Will go into the BIOS on next reboot.

Any luck?

I checked in the system BIOS and there are two settings, ACPI was ON and
Power Management (off / minimum / regular) was OFF. I changed it in two
steps to Min, then Reg and the Display Properties, Screen Saver, Power
settings are still all greyed out. It looks like the UPS settings are
there on a separate tab which are totally greyed out too. Now seem to
remember installing a couple versions of BackUps software from APC.
Would that have any affect?

Have a utility called http://www.whatsrunning.net/ and ACPI is not
listed in any of the Processes, Services, Modules, or Drivers. Don't
see APM either.


The diver displaying name Dell P990 is loaded, which is "monitor8.inf"
as well. Where in Device Manager do I look for ACPI?


ACPI (or APM...two different methods of managing powers states in your
PC) It is a parent driver of your system, at the very top of the list,
under Computer, in device manager, most all internal devices are
children of it.

That your monitor drivers are installed is good, it makes reloading them
easier...reinstall them!

When you have all the pieces in place: functioning ACPI settings (best
guess..it is SCSI based), a prior known good state, present device
drivers, you should be back in business.

Ok found it.. the current driver/setting is "ACPI Multiprocessor PC".
ALso noticed the ACPI.sys file is compressed in the NTFS file system
(it has a violet color) and seem to recall that none of these can be
compressed? or is that nonsense? Yep.. the system is SCSI and the
monitor power-saver has worked before for a long time.
