penalvch, thanks for addressing this issue so quickly.

I'm afraid there is no further information. The stickers only provide
the machine code and the serial number. The machine code allows for
precise identification of the hardware for Lenovo computers. Also in the
BIOS there's no information visible that is not printed here.

This is a Lenovo ThinkPad Yoga (S1, first generation), machine code
20C0003SFR.

Title:
  Accelerometer and light sensor only working after pm-suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My notebook has a built-in accelerometer and light sensor. Both are not working after normal startup, which I can confirm by the output of
  sudo gdbus introspect --system --dest net.hadess.SensorProxy --object-path /net/hadess/SensorProxy
  Also the automatic screen rotation does not work at this point.

  As soon as I go into suspend and return, I receive a valid output for
  both. The screen rotation then works fine as well.
