RS480M2 resume from hibernate

[neceer]

I have been trying for some time to get my rs480m2 to resume from hibernate. I was able to do this with its original bios (I think 3.3), however when I installed a sata hd, I updated the bios to 3.8. Since then I have not been able to resume from hibernate, even if I flashed 3.3 back. When I flashed 3.8 I cleared my cmos and lost the original configuration, so have tried all reasonable bios combinations in power management with no success. If I manually set the day (of month) and time in bios, log into win2k and enter hibernate it will wake up without a problem. It seems that either windows does not write the RTC day, time values or the BIOS does not allow it. What conditions must exist in the bios or maybe windows for the RTC to get set from windows. I am currently using a program called Sleeper to initiate automatic resume with hibernation. Resuming from S3 works fine, but from S4 it does not. If anybody can recommend a different utility, one that perhaps allows direct access to the RTC parameters I could test if manually changing RTC from windows is possible and that the values are held after entering hibernation.

You want the thing to power on at a certain time of day?

That is correct, I remember I even shut the power bar off and then turned it back on before the timeout would occur, to test if any external power was necessary to it to work. With some motherboards it seems, you have to restart windows and then hibernate before the CMOS changes take effect. I don't remember doing anything like this before when it resumed from hibernate without a problem.
