Following your instructions I booted up with the power supply plugged in.

For the logs I used TLP_DEBUG="arg bat path ps run sysfs" in tlp.conf.

'get_sys_power_supply()' correctly reads AC status as offline, recognizes 'psrc_name' as ADP1, then triggers the MBP quirk. 'get_sys_power_supply()' moves on to check battery status. Battery status is read as Full/Charging despite AC being unplugged. We wait .8 seconds to check again to give batttery status time to update. Battery status doesn't change to 'Discharging' during the wait time so '_syspwr' is set to 0. 'power_mode' is set to AC.

Changed the wait value to 15 instead of 8.

The longer wait time allows for battery status to be updated. TLP now correctly sets the power mode to 'battery'.

Here is the log after applying the fix.
