Dell 2405FPW not powering back on with s3 standby mode

[KyleCanuck]

Hey folks, good to be back in the anandtech forums, its been years since I've actively posted anything. But I have a problem now and figured you guys would be the best to turn to.

I recently read an article in Maximum PC about enabling S3 power mode, and certainly its something I want to do for the environment as well as my monthly $$ bottom line. I have everything functioning, seemingly, as it should be. Fans and hard drives and CPU all shut off, and when I move my mouse it comes back on.

Everything that is except my Dell monitor. Nothing will get it to pull out of its low power/display off mode. Normally when it shuts itself off (not with the computer, just the monitor itself, my old power saving method) it powered back on instantly. Now nothing will get it back on.

Its connected via DVI to an ATI AIW 1900XL. I'm running winXP pro.

Any help or suggestions is GREATLY appreciated.

Thanks,

Kyle

Quick update,

My secondary monitor, which is my home theater's overhead projector, also does not re-power up after this standby mode. So my guess is that its a video card issue?

PS I do I have the latest drivers installed.

Yet another update:

I checked my bios and the setting 'Repost Video on s3 Resume' was set to No.

I changed it to read yes and saved the setting. Went back into windows and put the computer in standby mode. This time the monitors green light came back on, then off again, then it restarted the entire computer, both monitors working. This clearly is not how s3 power mode should work, as it was in fact a full restart.

I have a similar problem w/my NEC 2470 and 8800GTX video card. I checked the driver notes for the video card and it said that there is a problem w/the driver when the computer is coming out of sleep mode and the monitor may not turn back on. You might want to check to see if you have a similar situation.
