Windows – Computer wakes itself few seconds after hibernation

64-bitdell-optiplexhibernatewindows 7

This is the situation: this is a Dell Optiplex 755, I recently upgraded it to Windows 7 64-bit, 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.
