Overnight the laptop decided to download some updates and turn itself off. Thismorning I thought "Ahhh, looks like I'll have to reload Windows." (The fingerprint reader wouldn't work, wasn't even prompting with sound to swipe the finger. Gimmicky, I know, but my memory is stuffed, and it's helpful.)
Well, the finger swipe worked.
I guess the lazy finger print reader's been re-booted, too. Good!
