OK, here's some follow-up. The problem persists.

I have looked at the Registry Key referenced above, and the DWord BatteryTimeout, and when the problem is occurring the value is "7" which means 7 seconds. I manually change that to "0" so it never times out, and for a while it's just fine, and I turn it off when I want.

Then, out of nowhere, it starts dimming quickly, and I'll go back to that Registry Key, and it is reset to "7" again!!!???

What on earth could be doing this??
