Argon one

How to keep argon one to always on
Power current will flow directly to Raspberry Pi. NO need to PRESS button to power ON from shutdown or power outage.

I used the code
i2cset -y 1 0x01a 0xfe

still it does not work


maybe you can have a look to following blog

On the bottom is a user discussion on your issue, looks like the power on feature is not working on newer cases. One user was describing some pins to be connected. But not sure.
