LattePanda 3 Delta failed to auto-start

What I expect:

I would like to have my LattePand 3 Delta device auto-start after the following scenarios:

1. Power shortage --> Device off --> Power comes back --> Device auto-starts

2. Battery voltage drains below to the operational voltage --> Device off --> Charge the battery back to operational voltage (keep the battery connected to the device during this process) --> Device auto-starts

What I've done:

I modified the power management settings in BIOs, and set it to "Power On".

What is happening:

The configuration will handle scenario 1, which I mentioned above.

Doesn't work for scenario 2.

Questions:

1. The battery always connects to the device even when it is low voltage. Is it because the device couldn't recognize the state (voltage) changes and failed to trigger the auto-start?

2. Is there any way we can achieve scenario 2 via system setting/software?

3. Is there any way to achieve it via simple hardware adjustment?

I really appreciate any help you can provide.

Martin.
