Sleeper settings in Windows

[Fluno]

When I set a laptop to sleep in Windows it works fine unless it is in sleep state for several hours. At that point, it seems like it switches over to hibernate. I tried using the Sleeper program with S3 and checking the "sleep forever" setting, and with this, it stayed in sleep mode, instead of switching to hibernate. I am wondering if there is an equivalent setting in Windows, or maybe even a registry key that would accomplish the same thing. What is Sleeper doing different when it goes to sleep mode that Windows isn't doing?

Thanks much

You can disable hibernation by typing the following in an elevated command prompt:
powercfg -h off
(There is nothing being reported back to you afterwards, don't worry about that)

This will also remove the hiberfil.sys file (does not require a restart, usually this frees up space on C:\ equal to your amount of system memory) and remove the hibernation settings from the power options.

I disable hibernation for all workstations usually.
