Hi @shujat

Please try the following methods:

1. Please check if the CN14 is properly connected.
   You can try unplugging and reconnecting it.

2. Please check if the RTC battery still has power. Use a multimeter to measure the voltage at CN14.
   The voltage should be approximately 2.8V or higher.

Best Regards,
