CPU temp clamped to zero.

SUMMARY
Title.
The CPU temp sensor always shows 0.0°C.

STEPS TO REPRODUCE
1. Open "History" tab

OBSERVED RESULT
Temperature is always at 0.0°C

EXPECTED RESULT
It should match with acpi -V report, or at least be non-zero:

~ » acpi -V
Battery 0: Not charging, 79%
Battery 0: design capacity 4606 mAh, last full capacity 3701 mAh = 80%
Adapter 0: on-line
Thermal 0: ok, 50.0 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 103.0 degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 101.0 degrees C
