If it is a systemd based distribution, try "journalctl -b -1" which 
should show all the logs for the "-1" aka the boot before the current one.

It defaults to using the "less" pager, so press Shift-G to jump to the end.

The systemd journal has the same problem as most log files. If the 
system hardware actually failed, there won't be anything in the log, 
because it won't be able to write it.
