    I have a Dell laptop that has at various times run Windows 7 32-bit and 64-bit. A couple of months ago, under Windows 7 32-bit, the 'sleep' option disappeared from my system. Start -> Shut Down -> Sleep became greyed out. In power options, there was no longer a 'sleep' option in the lists of actions for the power button, lid, etc.

    At my IT department's suggestion, I reformatted the drive and installed Windows 7 64-bit (Enterprise edition). I added device drivers in the order called out in the Dell Reimage 'How-To' Guide, using the latest versions from the Dell Support website. I have the most recent BIOS for this system. Windows Updates are up to date.

    With all of this, sleep is still not available.

    I tried contacting Dell support. They were unable to provide a solution or much of a process for getting a solution (the tech asked me to contact him if I came up with a solution!).

    Sleep worked at one time, but does not currently work. Knowing that the system is capable of sleep, I'm guessing that there is a device driver that is preventing sleep, but I don't know how to go about determining which one is causing the problem.

    I've started looking for newer drivers than Dell supplies by going to the device manufacturers web sites. Updating the Intel LAN driver didn't help.

    I'm looking for suggestions for strategies for finding the reason that my system won't sleep and fixing it. Any suggestions?

    Thanks for the PowerCfg idea. It comes back with 88 errors(!), linked to \FileSystem\rdbss. A quick search shows that this has to do with files open on the network. For this problem, PowerCfg /requests is more useful, it gives specific information about each file open.

    Also, check out the latest Windows Secrets column under Fred Langa: "Is 'Sleep' the same as 'Suspend' or 'Standby'?"

    The devices seem to be Intel chipset devices - perhaps there's a missing driver for the chipset? Still digging...
