Computer wakes itself few seconds after hibernation

Question

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.

Restart? Have you checked the event log for any errors that happen when it hibernates? When a crash happens, the system can have an automatic restart process. If anything is waking up the system, it would return back to windows. Sounds like a bad driver somewhere. Can you enter sleep mode without it restarting? — Doltknuckle, Dec 08 '10 at 19:55
What i meant with restarts it's that wakes up without any user interaction, in the event log all I can see is that an unknown device waked the computer, I'll edit the question to avoid confusion — Juan Zamudio, Dec 08 '10 at 20:00
Most documents are written for laptops, and I cannot find one on Dell.com, here are some suggestions from HP...http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02076993&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN#N70 — Moab, Dec 08 '10 at 23:51

This might help:

right-click network icon in taskbar
open network and sharing center
change adapter settings
right-click your network adapter and choose "properties"
click the "configure" button
click the "power management" tab
un-check: allow this device to wake the computer

I think this should resolve your issue?

so I would file this under "disconnect all USB devices when troubleshooting sleep issues" – Jeff Atwood Dec 24 '10 at 07:00
