- PC is set to S1 and S3 for ACPI in BIOS
- PC is set to 'Power Up' on AC return
- UPS is set to shutdown PC safely on Battery Low.
Bypassing the UPS, if I pull the power on the PC, wait then plug it back in.. the PC starts up (no power button press needed). This is the desired outcome.
Going through the UPS and having it set to 'shutdown the operating system' it safely shuts down the PC, however on Power return, the PC does not start up. Not what I want.
If I disable 'shutdown the PC' and let the UPS run until it runs out of power (battery discharges.. thus PC shuts off immediatley).. then re-apply power to the UPS, the PC starts up without a power button press.
Any Ideas? I can't find anything causing this. Prior to a reformat and reinstall of the OS and UPS control software, it was working as intended (would shutdown PC safely on low batttery and PC would start up when power returned).
UPS is a Fenton PowerPal 660. Control software is UPSILION 2000 for Windows. Yep, it's a cheapie UPS.
