Laptop failed to start up multiple times. Systemd won't get me to a login prompt. Dig around as best I can and it looks like a hardware issue. Open the case, remove the dust, fail to find anything in the obvious and easy fix category, try turning it on again before putting the case back, it's working flawlessly. Hopefully that continues to be true once I've finished copying some files off the encrypted drive, turn it off, and put the case back on.
