Hi all, this is the situation, this is a Dell Optiplex 755, I recently upgraded it to Windows 7 64 bits, it had Windows XP SP3 previously, on XP I never had a problem hibernating the PC, now with Windows 7 64 every time I hibernate the PC it wakes it self after 5 or so seconds.

Here are the steps I already tried:

On Windows 7 I enabled the hibernation following this steps

• In the MoBo the sleep settings are on S3
• In the Mobo I disable remote wake ups
• I have disabled the remote wake up in the NIC
• When I run the lastwake command I get unknown device or something like that
• I already disable the wake timers on Windows
• I have the latest drivers from Intel, but I just found out that in the device Manager I get a warning sign on the "Intel AMT SOL (COM3)" device saying that it failed and windows stopped the device, I reinstalled the Intel drivers but nothing changed.

The only thing that I haven't touch is Intel ME in the MoBo but I don't if that could help and what settings are correct.

Thanks for you help.
