System-board
error
LEDs
The
following
illustration
shows
the
locations
of
the
LEDs
on
the
system
board.
You
might
need
to
refer
to
this
illustration
when
solving
problems
with
the
computer.
An
error
LED
on
the
system
board
is
lit
to
indicate
a
problem
with
a
specific
component.
The
error
LEDs
remain
lit
until
the
error
log
is
cleared,
this
prevents
spurious
errors
from
going
undetected.
After
a
problem
is
cleared,
the
LED
will
not
be
lit
the
next
time
the
computer
is
restarted;
if
the
problem
remains,
the
LED
will
be
lit
again.
