Solution:
 
Be
 
sure
 
that
 
the
 
disk
 
meets
 
the
 
standards
 
for
 
your
 
country.
 
Usually,
 
a
 
disk
 
that
 
meets
 
the
 
local
 
standards
 
is
 
marked
 
with
 
a
 
CD
 
logo
 
on
 
the
 
label.
 
If
 
you
 
use
 
a
 
disc
 
that
 
does
 
not
 
meet
 
these
 
standards,
 
we
 
cannot
 
guarantee
 
that
 
it
 
will
 
play,
 
or
 
that,
 
if
 
it
 
does
 
play,
 
the
 
sound
 
quality
 
will
 
be
 
good.
  
 
Problem:
 
Playback
 
of
 
DVD
 
is
 
not
 
smooth
 
in
 
Windows
 
98
 
and
 
Windows
 
2000.
 
Solution:
 
If
 
you
 
select
 
the
 
Maximum
 
Battery
 
mode
 
for
 
the
 
Intel
 
SpeedStep
®
 
technology,
 
this
 
problem
 
may
 
occur.
 
This
 
mode
 
is
 
designed
 
to
 
achieve
 
maximum
 
battery
 
life
 
by
 
switching
 
the
 
processor
 
speed
 
between
 
the
 
regular
 
low
 
speed
 
and
 
half
 
of
 
that
 
speed,
 
depending
 
on
 
how
 
much
 
the
 
processor
 
is
 
used.
 
If
 
the
 
use
 
increases,
 
Intel
 
SpeedStep
 
switches
 
the
 
processor
 
speed
 
to
 
the
 
lower
 
speed.
 
Operation
 
in
 
this
 
mode
 
can
 
severely
 
degrade
 
the
 
performance
 
of
 
the
 
processor,
 
and
 
thus
 
cause
 
the
 
playback
 
of
 
a
 
DVD
 
to
 
be
 
jerky.
 
 
To
 
avoid
 
or
 
reduce
 
this
 
problem,
 
you
 
can
 
choose
 
any
 
of
 
three
 
other
 
modes
 
of
 
operation,
 
as
 
follows:
 
v
   
Maximum
 
Performance:
 
Keeps
 
the
 
processor
 
speed
 
high
 
at
 
all
 
times.
 
v
   
Automatic:
 
Switches
 
the
 
processor
 
speed
 
between
 
high
 
and
 
low,
 
depending
 
on
 
how
 
much
 
the
 
processor
 
is
 
used.
 
If
 
the
 
use
 
increases,
 
Intel
 
SpeedStep
 
switches
 
the
 
processor
 
speed
 
to
 
high.
 
v
   
Battery
 
Optimized
 
Performance:
 
Keeps
 
the
 
processor
 
speed
 
low
 
at
 
all
 
times.
 
To
 
choose
 
a
 
mode,
 
do
 
the
 
following:
 
1.
   
Start
 
the
 
ThinkPad
 
Configuration
 
Program.
 
2.
   
Click
 
Power
 
Management
.
 
3.
   
Click
 
the
 
Intel
 
SpeedStep
 
technology
 
tab.
 
4.
   
From
 
the
 
list,
 
select
 
the
 
mode
 
you
 
want.
 
5.
   
Click
 
OK
.
Problem:
 
You
 
cannot
 
connect
 
using
 
the
 
built-in
 
wireless
 
networking
 
card.
 
Solution:
 
If
 
the
 
computer
 
display
 
is
 
closed,
 
open
 
it
 
and
 
try
 
again.
 
Problem:
 
If
 
your
 
operating
 
system
 
is
 
Windows
 
2000
 
and
