Windows Utility For APM Driver V1.01

(C) Copyright IBM Corporation 1993.

This utility works in conjunction with APM Driver which provides power

management for both DOS and Windows.

It allows you to configure the APM Driver for your power manageable display to

your preference and convenience.   Your display must conform to the VESA

(Video Electronics Standards Association) DPMS (Display  Power Management

Signaling) interface to use all of the features of the  APM Driver.

IMPORTANT NOTES

The DPMS Support Enabled box will reflect the DPMS support of your

display.  If not , you can set it to reflect the real capability of your display.

The three time out groups:

        Standby Timeout

        Suspend Timeout

        Off Timeout

allow you to disable each of this power saving state or set a time out value

or to put the display into that particular power consumption state immediately.

By default, the time out values will be set to:

    STANDBY	15 minutes

    SUSPEND 	30 minutes

    OFF 	60 minutes

This means that if the user does not touch the keyboard or mouse for 15

minutes then the display will go into STANDBY mode. 15 minutes later it

will go to SUSPEND mode. 30 minutes later it will go to OFF mode.

Whenever the user presses a key or moves the mouse, the display will

return to ON.

ON is the only state where the screen is not blanked.

The user can set each of these timeout values from 1 to 99 minutes.

See your display documentation for suggested values to use with your

particular display.


IMPORTANT NOTES

1) If your display is power manageable, you should never use the XGA-2 2.1

     DMQS file with XGA-2 2.02 Display Drivers. You will not run into this

     inconsistency if you always install these files using the install program in

     XGA-2 Device Driver diskette.

2) If you install XGA Display Drivers V2.02 and you have a power manageable

     display, the right way to enable the power saving capability of the display is to

     set the "DPMS Support Enabled" box to checked, exit Windows and reboot

     your system.  However,  remember to uncheck  the "DPMS Support Enabled"

     box  when you are changing to a NON-DPMS support display.

3) If you are in any of the power saving states, press any key or move the mouse

    to bring the display back to ON state.  Note that the key uses to bring back

    the display will be effected so try to use key that usually don't cause any

    action, for example "Shift" key, "Ctrl" key. Moreover if you are in Windows

    full screen DOS prompt, DON'T use the Ctrl-Esc combination key to bring

    back the display as this will put the display into an erroneous state.


APM

The abbreviation of Advance Power Management. It is referring to the

APM V1.0 specification defined by Intel Corporation and Microsoft

Corporation.


DPMS

The abbreviation of Display Power Management Signaling. This signaling is

defined by Video Electronics Standards Association(VESA) to enable the

display to enter various Power Management States.


ON

ON state

This is the full powered state and the only state that the display will have

screen output shown.


STANDBY

STANDBY state

The STANDBY state has minimum power saving, but immediate return to ON.


SUSPEND

SUSPEND state

The SUSPEND state has medium power saving and medium return to ON.


OFF

OFF state

The OFF state has maximum power saving, but some noticeable delay in returning to ON.


DPMS Support

DPMS Support Enabled

This box specifies whether the display supports DPMS which allows the display

to be set to different states of power consumption.

It will be checked if the DMQS files of XGA-2 for the display you are using

specifies that the display has DPMS support. Otherwise it is not checked.

The box will reflect the true display DPMS capability only if your system is

installed with XGA-2 2.1 Driver and DMQS files.

However if your system is installed with XGA-2 2.02 Drivers and DMQS files,

the DPMS setting will always be shown as unsupported in the DMQS file even if

your display does has DPMS support and the box is not checked.

In the case where your system is installed with XGA-2 2.02 and your display does

has DPMS support, you can set the box to checked and the APM Driver will

put the display into power saving states according to the time out values you set

for each state.


Standby Timeout

 This group allows you to disable the STANDBY power saving state or set a time

 out value for this state or enter into this state immediately.

 When the "Disable" box is checked this state is being disabled and the APM

 Driver will not ever put the display into this power saving state.

 If the state is not disabled you can specify the period of mouse or keyboard

 inactivity at the end of which the display will be set to this state.


Off Timeout

 This group provide the same functionalities as in "Standby Timeout" for the

 OFF state.


Suspend Timeout

 This group provide the same functionalities as in "Standby Timeout" for the

 SUSPEND state.
