Usage of Advanced Power Management
BASIC APM SUPPORT
Source: TAIS via CIS
APM.SYS loads in your CONFIG.SYS file and, when loaded, makes the
following series of models APM compliant:
T1800, T1850, T1850C, T1900, T4500, T4600
There are no switches so it is simply installed by putting
"DEVICE=C:\DOS\APM.SYS" into the CONFIG.SYS file.
The following models have APM in the ROM BIOS so the APM.SYS driver is
not used:
T200, T1910, T1950, T2400, T3400, T3600, T4700, T4800
All future models are also expected to have APM support in the BIOS.
All models, whether using APM.SYS or with APM in BIOS, require use of
POWER.EXE as indicated below.
POWER UTILITY
POWER.EXE is the DOS 5.0/6.x APM power manager to reduce power
consumption when applications and devices are idle. POWER.EXE must
first be loaded in CONFIG.SYS as a device driver. Then can be executed
as a utility to vary settings in AUTOEXEC.BAT or at the DOS prompt.
POWER.EXE Syntax
----------------
Device driver usage (required)
device=[drive:][path]POWER.EXE [adv [:max | reg | min] | std | off] [/low]
Command line usage:
POWER [adv: [max | reg | min] | std | off]
To display the current power setting, enter "POWER" at a DOS prompt.
parameters:
-----------
adv [:max|reg|min]
Conserves power when applications and
hardware devices are idle. In some cases,
performance may be affected if an application is active
instead of idle. Use `max' for maximum power conservation.
Use `reg', the default setting, to balance power conservation
with application and device performance. Use `min' if the
performance of an application or device is not satisfactory
when you specify `max' or `reg'.
std Conserves power by using only the power-management features
of your computer's hardware.
off Turns off power management.
/low Only used in CONFIG.SYS file. Loads the device driver into
low memory, even if there is UMA available. By default,
POWER.EXE is loaded into UMA if the UMA is available.
WINDOWS 3.1 SETUP
Select the computer type of "MS-DOS system with APM"
Models that feature APM in the BIOS (see the BASIC APM SUPPORT paragraph
above) do not require the WRESUME.386 be installed via SYSTEM.INI when
the "MS-DOS system with APM" machine type is selected.
