by
looking at the
on/off
indicator. If
the indicator
is
glowing,
the computer
is on. Also, try turning
the

To
clear the

computer
via software,
or

the documentation
that came
with
the
conflicting
device
and
"Resolving
a
hardware
conflict" in
your
electronic
user's
guide.

mode
light is

press
Fn

0 to turn off the
cursor control mode
light,
or Fn + Fl

turn off the numlock

If
the
problem
occurs
when both
the keypad
overlays are off, make
sure
the software
you
are using is
not remapping
the keyboard.
Refer
to the
software
documentation
and check that
the
program
does
not
assign
different
meanings
to any
of the keys.
