66 Chapter 5 Last, but Not Least
For your safety and that of your equipment, follow these rules for handling and
cleaning your MacBook Pro and for working more comfortably. Keep these instructions
handy for reference by you and others.
Important Safety Information
Built-in battery Do not remove the battery from your MacBook Pro. The battery
should be replaced only by an Apple Authorized Service Provider. Discontinue use of
your MacBook Pro if it is dropped or appears crushed, bent, deformed, or damaged. Do
not expose the computer to temperatures above 212° F or 100° C.
Proper handling Set up your MacBook Pro on a stable work surface that allows for
adequate air circulation under and around the computer. Do not operate your
MacBook Pro on a pillow or other soft material, because the material can block the
airflow vents. Never place anything over the keyboard when operating your
MacBook Pro. Never push objects into the ventilation openings.
The bottom of your MacBook Pro may become very warm during normal use. If your
MacBook Pro is on your lap and gets uncomfortably warm, move it to a stable work
surface.
Water and wet locations Keep your MacBook Pro away from sources of liquid, such as
drinks, washbasins, bathtubs, shower stalls, and so on. Protect your MacBook Pro from
dampness or wet weather, such as rain, snow, and fog.
WARNING: Failure to follow these safety instructions could result in fire, electric
shock, or other injury or damage.
