Standby: all devices that consume large amounts of
energy are turned off, such as the monitor, hard disks
and other devices.
z Hibernation: also stores the contents of main memory

is even lower than on standby.
Does the Computer Support ACPI?
Use the following checklist to determine whether your com-
puter supports ACPI:
z You work with Windows XP, Me or 2000.
z Windows XP: ACPI-capable components are listed
under “System devices” on the “Device Manager”
settings page (“Start / Control Panel / Performance and
Maintenance / System / Hardware”).
z Windows Me: ACPI-capable components are listed
under “System devices” on the “Device Manager”
settings page (“Start / Settings / Control Panel /
System”).
z Windows 2000: ACPI-capable components are listed
under “System devices”, accessed by clicking the
“Device Manager” button on the “Hardware” settings
page (“Start / Settings / Control Panel / System”).
z The command “Stand by” appears along with
“Hibernate” in the “Shut Down” window, opened
through the “Start” menu.
If your computer is to remain ready to receive incoming
calls, hibernation must be available on the computer
but deactivated.
z All of the devices installed on your computer support
ACPI.
One single component installed on the computer that
does not support APCI can make it impossible to use
standby or hibernation.
