Lenovo IdeaTab S2110A Hardware Maintenance Manual

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.

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.

– 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.

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.

Handling devices that are sensitive to electrostatic discharge

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.

Notes:

The use of a grounding system to guard against ESD damage is desirable but

not necessary.
