Why does my computer wake up at night?

Question

Windows

I put my computer in standby mode and go to sleep. I wake up in the morning, I press the power button, it wakes up from sleep mode. The time to check for updates in windows is at 14:00. In Device Manager, all the checkboxes "Allow this device to wake the computer from standby" are unchecked. In Power Options, "Enable Wake Timer" is set to "Disabled". In the event log, I see many events that occurred between 7:31:00 am and 7:31:45 am. Sources and codes:
Kernel-General (1), Ntfs (55), BTHUSB (18), Service Control Manager (7036), Power-Toubleshooter (1), Kernel-Power (42).
I open Power-Toubleshooter (1):
"The system has resumed from sleep mode.
Time to enter sleep mode: ‎2015‎-‎09‎-‎27T04:31:16.250157300Z
Wake-up time: ‎2015‎-‎09‎-‎27T04:31:15.655123300Z Exit
source: S4: Hibernate"
Open Kernel-Power (42):
"The system is going to sleep.
Reason for hibernation: Hibernation from hibernation"
OS: windows 7 Ultimate
WHAT IS GOING ON HERE? Help.

Answer 1

Try putting a minute delay in sleep mode. Perhaps the fact is that the mouse reduces power consumption, and the change leads to the exit and sleep mode.

Answer 2

Having seen such logs, I would begin to look at the settings of the hibernation timers and the state of the "enable hybrid sleep mode" parameter.
On my stock Asusov seven, it is rare unpredictable.
