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

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.

pack your computer in a tightly packed
suitcase or bag.

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
