 Mechanical hazards, such as loose or missing hardware 
The guide consists of a series of steps presented in a checklist. 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. 
 
 Power-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 frame ground. 
b. 
 
 The power cord should be the appropriate type as specified in the parts 
listings. 
c. 
 
 Insulation must not be frayed or worn.
4.
   
 Remove the cover. 
 
Chapter 2. Safety information 5 
						

							5.   
 Check for any obvious alterations. Use good judgment as to the safety of any 
alterations. 
6. 
 
 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. 
7. 
 
 Check for worn, frayed, or pinched cables. 
8. 
 
 Check that the power-supply cover fasteners (screws or rivets) have not been 
removed or tampered with.
Handling electrostatic discharge-sensitive devices 
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: 
v 
 
 Keep the parts in protective packages until they are inserted into the product. 
v 
 
 Avoid contact with other people. 
v 
 
 Wear a grounded wrist strap against your skin to eliminate static on your body. 
v 
 
 Prevent the part from touching your clothing. Most clothing is insulative and 
retains a charge even when you are wearing a wrist strap. 
v 
 
 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. 
v 
 
 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 is desirable but not required to protect 
against ESD damage. 
– 
 
 Attach the ESD ground clip to any frame ground, ground braid, or green-wire 
ground. 
– 
 
 Use an ESD common ground or reference point when working on a 
double-insulated or battery-operated system. Yo u 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 verified by a 
certified electrician.
