Solving computer problems 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 you are using a USB 1.x Chapter 2. Solving computer problems 33

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
you
are
using
a
USB
