Self Reboot

I've noticed over the past months that my computer reboots itself on Thursday morning somewhere around 3:30AM. This is not every Thursday but when this happens it is always a Thursday.

This morning, my cat was sticking his nose in my face and woke me. I got up to pee and saw that my computer was on (it always goes to sleep at night) and appeared to be going back to sleep. However, when I finished my business, I saw the computer at the log on screen.

In the past when I awoke in the night I'd see the light from the screen but would go back to sleep. The only way I knew it rebooted was the absence of Keypass and the gmail prompt.

I checked the system logs. Only thing I saw was a Services Restart at 3:30AM. Seemed like W7 was doing routine maintenance. Does a SR reboot or is this something different?

Thanks,
Burt

There is only a weekly backup for Sundays at 7:00 PM. There is no info available in the logs other then a lot of activity beginning around 3:30. Nothing specific other than system logon stuff.

There is an important enough update delivered this week that will restart the computer instead of just asking you to Restart or Postpone. I know because I juggled it in my tray this morning while it kept counting down to restart.

Checked the update history and was notified that the system was updated at 3:01 AM today. Guess that solves the mystery.
