Galaxy Tab S 8.4" Randomly Shuts Off

Hey all. I've got a Samsung Galaxy Tab S 8.4" that I've had for a few weeks now. I got it at work (computer shop) from my boss as a trade for an old computer I had. He got it off a customer so I have zero idea what the previous owner did with it. There is a dent in the top left corner that seems to have bent the frame of the device ever so slightly. The back cover has a very small gap in one spot and the screen has two hairline cracks. Otherwise the device looks new.

I've had it shut itself off a handful of times since I got it, two times were nearly back to back. The screen will usually flicker/artifact and then the whole device shuts down. No real pattern to when it does it, although the first time was right as I launched a game. It always fires right back up though and runs perfectly fine otherwise. I don't use it that much and considering I got a $350 tablet for almost free I'm not terribly fussed if it's a bit finnicky. I would like to fix it if possible though.

From what I can guess, there's a loose connection somewhere. I did a factory reset when I got it, although haven't tried one since. I'm not opposed to taking it apart but wouldn't really know what to look for either. Thoughts?
 
Started doing it a lot more frequently and also get a faint flicker and then it would freeze up, but not shut down completely. Disassembled it, reseated battery connection, and retaped it with electrical tape as per advise I found online. Hopefully that works.

Edit: 2 days later and had zero flickering or shut offs. Pretty sure reseating the battery connection and new electrical tape on top of it worked.

Is it hard to crack those tablets open?
With the right tools... no.
That^. I snagged a few prying tools from work that we use to disassemble phones and tablets.
