DC LED light stays on after DC power removed if serial cable is attached - tpaul - 04-15-2023

I've noticed that the DC LED stays illuminated after I've disconnected the DC barrel power completely, but only if the serial port is still attached (just GND, TX, and RX via a USB Serial adapter.)

Are these pins also leaking power as mentioned here for the A64+? I use the EXP pins on my A64+ plus but they are absent on the RockPro64.

I intend to leave a serial connection attached to this board permanently so just want to ensure it's not going to cause damage long-term or if there's any way I can prevent it.
