I have an EM7455, which will power on with the LPM enabled.
at!pcinfo? State: Low Power Mode LPM voters - Temp:0, Volt:0, User:0, W_DISABLE:0, IMSWITCH:0, BIOS:1 LPM persistence - None
I then use the QMI command to set the “FCC authentication” as its called:
qmicli -d /dev/cdc-wdm0 --dms-set-fcc-authentication [/dev/cdc-wdm0] Successfully set FCC authentication
The device is then in online mode:
State: Online LPM voters - Temp:0, Volt:0, User:0, W_DISABLE:0, IMSWITCH:0, BIOS:0 LPM persistence - None
So far so good, is it possible to permanently disable this “feature”? I have another EM7455 which does not require this procedure, so it is possible somehow.
