One morning after leaving my Acer laptop (Predator PH315-52) plugged in with the lid closed overnight (as one does), I noticed it was powered off and completely unresponsive. No basic troubleshooting steps would get any response, including attempting to power cycle, unplugging the battery and holding the power button down, trying to boot with no battery and just the power connected, nothing. No charge light turned on when plugging in, no fans or lights came on.

I tested the adapter and found 19.8v coming through, so that’s not the problem.

Testing the points in the image below, I found that I had 19.8v right at the power input, through the first two capacitors, and at the beginning of the two smaller capacitors circled in pink. At the other side of the small two capacitors I had no voltage at all.

Testing a few other areas, I found some more spots that registered 19.8v, one spot that registered 3v, and the entire rest of the board registered 0v. It seems to me that the issue is with the two small capacitors circled in pink, but I’m not a computer repair guy so I don’t know.

I’m looking for any advice. Is this fixable? Is there more troubleshooting I can do to narrow down the issue?

That may be normal. Direct current doesn't go thru capacitors. They may simply be added filter caps. So one side would go to ground and the other to VCC.
My guess it that chip with the 3V is a regulator that takes the 19.8 V down to some smaller voltage. 3V seems low to me, but don't take my word for it. It looks like there's a part number on the chip. Look it up and see what it does.
