"APM Support" Exclamation Point in Device Manager

[Sylvander]

“Device Manager->System Devices->Advanced Power Management” has a yellow exclamation circle beside it.
“Properties->General->Device Status” says:
“This device is either not present, not working properly, or does not have all the drivers installed. (Code 10)”
“Try upgrading the device drivers for this device.”
I clicked “Update Driver” and searched my Windows disk for a more up-to-date driver and was told:
“The best driver Windows found is already installed for this device.”

I believe that this device is disabled because in the BIOS Setup, “Power Management Setup Menu”,
“Power Management : Disabled” is configured.
The PC was originally supplied with this setting and I’ve never changed it.
My display and HDD go into suspend mode and I can alter the delay at the “Display->Screen Saver->Settings” dialogue.

My motherboard manual says it can be configured for:
“Max Saving” where “Suspend Mode” is activated after 20 seconds.
“Min Savings” where “Suspend Mode” is activated after 40 minutes.
“User Define” where “Suspend Mode” is activated after a period set by the user.

Does anyone understand:
1. The significance of the BIOS versus the Windows settings.
2. Why these would be disabled in the BIOS for hardware supplied in 1997 with Windows 95.
3. What would happen if I set “Power Management : Max [or Min, or User Define]” in the BIOS.

You can use Apmstat.exe tool to determine the status of APM on the computer should be on the CD or you can extract the Apmstat.exe file from the Support.cab cabinet file.Once you have it Run the tool by typing the following line: apmstat -v For W/2000

Yeh, I'd already read this, but it's the more up-to-date version of "APM" and my BIOS does not support it since it was made in 1996.

My understanding so far is that the "Power Management" setting in the BIOS is a "Global" setting.
If it is "disabled" then all the other settings in the BIOS "Power Management Setup Menu" have no effect.
But it seems to be more uncertain than that.
Windows is still operating some level of power management even though I have it globally disabled in the BIOS.

So I'm wondering what will happen if I enable it and all the BIOS settings take effect.
The "Video Off Method" is set to "V/H SYNC+Blank" for example.
"PM Control by APM : Yes" is set.
"Suspend Switch : Enabled" is set.

SUCCESSSSSSSS ! ! ! !

All I had to do was ENABLE Power Management in the BIOS.

BIOS SETUP
POWER MANAGEMENT SETUP MENU

SETTING WAS
Power Management: Disabled

SETTING NOW
Power Management: User Define

The yellow exclamation mark is gone, everything seems to be working ok and "Standby" has been added to the "Shut Down" Menu.

Time will tell.
