Laptop screen blank after closing cover - !@#$%^(*&^ update

I truly DESPISE Windows 10 updates.....

My wife, on her Toshiba Qosmio laptop, running Win 10 Home, which has been running PERFECTLY FINE for months, GOT some kind of update early today. I haven't seen it so I'm not sure what it was, but it was "something with a number"...

Since it wanted her to let it update, she did.

Since then, ANY time she closes the lid, when she reopens it, the screen is blank gray. Mouse moves but there's NO display... I thought MAYBE it was some incredibly stupid new thing being done when it sleeps, so I went into the power settings and changed EVERYTHING to NEVER SLEEP. EVERYTHING.

Close the lid, open the lid, blank screen.

I have to reboot the thing every time she closes the lid.

Again - it has worked PERFECTLY for months. Update. NO MORE WORK. What do NOW?

Thanks for the thought, but nope... I went in, turned off Fast start. Turned off hibernate. Turned off sleep. Turned every EVERYTHING I can think of......

BUT, if you close the lid and open it, even after a couple seconds, you get the empty screen. It's not a BSOD, or even a BLACK screen, it's just blank - it's the sort-of black you get during part of the boot... The MOUSE is still there, you can move it around, click on the nothing, but there's no display........

My wife says it was the "Creator" update? I haven't seen it on my desktop yet, but apparently it attacked her laptop yesterday. And WHATEVER it did, it's causing me a LOT OF GRIEF 'cause she keeps having to shut down the whole laptop every time she walks away and closes the lid....... And at LEAST every third time, she TELLS ME she's still having to do it...

What the hell did Microsoft do THIS time? Somebody, anybody?

Awesome idea. Unfortunately, this laptop is a couple years old and uses an NVIDIA 360M processor and the 381.78 hotfix won't install.

It already has the most current drivers for this controller, which as far as I know is 342.01, so I believe it's current.

Still get a blank screen any time I close the lid. Mouse there, screen blank.

I figure this HAS to be something obvious but I"m not seeing it...

Unfortunately, everything on this thing is already set to do nothing. I just rechecked to be sure I didn't miss anything, and made sure - no sleeping, no hybernating, no shutting off the display no nothin'...........

SO, both of us being out of patience, I grabbed the Windows 10 CD I created when they started offering W10 in 2015 and told it to blow everything away (there wasn't much additional software installed on here), format the partition and install...

Which MAY work fine though I got the activation screen, tried the original Windows 7 code, which it rejected, tried the Windows 8.1 code, which it ALSO rejected, and finally hit "Skip" because there WAS NO "I don't have a product key" at the bottom...

SO, it's installing but I have NO idea what kind of hissy fit it'll have trying to activate the copy of Windows 10 Home that's been running on this laptop for almost 2 years..... I checked the Internet, but found a lot of wildly contrary information about needing/not needing product key, automatically activating the first time it hits the Internet since it was working before, and SO ON... Since I'm committed now to doing the install, can anybody tell me how to make SURE this thing is going to work without a lot of BS 'cause I do NOT want to go through another week of dealing with an annoyed domestic associate?
