Is this an electrical or a scripting question? If it is a scripting question
then please elaborate.

I do not know if Server 2008 has a facility to switch between mains and
battery power under software control. If it has then it would be included in
WMI. The following WMI script does the opposite: It tells you if a machine
runs on mains or battery power.

Set oWMIService = GetObject("winmgmts:\\.\root\CIMV2")
Set cItems = oWMIService.ExecQuery( _
"SELECT * FROM Win32_Battery",,48)
For Each oItem in cItems
if oItem.BatteryStatus = 1 then
wscript.echo "Server runs on battery power"
else
wscript.echo "Server runs on mains power"
end if
Next
