Thanks for the suggestion. The only "power management software" that I
have installed is the cpufreq ondemand governor, which shouldn't use the
power saving modes AFAIK.

I have logged the CPU temperature, remaining battery capacity, charger
state and loadavg every 10 seconds, and the CPU is mostly idle (0.00
loadavg, ~40 °C), the battery full, and the charger connected. Then
suddenly, after ~15 hours, blinking keyboard lights and finally power off.
