I posted this in a Oct 7, 2006 message, but it is worth repeating again.
Here is an odd bit of information. Wake on LAN technology has been around
for a while as a green feature for PC's, yet until Microsoft SCCM (System
Center Configuration Manager) 2007 is deployed, earlier Systems Management
Server (SMS) 2003 required a third party solution to wake up PC's for
patches.

| SMS does not support Wake-On-LAN out of the box. However SMSWakeUp from
| 1E is an integrated product that provides this functionality:

| Q. Does SMS 2003 support Wake on LAN technology?
| A. Wake on LAN technology allows a computer to enter a
| powered-down or sleep state, but enter an active state upon
| receiving specific network packets. SMS 2003 does not
| currently include Wake on LAN technology, though there are
| some third-party applications that provide Wake on LAN
| within SMS.
I have always wondered why some corporate shops kept their
PC's powered up 24 hours a day, when there was potential to
save energy by putting them in sleep mode, to be awaken by the
server.
1.7 GHz PC at idle consumes approximately 60 Watts.
A corporate or educational campus with 1,000 PC's:
60 Watts/PC x 1,000 PC's x 24 hours/day x 365 days/year x .001
kilo-Watt-hours/Watt-hours = 525,600 kWh.
East Coast US cost of $0.125 per kWh nets annual cost of
$65,700 or 35,478 GBP required to keep PC's powered up
annually.
IMHO, apparently helping consumers save energy and reduce fossil emissions
is not a value added item to the corporation.
