I didn't want to bore you with details...
Why I can be sure about the relation to the update is: it was standing on my office's desk, I did the update and after it was finished I closed the lid.
When I returned shortly after, I opened the cover, pressed the power button and there it was: the fans went on for a couple of seconds and nothing on the screen. Had to push buttons like forever to have it cold-started. That was when the issues started.
And I see it in the event-log that there are always several Type Cover driver issues. When I de-install that driver, the Feb.14 update appears again in the update list, so these must be related.
BTW: I LOVE re-installing computers. I'm maintaining PCs for all my relatives and I almost enjoy if they broke something, so I have something to fix (yes, I'm a pervert). But when it comes to the SP2, it appears just so pointless, it seems like fixing something which can't be fixed. However, since this time I seem to be alone with my issue, I might go for a replacement.

I've had a similar issue. Sleeping hadn't worked right until the Feb update, and then about a week ago, if I tried to wake up the SP2 from sleep using my Type Cover, this would happen. I uninstalled the "Surface Type Cover Filter Device", reinstalled it, and the issues went away for a few days. Then it happened again today. It seems to be related either to waking from sleep, or actually entering Hibernation when the Type Cover is connected.
