Summary of the HP/Phoenix BIOS
Power Saving and Ergonometry
Advanced Power Management (APM)
The BIOS is APM 1.2 compliant, providing it with facilities for
advanced
power management
(APM). APM is incorporated in Windows for
Workgroups 3.11, Windows 95 and OS/2, but not Windows NT. A file called
power.exe
is needed for APM under DOS.
APM is a standard, defined by Intel and Microsoft, for a power-saving mode
that is applicable under a wide range of operating systems. It supports the
following modes:
Fully-on
,
Standby
,
Suspend
,
Hibernation
and
Off
. Of
these, APM 1.2 supports
Fully-on
,
Standby
,
Suspend
and
Off
, as
summarized in the following table.
The
Suspend
mode is managed at the operating system level only, from the
Windows 95 Start menu. There is no longer the inter-activity between the
Setup
program and the operating system, and no longer a “sleep at” item on
the
Setup
program menus, to avoid the BIOS from shutting down the system
at the wrong moment.
RPO
defines a variation from the standard
Off
state. In
RPO
mode, the main
CPU hardware is off while a RPO function is powered by a power supply
called
VStandby
.
VStandby
is active as soon as the computer is plugged in.
RPO hardware can produce a triggering signal which turns on the computer.
