UPS support in Windows 2008 Svr. std.

Hi,
we installed a new W2k8 server, connected our APC UPS and can see it in
device manager. Since we couldn't find a place where to set battery run time
adjustement we googled and found a hint that it could be found under energy
options, advanced monitor settings. No such luck. There is no tab that allows
us to adjust the battery run time of the UPS. Another post in another forum
said there would be now way in W2k8 to set these adjustments and we had to
use Powerchute. We have Powerchute but would prefer the slim setting like in
W2k3 to the bloatware from APC.

Can anybody she any light on this?

Thanks
Wolf
