Windows 7 Hibernate Options

I sometimes leave my desktop pc in hibernate mode overnight.  About 4:00 o'clock in the morning I discover that it has come out of hibernation and is in active mode.

What could be causing this?

I have a Comcast internet connection running on a Comcast Motorola Surfboard modem SB6120.   I use Comcast's Norton Security Suite for protection.

I prefer  not to leave my system in hibernate overnight, but sometimes I get distracted and forget to shut the system off.

Could  Win7 be responding to a Comcast internet diagnostic?

Thanks,
Howie

Windows updates being downloaded and applied.

Also, if someone has remote access to your pc, that would take it out of hibernation more.

Longshot: a hacker...  Are you running any anti virus?

Make sure your Windows Firewall is turned on.

Go to start, control panel, Windows Firewall... make sure it's on.

"... Windows downlload can wake up a Pc from hibernate? " => Yes and No.   No, there's nothing running that can decide to wake up the PC;  but Yes, the ACPI standard (power management) has a provision for a system setting timer to wake up at a specified time; and a timer in the chipset will cause that happen.     Windows does that for any scheduled tasks -- like automatic updates;  and other programs (e.g. Norton) may also have scheduled tasks (e.g. virus definition updates).

... You can, by the way, change your power configuration options so this is not allowed.
