TOPIC


    In Appendix C, pages 181-182 of the "PC Compatibility Card User's Manual for the 12-inch Card" it is stated that Display Power Management System (DPMS) is not supported with Apple's PC Compatibility Cards.

    However, it appears to work fine on my Power Macintosh 8500/120 computer with a 12 Inch PC Compatibility Card and an Apple Multiple Scan 15 display under Windows 3.1 and Windows 95.

    Is the manual wrong? After all, it does appear to work on my system.

DISCUSSION


    DPMS or any kind of power management is not supported with Apple's PC Compatibility cards. Power management control of any kind is intentionally disabled in ROM.

    When you set up and enable DPMS by using ATI Technologies' driver software, the energy saving features apply only to the monitor, not the PC Compatibility card. In other words, your monitor goes into energy saving mode (blank), but PC environment is still active.

    Even if DPMS works on Apple's PC Compatibility cards while running Windows 3.1 and Windows 95, Apple does not support it. Apple can only recommend using any power-management features in Macintosh environment.
