Lenovo IdeaTab A1000L Hardware Maintenance Manual

Any
computer
part
containing
transistors
or
integrated
circuits
(ICs)
should
be
considered
sensitive
to
electrostatic
discharge
(ESD).
ESD
damage
can
occur
when
there
is
a
difference
in
charge
between
objects.
Protect
against
ESD
damage
by
equalizing
the
charge
so
that
the
machine,
the
part,
the
work
mat,
and
the
person
handling
the
part
are
all
at
the
same
charge.
When
handling
ESD
‐
sensitive
parts:
•
Keep
the
parts
in
protective
packages
until
they
are
inserted
into
the
product.
•
Avoid
contact
with
other
people.
•
Wear
a
grounded
wrist
strap
against
your
skin
to
eliminate
static
on
your
body.
•
Prevent
the
part
from
touching
your
clothing.
Most
clothing
is
insulative
and
retains
a
charge
even
when
you
are
wearing
a
wrist
strap.
•
Use
the
black
side
of
a
grounded
work
mat
to
provide
a
static
‐
free
work
surface.
The
mat
is
especially
useful
when
handling
ESD
‐
sensitive
devices.
•
Select
a
grounding
system,
such
as
those
listed
below,
to
provide
protection
that
meets
the
specific
service
requirement.
– Attach the ESD ground clip to any frame ground, ground braid, or green-
wire ground.
– When working on a double-insulated or battery-operated system, use an
ESD common ground or reference point. You can use coax or connector-
outside shells on these systems.
– Use the round ground prong of the ac plug on ac-operated computers.
Electrical
grounding
of
the
computer
is
required
for
operator
safety
and
correct
system
function.
Proper
grounding
of
the
electrical
outlet
can
be
verified
by
a
certified
electrician.
Handling devices that are sensitive to electrostatic discharge
Notes:
1. Use product-specific ESD procedures when they exceed the
requirements noted here.
2.
Make
sure
that
the
ESD
protective
devices
you
use
have
been
certified
(ISO
9000)
as
fully
effective.
Notes:
The
use
of
a
grounding
system
to
guard
against
ESD
damage
is
desirable
but
not
necessary.
