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:
You
may
receive
an
“Unsafe

of
Device”
message
that
mentions
the
USB
1.x
device
when
you
resume
from
suspend
or
hibernation
in
Windows
2000.
Solution:
You
can
safely
close
this
message
window.
It
is
displayed
because
of
a
USB
2.0
driver
problem
in
Windows

Problem:
The
computer
cannot
play
a
CD,
or
the
sound
quality
of
a
CD
is
not
good.
Solution:
Be
sure
that
the
disk
meets
the
standard
for
your
country.
Usually,
a
disk
that
meets
the
local
standards
is
marked
with
a
CD
logo
(as
shown
below)
on
the
label.
If
you
use
a
disk
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:
The
system
shows
slow
performance.
Solution:
This
problem
may
occur
when
the
ac
adapter
is
not
attached.
To
prolong
battery
life
with
the
higher
frequency
of
Intel’s
Pentium
4/Celeron
processors,
the
ThinkPad
G40
implements
the
Dynamic
CPU
Throttling
feature,
which
reduces
CPU
frequency
dynamically:
1)
when
the
system
operates
in
battery
mode;
2)
when
the
system
increases
power
consumption;
3)
when
system
temperature
increases.
To
avoid
or
reduce
this
problem,
do
one
or
all
of
the
following:
1.
Attach
the
ac
adapter.
2.
Close
applications
not
being
used.
3.
Try
to
lower
system
temperature
by
increasing
the
fan
speed
with
the
Battery
MaxiMiser
Wizard
with
Fan
Control.
Problem:
Playback
of
DVD
is
not
smooth.
