--- Comment #45 from Hans de Goede (jwrdegoede@fedoraproject.org) ---
I believe that your models simply do not have an ALS sensor.

Luya did also test the magnetometer and gyro bits and reported his results in
the Fedora bug about this:

Where I assume successful for the magn device means that the values changed
when doing the following: "For the magneto values (compass) you expect the x
and y values to change if you sit the laptop on the desk and then rotate it
while keeping it sitting on the desk, while the values should stat more or less
the same when you do not move the laptop."

@Richard, can you confirm that your model behaves the same, so working
accelerometer and magnetometer, with the gyro and als always reading all 0 ?

I would like to know, so that I can use the right sensor_mask for the DMI quirk
for the upstream driver for this.
