Microsoft announced Wednesday that people looking to save energy and reduce the environmental impact of their computer should turn off their screensavers. A Windows Vista PC running a screensaver consumes more energy than a PC in "Sleep" mode, according to a statement from Dean DeWhitt, the director of Microsoft's Windows Kernel team. In fact, the screensaver-running PC consumes the same amount of electricity as a 100-watt lightbulb left on around the clock for one year. That is about $80 in power that releases about 1,350 pounds of carbon dioxide emissions into the atmosphere, according to Microsoft.
Microsoft got the energy statistics on PCs from U.K.-based PC Pro Labs, which conducted an independent study on the energy consumption of Windows Vista vs. Windows XP computers in a work environment. Vista includes a "Sleep" mode, like on Apple computers, which pauses a PC for energy savings, but also allows users to "awake" the monitor and machine instantly to resume use. It is a modified combination of the "Standby" and "Hibernate" modes that were on previous versions of Windows platforms. Microsoft said the new mode could be useful to large organizations that require users to leave their PCs running, so that security patches and updates can be applied during non-business hours.
Correction: This story incorrectly described Microsoft's recommendation to turn off screensavers. It is Windows Vista specific. Vista's "Sleep" mode is a modified combination of the old "Standby" and "Hibernate" modes on previous Windows platforms.
With todays security software added and all the toy gimmick programs From the oem or added often unknowingly) loading in the background when a typical consumer CPU boots, sleep mode is more like "coma" mode," meaning when one often tries to wake it up, it won't and it will be locked, requiring a reboot.
I have BANNED sleep/hibernation mode from my cpus, they are either on or off.
Just put the monitor to sleep after a certain period of inactivity. Set the computer to sleep after a longer period, a few hours or whatever suits your needs.
I find this is best.....hit the MS key..(flag) and the letter L at the same time....(make sure you have no programs running...)...and then hit the power switch on your monitor. In the morning...I hit my monitor power button..and wiggle my mouse...τΏ- type in my password...and it takes 10 seconds....saves power...and is safe from the kids trying to get on my puter. oh...this works best if you have your user name password protected.
I recently built a new system with Vista. When my PC suspends, hibernates, or even the LCD sleeps, I cann't recover the system. The primary display (of two) stays asleep, and the only way I can recover the screen is to remote desktop to the machine and reboot the box. (Or remotely reboot the box, but sometimes I have apps open.)
For this reason, Vista is the first OS I've ever had to completely disable Power management on.

Obviously you have somethign wrong in your computer. Vista power management works GREAT on my machine, and sleep mode is fantastic (I resume from sleep in about two seconds, and can logon in five). Probably you have some odd driver (and I don't blame you, there are many drivers that are lacking) but I would suggest you keep an eye on new drivers to see if a new one pops out that solves the issue.

I only set Windows to turn the monitor off after 30 min of inactivity. Monitors, especially CRT's, use up as much or more than a typical desktop computer.
I keep my computer on 24/7, since I donate unused CPU time to the Folding project (details at folding.stanford.edu, join team #45623 - team Danno) in which millions of computers worldwide can contribute to solving important problems, such as finding cures to diseases. It does not slow down your computer, just puts idle CPU time to good use.
Keep in mind that such projects are indeed power hogs. A CPU doing intensive calculation can burn lots of energy, way more than your monitor does when active. For older CPUs that's not much of a difference unless you compare with sleep mode, since they do not consume as much power when working, and they don't save much when idling. But for a last generation CPU, number crunching power consumption is staggering, while idle consumption is an order of magnitude lower even if not sleeping. So keep in mind you are not donating idle CPU but active power consumption. You ade donating money on your electricity bill. Which is a great think, but only if you know you are doing it.
"Vista includes a "Sleep" mode, like on Apple computers, which enables a PC to hibernate for energy savings..."
Most Apple computers are not capable of hibernation, only suspend. The diference? Hibernation zero power, suspend some power. Only the newer laptops are out of the box capable of this standard Windows and Linux feature. Some of the newer destops can as well but this requires a hack...
I have to leave my computer running 24/7 to filter all the #@%$ing spam I get. Otherwise it takes me 15-20 minutes in the morning before I can get to the legitimate email messages. So sleep mode won't work.
PCs can "NAP" since MS-DOS,Desktop PCs shouldn't sleep every 10 minute
Who are writing these articles?
Even MSDOS had sleep capability if you added power.exe to config.sys. It is called "advanced power saving" and it is there since 386s.
Windows managed to hide PCs own power saving system from the user very effectively. If they defaulted the ATX power button to "Sleep" instead of displaying a stupid menu, PC people could get used to sleeping their computer when not in use for long time.
Yes, Desktop PCs aren't designed for short periods of sleep/ wake up. The hard disks and display actually goes top watts when they are firing up.
Of course don't use a CPU killer as "screen saver". Use a simple screen saver or even "windows logo". Set your monitor to sleep (stand by) after 20 mins of idleness. Set your computer to sleep after 1 hour of idleness UNLESS you are connected to a corparate LAN, if it is the case: Ask your IT department for their policy.
Shame on you CNET, you are making me write on a Quad G5 Mac. :)
I would suggest when not using the compuer then block any internet activity with Zone Alarm Free or Kerio firewall. This shuts off your connection with the net yet allows the computer to stay on. You have to just simply click the taskbar icon and select Block Internet activity. The when you come back later to use your machine, then just click to once agin open your connection.
I have found that using the shift key does a better job of waking a sleeping computer than the old mouse wiggle, which worked fine until Vista came along.
Oh I'm perfectly aware it's likely a driver problem, and it's likely the Nvidia Drivers. That doesn't absolve Vista from not being absolved of the blame as well. XP's drivers work fine on this system. I'm just saying, those that build their own PC's had better be prepared for early adopter issues.

The rise of Apple's stores is one of the past decade's great retail stories. So, why then does the company continue to creep back into the big-box outlets and will this hurt the brand?
The company helps small businesses with little tech savvy build apps easily, and now its partner Constant Contact will email-blast prospective users, too.
