Passwords
As
many
as
three
passwords
may
be
needed
for
any
ThinkPad
computer:
the
power-on
password
(POP),
the
hard-disk
password
(HDP),
and
the
supervisor
password
(SVP).
If
any
of
these
passwords
has
been
set,
a
prompt
for
it
appears
on
the
screen
whenever
the
computer
is
turned
on.
The
computer
does
not
start
until
the
password
is
entered.
Exception:
If
only
an
SVP
is
installed,
the
password
prompt
does
not
appear
when
the
operating
system
is
booted.
Power-on
password

power-on
password
(POP)
protects
the
system
from
being
powered
on
by
an
unauthorized
person.
The
password
must
be
entered
before
an
operating
system
can
be
booted.
For
how
to
remove
the
POP,
