System goes to sleep when on battery (lid closed+external monitor)

[vaalbara]

The system instanly goes to sleep mode when I remove the power adapter:
- Lid is closed
- external monitor via HDMI

Is there a way to stop this? Apps like Caffeine did not help.

You can try to change the behavior in the Settings -> Lock Screen.

Pretty sure you can't if you remove the power.

Running the Terminal command caffeinate will prevent a Mac from sleeping regardless of what plugged state it's in.

Use Amphetamine.
