The Raspberry Pi 5 is the latest standout single-board computer in the market, so new that users are still discovering its peculiarities.
The default setting, POWER_OFF_ON_HALT=0, maintains continuous power consumption.
There is a simple and straightforward fix.
To implement the fix:
- Run sudo rpi-eeprom-config -e to edit the EEPROM config.
- Confirm the following settings:
[all]
BOOT_UART=1
WAKE_ON_GPIO=0
POWER_OFF_ON_HALT=1
- Save and reboot.
This adjustment reduces power consumption during shutdown from 1-2W to 0.01W or less. While the default setting addresses HAT compatibility, users can consider advocating for a universal default of POWER_OFF_ON_HALT=1.
Enabling this setting doesn't compromise functionality; the power button and red LED still operate, and the RTC maintains time for watchdog-related functions.
This simple configuration change enhances power efficiency!
