| NetFn | 30h |
| CMD | 92h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, sub command=14h |
| 5 | policy option: option to be queried, which is newly added and compatible with the old one. 1-Fan speed enforce 2-elevation 3-Power Precapping to cooling |
