Server 2008 R2 - Allow UPS to wake computer?

  • 772

I have a single Windows Server 2008 R2 box that's on a generic Geek Squad battery backup. (That purchase was not my choice.) It shuts down fine when the battery hits a critical level, but I can't seem to figure out how to get it to boot back up when the power comes back on. I tried to follow the instructions as outlined here - http://wiert.me/2010/06/24/using-a-usb-connected-apc-ups-with-windows-server-2008-and-vmware-server-2-0/ - but when I go into the Device Manager and open the properties for the HID UPS Battery device, I get no Power Management tab, so I don't see an option anywhere to allow the device to wake the computer.

Any ideas?

  1. If the machine is shutting down, as opposed to going into standby or hibernation, then it wouldn't matter what the power management setting is for that device, because the machine is shut down. To power it back up, you need something at the bios level like a KVM or Wake On LAN. If these servers run Intel processors equipped with vPro, you can leverage that technology as well.

    As for why the Power Management Tab isn't there, I believe that's based on the device actually implementing power management settings, see this answer in addition to this MSDN page.

  2. Is your BIOS set to restart on power being restored? Some BIOS defaults to "remain off" rather than "turn on" or "previous state".
