While your guarantee is immediately effective at the date of purchase, a few damage types are not covered by a standard guarantee, including: Accidental damage: unintentional physical damage to your product. For example, when you drop your camera and crack the screen. Liquid damage: exposing your product to any type of liquids when it is not labelled as waterproof. Improper handling: signs of wear and tear after being used for some duration of time. Improper handling of a product can speed up the aging.

A. Forcing a wrong cable in the wrong port may void the guarantee. B. If you don’t have your original purchase documents, you will be charged

for any repairs. C. Improper handling often results in liquid damage. D. Certain accidental damages are within dealer warranty.

MacBook Air: Display Assembly Replacement

The following connector has an

especially deep socket. Use care

when disconnecting it.

• Carefully peel the I/O board cable

from the top of the fan.

• While gently pulling the I/O board

cable upward near its connection to

the logic board, use the tip of a

spudger to pry upward on alternating

sides of the connector to help "walk"

it out of its socket.

• Remove the I/O board cable.

• Lubrication: This section will describe the lubricating locations on the machine, the types of lubricants to use, and the capacities.

• Inspection: Here you will find instructions for inspecting the equipment or machine. This may include electrical wiring inspections for damage or broken parts, corroded connectors, or blown fuses.

• Scheduled maintenance: Here you will find a calendar-type schedule for regular maintenance.

• Troubleshooting tips: Most maintenance manuals have a section covering troubleshooting tips, which are helpful in diagnosing mechanical problems in almost any machine.

• Specifications: This section, if your manual includes it, will give you facts about the machine's capabilities, performance, and capacities and may include a description of its size, weight, power and fuel requirements.

Datasheet

8

• A datasheet is a document that provides technical characteristics of a product, such as an electronic part, a computer component, or software program. The datasheet includes information that can help in making a buying decision by providing technical specifications about the product.

• A datasheet may offer a typical value, a typical range, and engineering tolerances.

• Note that a Material Safety Data Sheet (MSDS) is a different documentation - required by legal agencies - that provides workers with ways to work with the material in a safe manner.
