@Raof,
As per Dell and Intel, here're some documents

1. Currently, Motion condition is not supported against v2.5.0 release.
2. A patch in WIP branch to have the partial support, Motion = 0: https://github.com/intel/thermal_daemon/commit/cc0890a5972575eee2ab778772b1ee9ae1c75dba
3. Some background of this “motion”:
 1) Per Intel document #607821, the Motion variant is to indicate the system put on the desk “Motion=0”, or it is carried on moving or it is put on the lap (Motion=1).
 2) For the Dell Latitude laptops, in the adaptive performance condition table (APCT), Motion variant is added for each condition_set.
Taking our current POC system for example, as you known, there are totally 8 condition sets, 7 of them are with Motion=0, 1 of them is with Motion=1.
If we do not apply above mentioned patch, the system will be working under the “highest power” mode which is defined in the APCT table, but could not switch to other cooler mode.
