So, a couple days ago, I shut down my 9570 and closed it up for the night. Same thing I do every day: start it up, do some work on it, shut it down when I go to bed. Next morning I hear the fans whirring from my laptop. Loudly. That's never happened before in the seven, maybe eight months I've had this laptop.

So, I open it up to see what it's up to; the screen doesn't turn on. So, for all I know, it's not actually doing anything but running the fans. I move the touchpad to see if that wakes the display. Nope, but curiously, the keyboard backlight comes on. I also notice the power light on my drawing tablet is still lit (Figured I'd share that detail in case it might be a clue). Next I press the power button to see if I get Windows or a boot screen; nothing changes. Screen does not light up at all.

So, I think to myself, maybe the computer's trying to burn off excess power or something? Silly thought, perhaps, but I had to go with my instincts in the heat of the moment. So next, I unplug the AC--thought maybe that would shut the fans off. Nope. Checked the touchpad one more time to make sure. Nothing happens, but this time not even the keyboard backlight comes on. Now I really have no idea what it's doing. My only immediate course of action is to hold the power button until the fans turn off. I hold it for ten seconds, and it eventually all shuts off. It hasn't tried to power itself up since.

What the heck was it doing? Did I just wreck my computer--or, did my computer just wreck itself? I recently read up on something called "static flea power," where disconnecting the battery and holding the power button for a long time is supposed to fix any unusual hardware problems. Could it hurt to try that? If I try to power the computer on now without trying that first, would that be a bad idea? If I'm greeted with a Startup Recovery screen, should I try to roll back to last month or run it with the current state? Does this have anything to do with Fast Startup--like, maybe it glitched up or something?

What's my next best move here?
