Lenovo Notebook Computer User Guide
Note:
Since
there
are
several
sound
sources,
such
as
the
fan,
hard
disk
and
speakers
in
the
computer,
the
speakers
will
scream
when
the
volume
is
too
high.
This
is
caused
by
the
internal
speakers’
positive
feedbacks
and
can
be
eliminated
by
decreasing
the
volume.
When
you
are
performing
voice
recognition
tasks,
we
recommend
you
to
use
external
microphone,
because
the
inner
sound
of
the
computer
has
certain
effect
to
the
internal
microphones.
2.3 Setting display resolution
To
view
a
program
at
a
specific
resolution,
both
the
video
controller
and
display
must
support
the
program,
and
the
necessary
video
drivers
must
be
installed.
Before
you
change
any
of
the
original
display
settings,
record
the
original
settings
for
future
reference.
