When your computer is turned on or the

battery is charging, the base, the palm rest,

and some other parts may become hot.

Avoid keeping your hands, your lap, or any

other part of your body in contact with a

hot section of the computer for any

extended length of time. When you use the

keyboard, avoid keeping your palms on the

palm rest for a prolonged period of time.

Your computer generates some heat dur-

ing normal operation. The amount of heat

depends on the amount of system activity

and the battery charge level. Extended

contact with your body, even through

clothing, could cause discomfort or even a

skin burn. Periodically take breaks from

using the keyboard by lifting your hands

from the palm rest; and be careful not to

use the keyboard for any extended length

of time.

iv Lenovo IdeaPad Safety and Warranty Guide

When the AC adapter is connected to an

electrical outlet and your computer, it

generates heat. Do not place the adapter

in contact with any part of your body

while using it. Never use the AC adapter

to warm your body. Extended contact

with your body, even through clothing,

may cause a skin burn.

Route the cables of an AC adapter, a

mouse, a keyboard, a printer, or any other

electronic device, or communication lines,

so that they cannot be walked on, tripped

over, pinched by your computer or other

objects, or in any way subjected to treat-

ment that could disturb the operation of

your computer. Applying strong force to

the cables may damage or break them.

Before moving your computer, do one of

the following: turn it off or press Fn+F1 to

put it in sleep mode, or hibernation mode.

Before moving the computer, make sure

that the power on indicator is off. This

will help to prevent damage to the hard

disk drive, and possible loss of data.

Do not drop, bump, scratch, twist, hit,

vibrate, push, or place heavy objects on

your computer, display, or external

devices.

Use a quality carrying case that provides

adequate cushion and protection. Do not

pack your computer in a tightly packed

suitcase or bag.

Place liquids away from your computer to

avoid spills, and keep your computer

away from water to avoid the danger of

electrical shock.

Note: This information includes references to power adapters

and batteries. In addition to notebook computers, some

products (such as speakers and monitors) ship with

external power adapters. If you have such a product, this

information applies to your product. In addition,

computer products contain a coin-sized internal battery

that provides power to the system clock even when the

computer is unplugged, so the battery safety information

applies to all computer products.

Conditions That Require Immediate Action

Products can become damaged due to misuse or neglect. Some

product damage is serious enough that the product should not

be used again until it has been inspected and, if necessary,

repaired by an authorized servicer.

As with any electronic device, pay close attention to the

product when it is turned on. On very rare occasions, you

might notice an odor or see a puff of smoke or sparks vent from

your product. Or you might hear sounds like popping,

cracking, or hissing. These conditions might merely mean that

an internal electronic component has failed in a safe and

controlled manner. Or, they might indicate a potential safety

issue. However, do not take risks or attempt to diagnose the

situation yourself. Contact the Customer Support Center for
