Computer restarts instead of shutting down after Windows Update.

[spqrobert]

I'm having a problem with my laptop. I run Windows 7 Professional 64bit on it. An hour and a half ago I shut down my computer and Windows installed an update, but I stuck around because I wanted my computer off and I know that the computer restarts itself after installing an update. The computer restarted itself and configured the update, but when I chose to shut down the computer it actually restarted itself. I've tried shutting it down several times, but every time it starts right back up. I've run a virus scan, the Power troubleshooter, disabled automatic restart upon System failure, and searched Google and Windows help files for similar-sounding problems, all to no effect. My attempts to fix the issue so far represent the extent of my comfort in dealing with computer issues by myself, so I found this forum and decided to ask for some help. Thanks in advance.

Are you shutting the computer down by pressing the power button or by using the start > shutdown method?
If it is by pressing the power button, have a check to see what the power button is set to do when pressed.
(Control panel > Hardware and Sound > Power options > Choose What the power buttons do)

If this isn't the case,
I've experienced this problem and fixed it by clearing the CMOS. (Removing the CMOS battery, leaving for 10 seconds, then placing it back in.)
