# * Please carefully check whether your hardware installation is secure and if the pogo pins are making proper contact. We have had cases where customers found that loose brass standoffs caused poor contact with the pogo pins, leading to the low voltage warning.# * It may be caused by an OS update. Please confirm whether you have recently updated the OS or if your OS system updates automatically.# * Please run the command:<code>vcgencmd pmic_read_adc</code> and provide us with the result. Alternatively, use a multimeter to measure the voltage value of '''PIN2'''. As shown in the figure:[[File:X120x.png|700px]]
