Why IT Won't Power Down PCs
snydeq writes "Internal politics and poor leadership on sustainable IT strategies are among the top reasons preventing organizations from practicing proper PC power management — to the tune of $2.8 billion wasted per year powering unused PCs. According to a recent survey, 42 percent of IT shops do not manage PC energy consumption simply because no one in the organization has been made responsible for doing so — this despite greater awareness of IT power-saving myths, and PC power myths in particular. Worse, 22 percent of IT admins surveyed said that savings from PC power management 'flow to another department's budget.' In other words, resources spent by IT vs. the permanent energy crisis appear to result in little payback for IT."
Doubly so for IT Ops. If the business tells IT it wants PC's powered off when not in use, then it will happen. So far, for the most part, that businesses haven't asked. It's disingenuous to lay this problem at the feet of the IT department.

I worked as head of Critical Factilities Engineering for a major financial services provider with a 1 MM sq ft campus. There were just over 4000 employees on the campus, each one with at least 1 computer at his/her office/cube. After having a very expensive energy audit performed, a potential savings was (big surprise) shutting down PCs.
Despite calculating that the organization could save $75K annually (this was a conservative estimate), their marketing department put a stop to the idea. Why marketing? Because the company had just gone through a "rebranding" and the marketing department had designed a new screensaver for all workstations with the new logo/slogan. None of these computers were in client facing positions, so effectively, they were insistent on wasting energy to advertise....to themselves!
No, I'm not kidding.
I'm sure it has nothing to do with bad hardware or bad drivers that randomly refuse to wake up from hibernation and the hassles and expense of supporting related issues.
If a tree falls on an anonymous coward yelling 'first post' in the forest, does anybody hear?
As soon as I can apply a group policy to our Windows PCs to go to sleep yet still be available via RDP for end users without requiring them to jump through hoops or writing some script they have to run to trigger wake on lan, then I'll have our PCs use power saving.
Until then, they run all the time so when a user happens to be out of office and needs to access their desktop they can still VPN in and use RDP to get to their PC.
Feel free to point me at a graceful solution, but the best I've seen so far is a web page to send the wake on lan packet. Thats nice and all, but I'd rather just pay the power bill instead, its far easier than explaining it to everyone who isn't a geek.

I teach physics at a community college, and I recently made a big push to get proper power management set up in the science division's computer labs. It ended up being orders of magnitude more work than I thought it would.
I had seemed like a total no-brainer to me. We had 42 desktop Windows machines in our student computer labs. They were running 24/7. They had CRT monitors, and they were configured so that when they weren't being used, they ran a waving flag animation on the screen, meaning that both the CPU and the monitor were drawing full power. Here we were teaching our students about global warming, but we had this ridiculously wasteful configuration.
The first issue was that, as the slashdot summary suggests is common, nobody really cared, because it was some other part of the organization that was paying the electric bills.
The second issue was that when I approached IT, they wanted to handle it using software called Deep Freeze, which not only handles power management but also automatically restores the computer's hard disk to a known state every so often. This is in principle a good idea, because it means that students can't screw up the machines, and it's another layer of defense against malware. However, it opened up a whole can of worms, because if they were going to make this new hard disk image, they wanted to make sure it was done right. They wanted to update the OS, and install all the apps from scratch. Well, we had a ton of apps dating back to ca. 1995 that were still being used for instruction, but nobody could find the licenses for them. So that became a huge issue. It was one that we would have had to deal with sooner or later anyway, but it was a clear example where the easiest thing to do is always to leave things the way they are.
So we finally got that done, after much interpersonal conflict and hurt feelings. Now we have the new issue, which seems to be that Deep Freeze doesn't play nicely with Windows updates. In one lab, for example, we have about 60 machines, roughly half belonging to the science division. Their hard disks get reimaged over the weekend by Deep Freeze. But wait, then on Monday morning people walk into the lab and power up all the machines. Now all 60 machines phone home and realize that they need an update from MS; they had the update before, but it got erased by the reimaging. So they all start downloading the same 100 Mb update at once, with predictable effects. A chemistry teacher brings in a whole class to do work on the computers, and the computers are completely unusable. Oops, time to come up with a new lesson plan. Hope he's good at thinking on his feet.
Of course there's no reason in principle that all of these different issues had to be coupled together. E.g., Faronics, which sells Deep Freeze, has another product that only does power management, not reimaging. But the thing is, in real life you're dealing with complex systems and complex human organizations, and lots of well-intentioned changes can have unintended effects.
