Chapter 1: Product Overview 1-11
Power Management
Power
management
is
implemented
on
the
7446
using
the
ACPI
1.1
Specification
1.1.
In
order
to
accomplish
this,
the
processor
board
is
equipped
with
ACPI
BIOS.
The
BIOS
supports
the
ACPI
1.1
specification.
This
permits
the
terminal
to
go
to
a
low
power
state
during
some
level
of
inactivity.
With
ACPI,
the
operating
system
has
some
control
over
the
power
management
by
going
into
suspend
,
standby
,
or
hibernate
(depending
on
the
Operating
System).
The
S0
,
S1
,
S4
,
and
S5
states
are
implemented.
For
the
detail
of
the
ACPI,
refer
to
ACPI
Specification
2.0b
.
Not
all
Entry
and
Exit
points
are
available
at
all
times.
Availability
is
based
on
ACPI
states.
Notes:
•
When
the
LAN
cable
is
connected
a
WakeOnLan
notification
is
sent
to
the
operating
systems,
causing
the
terminal
to
come
out
of
a
low
power
state
such
as
hibernation
under
Windows
2000/Windows
XP.
This
is
similar
to
the
WakeOnLan
feature.
•
Wake
on
Alarm
is
not
supported
from
the
ʺ
off
ʺ
state.
This
is
because
the
ACPI
power
management
in
the
BIOS
does
not
allow
the
Timer/Alarm
to
wake
the
system.
Wake
on
LAN
is
supported.
Similar
functionality
can
be
implemented
from
the
server
by
sending
a
LAN
wakeup
message.
•
Wake
on
Alarm
from
Window
NT
is
not
supported.
•
USB
devices
must
be
enabled
in
Windows
2000/Windows
XP
for
Wake
from
Standby
to
function.
This
is
set
in
at:
Start
Æ
Control
Panel
Æ
System
Æ
Hardware
Tab
Æ
Device
Manager
Æ
[USB
device]
Æ
Properties
.
There
is
a
check
box
to
enable
the
function
under
the
USB
tab.
