By following these important tips, you will get the most use and enjoyment out of your computer. Important tips: Be careful about where and how you work v Do not leave the base of your computer in contact with your lap or any part of your body for an extended period when the computer is functioning or when the battery is charging.

Extended contact with your body, even through clothing, could cause discomfort or, eventually, a skin burn. v Place liquids away from your computer to avoid spills, and keep your computer away from water (to avoid the danger of electrical shock). v Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. v Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm/5 in). v Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F). Be gentle with your computer v Avoid placing any objects (including paper) between the display and the keyboard or under the keyboard. v Do not drop, bump, scratch, twist, hit, vibrate, push or place heavy objects on your computer, display, or external devices. v Your computer display is designed to be opened and used at an angle slightly greater than 90 degrees. Do not open the display beyond 180 degrees, as this might damage the computer hinge. Carry your computer properly v Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect cords and cables. v Be sure your computer is in standby or hibernation mode, or turned off, before moving it.

Caring
for
your
ThinkPad
computer
Though
your
computer
is
designed
to
function
reliably
in
normal
work
environments,
you
need
to
use
common
sense
in
handling
it.
By
following
these
important
tips,
you
will
get
the
most
use
and
enjoyment
out
of
your
computer.
Important
tips:
Be
careful
about
where
and
how
you
work
v
Do
not
leave
the
base
of
your

with
your
lap
or
any
part
of
your
body
for
an
extended
period
when
the
computer
is
functioning
or
when
the
battery
is
charging.
Your
computer
dissipates
some
heat
during
normal
operation.
This
heat
is
a
function
of
the
level
of
system
activity
and
battery
charge
level.
Extended
contact
with
your
body,
even
through
clothing,
could
cause
discomfort

eventually,
a
skin
burn.
v
Place
liquids
away
from
your

avoid
spills,
and
keep
your

from
water
(to
avoid
the
danger
of
electrical
shock).

packing
materials
safely
out
of
the
reach
of
children
to
prevent
the
risk
of
suffocation
from
plastic
bags.
v
Keep
your

drop,
bump,
scratch,
twist,
hit,

push
or
place
heavy
objects
on
your

or
external
devices.
v
Your
computer
display
is
designed
to
be
opened
and
used
at
an
angle
slightly
greater
than
90
degrees.
Do
not
open
the
display
beyond
180
degrees,
as
this
might
damage
the
computer
hinge.
Carry
your
computer
properly
v
Before
moving
your
computer,
be
sure
to
remove
any
media,
turn

and
cables.
v
Be
sure
your
computer
is
in
standby
or
hibernation
mode,
or
turned
off,
before
moving
it.
This
will
prevent
damage
to
the
hard
disk
drive
and
data
loss.

When
picking
up
your
open
computer,
hold
it
by
the
bottom.
