Putting Energy Hogs in the Home on a Strict Low-Power Diet

Putting Energy Hogs in the Home on a Strict Low-Power Diet – New York Times

Microsoft says that it has overhauled energy management in its Vista operating system so that machines, by default, should go into a low-power state after 60 minutes of inactivity. The PC sips only a few watts until the user touches the mouse or keyboard. To configure a machine with Vista, type “Power Options” in the search box at the bottom of the Start menu and click on “Change when the computer sleeps.”All of this, of course, assumes that the systems are working correctly. When I first installed Vista on my PC, I configured it to go to sleep after 30 minutes, but it has been unreliable. Sometimes it fails to go to sleep, and at other times it fails to wake up. Sometimes I experience the worst of both worlds: the drives and fan are spinning, but the monitor is blank, and I cannot get the machine to come back to life without powering it down and turning it back on.

I spent numerous hours trying to fix the problem, including updating the BIOS, installing up-to-date versions of all my device drivers, checking to make sure there were no unnecessary applications running in the background and, of course, scanning for spyware and viruses. The results were encouraging. After all that fiddling, the machine went to sleep most nights and woke up most — but not all —mornings.

I then installed Co2 Saver (co2saver.snap.com), a free program for Windows XP and Vista that seems to have solved the problem. It gives you a simple control panel to specify when to turn off monitors and disk drives and put the machine to sleep. It also adjusts some hard-to-configure settings. One option forces the machine to “Initiate sleep mode if system doesn’t sleep automatically.” This feature, according to its developer, Lee Hasiuk, defeats Windows attempts to keep a machine awake if it thinks (correctly or otherwise) that it is detecting a background task other than mouse or keyboard activity. Now my machine sleeps and wakes properly almost all the time.
