Debian Hardware :: Laptop Shutting Down (unrelated To CPU Temperature)

My laptop is frequently shutting down while using Google Earth 7.1.2.2041-r0. It uses 100% CPU, but only on one CPU core, and the problem happens at random.

I don't believe it is related to the CPU temperature, because I created a script that saves the current temperature every two seconds, so when the system shuts down I can see the last, and the highest I got from all the times was 62 °C, while the average from all the times it shut down was 57 °C from /sys/devices/platform/coretemp.0/hwmon/hwmon1/temp*_input and 51 °C from /sys/devices/virtual/thermal/thermal_zone0/temp and /sys/devices/virtual/hwmon/hwmon0/temp1_input. From my research, I understand that coretemp-0 is the temperature of the CPU itself, while the others (acpitz-virtual-0) are from underneath the base of the CPU.

The files under /sys and the command `sensors' tell me that only 80° would trigger a shutdown. I bought this laptop in 2013, and I have never seen it go beyond 6-°C:

Code: Select allsensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +41.0°C  (crit = +104.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +48.0°C  (high = +80.0°C, crit = +90.0°C)
Core 2:       +47.0°C  (high = +80.0°C, crit = +90.0°C)

I have done a simple stress test by running `cat /dev/zero >/dev/null' on 8 terminals, together with `glxgears' and `supertuxkart' for half an hour, and my system did not shutdown, neither the temperature went beyond 6-°C. The HD temperature lives around 42 °C, according to `sudo smartctl -l scttemp /dev/sda'.

The output from `inxi -F':
