Dell Studio CPS 1340 will not enter hibernation...
I can get it to enter S3 just find but S4 will not work. I have checked the control panel power options. I have run powerconfig -h on. I have tried ending every non-essential process and service to see if one of them was causing it. Still didn't work. I have tried re-enabling the paging files (I had it disabled to save battery power). Still nothing. I could not find a hibernation file on the hard drive. There is plenty of space for it. Even typing powercfg -h -size 100 did not work. I have tried reinstalling my graphics card driver. I have checked the BIOS, still nothing. I just can't seem to figure it out. Has anyone else had a problem like this. I am running Windows 7 x64.
