Windows 7 sleep problems

The sleep state problems that I have previously blogged about in Windows Vista appear to haunt the OS even in its new incarnation. It appears that the default behavior of Windows 7 (as set up in Redmond) is to enable ‘wake from sleep’ in all peripherals, including network card, mouse and keyboard. And for some reason all these peripherals send up some kind of signals that wake up the OS pretty much the very moment is has put itself to sleep state. Most irritating, making ‘sleep’ in Windows 7 totally useless. It took me a week or two to find out all the different devices that were sending the wake up signals, and disable them in the Device Manager > device properties. Here is a tip: you can save much time by going to ‘cmd’ prompt, and writing there ‘powercfg -DEVICEQUERY wake_armed‘. That should give you a list of the potential culprits for the sleep problems.
