the
entry
for

Problem:
The
computer
does
not
respond.
Solution:
IRQs
for
the
PCI
are
all
set
as
11.
The
computer
does
not
respond
because
it
cannot
share
the
IRQ
with
other
devices.
Refer
to
the
ThinkPad
Configuration
Program.
Problem:
The
computer
can
not
play
a
CD,
or
the
sound
quality
is
not
good.
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
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.
