Computers suck a lot of energy, as do the peripherals connected to them. Even when turned off, all devices draw at least some current. It's a trickle, but it adds up. First, the setup: I have a HP running Vista 64bit with two 19 inch monitors, a printer, speakers with subwoofer, cable modem, vonage router, and wireless router. The goal: When the PC shuts off, keep the cable modem, vonage, and wireless router still juiced, and completely kill the other peripherals... I don't want them drawing any power at all. Even better goal: not have to turn the PC off at all to make this happen (because PC startup takes a while). Even better: only a few minutes after I finish using the PC, have it shut down such that all peripherals are invisible to the grid, and with a mouse click, have everything back up within 10 seconds. No data loss, either, obviously. At home, here's how I contribute some treehuggin granola and lovin' to Mother Earth. Some time back, I heard of the Smart Strip power strip, a strip that enables a "controller" outlet to effectively cut off power to all other plugged-in devices when that controller itself is turned off. Seemed like a reasonable idea, so I bought two: one for my TV/devices and one for my computer. I'll focus on the computer with this post. I have the computer plugged into the control outlet. Monitors, printer, and speakers are plugged into the "controlled" outlets. Cable modem, vonage, and wireless router are plugged into the "always hot" outlets. Thus, when the PC is "off", the big-energy-sucking devices go dead while the ones I need to have on stay active. That's part 1. Some pics This is all well and good... turn the PC off, and save some money and some trees. But that's not good enough. I want it to be brainless... I don't want to have to turn off anything, and I don't want to have to wait a few minutes for everything to boot back up. I want it to happen automatically, and have my entire "state" retained when it comes back up. So, on to Part II of how I'm saving the world. "Sleep" to the rescue. Now, back in the XP days, I remember sleep flat out sucked. It took forever to come back up, often longer than it would've taken to shut down and restart the PC. With Vista -- at least in my experience with this particular PC, sleep is quite good. I have my power options set to turn off the monitors after 5 minutes of inactivity and Sleep the computer after 10 minutes. Thus, 10 minutes after I walk away from the thing, my state is retained and everything "shuts down". All earth-melting peripherals are off the grid. Angels weep at my magnanimousness. Babes swooooon. Now, some latte-sipping hypermiler choad is saying "But that's 10 minutes! What about the Northern endangered spotted Newt! You're killing the Newt you paint-drinking techno-earthkiller!". OK, I'll grant that in those 10 minutes, multiplied by say 10 times a day or whatever, I'm not winning any Al Gore Humanitarian awards. So, on to Part III, for the Prius set. In Vista, you can control what the "power" button does. That's the little round thing with the bar up the middle. I have it set so that when I hit the power button, the computer goes to "sleep". This is not windows XP sleep. This is Vista sleep (again, at least on my PC). And it shuts down within about 5 seconds, and when I wake it back up with a single mouse click, it's ready to roll in about 5 seconds. Full network connectivity takes somewhere between 15 and 30 seconds to reestablish. I know it's back up when TweetDeck chirps. Now, I did hit a snag initially with keeping the router Hot. The PC would sleep, but then it'd come back to life a second or two later. I had to go into device manager, find the network controller, right click and select "Properties", go to the "Power Management" tab, and Deselect "Allow this device to wake the computer". Bottom line: for me, the Smart Strip + Vista + Power Options + Sleep-on-Power-Button combination has been a win.
