The ability to respond to external interrupts is fully maintained while
in Stand By mode allowing the system to service requests such as incoming
data or network messages while unattended. The user may
also make any keyboard or mouse activity to take the system out of the
energy saving Stand By mode. When this occurs, the monitor and IDE
drives are turned back on immediately.
Advanced Power Management (APM) is achieved by the following:
• DOS requires a driver (FS‐APM.dos)
• NT requires a driver (NCRSYSM.SYS)
• Windows 2000 must enable the operating system APM setting. The
OS APM setting is disabled by default. NCR Gold Drivers are
enabled in this setting by selecting:
Start, Control Panel, Power Options, APM tab and check the box
Enable Advance Power Management Support
Click Ok to finish.
ACPI
The 7401‐46xx terminal BIOS supports Advance Configuration Power
Interface (ACPI) 2.0 power management. Primary differences between
APM and ACPI are as follows:
• On an APM‐ managed terminal, the BIOS determines when to
switch between power states and also performs the switch. When
using ACPI, the operating system determines when to switch and
informs the BIOS to perform the switch.
• APM must be enabled in the BIOS. ACPI is automatically active
with the operating system.
• ACPI Setup options are available in the OS Control Panel.
Refer to the table in the ACPI section of “Chapter 2: 7401‐2xxx and 3xxx
Product Overview” for a comparison of the operation modes (states)
supported by APM and ACPI power management.
