Windows 7 wakes automatically from sleep mode

I've been having problems with Windows 7 64 bit Professional waking automatically from sleep mode. If I put the computer to sleep and come back several hours later, it is always awake. I tried disabling the ability of the network adapter, mouse, and keyboard to wake the computer, but it still wakes on its own. I also ran "powercfg -devicequery wake_armed" in CMD and it doesn't display a single device. Is it possible for a running program to wake Windows, and if so, is there a way to figure out which one? I want Windows to wake only when I push the power button.

You are seeing a bug reported many times by some users. They are all using ACPI and 'chipset' drivers that need updating for Win 7 to successfully use the sleep function.
