pin sinking current at poweroff

Hello,

nrf_gpio_cfg_default should reset the pin configuration to its default state, which is input with input buffer disconnected. So, when input buffer is disconnected it should go back to reset state. You can set a breakpoint between vInit_StatLED() and sd_power_system_off() to observe if the LEDs are off before entering System OFF mode.

You can also check the GPIO peripheral pin configuration (https://infocenter.nordicsemi.com/topic/ps_nrf52811/gpio.html?cp=4_4_0_5_7_1_9#register.PIN_CNF-0-31)  to see that the pin (PIN_CNF) is set with the default configuration. PIN_CNF should read 0x00000002.
