Debian Laptop Hard Reset Symptom Verification

To confirm a 'hard' reset, inspect the system logs immediately after a reboot by running 'journalctl -b -1 -e'. A hard reset is confirmed if the log shows no kernel panic, error messages, or shutdown sequence, but instead ends abruptly at the moment of the crash, followed by the start of a new boot cycle. Verifying this using 'last -x | grep -C1 "shutdown\|reboot"' which shows two consecutive boot events without a preceding clean shutdown sequence further confirms a power-level hardware interruption.
