Problems with PowerManagement_ForceSystemPowerDown (Powerdown sample)

Hi everyone.

I have problems with the Azure Sphere Powerdown cycle; even using your sample code* : .. /Samples/Powerdown

I seems to does not matter the time that I passes as a parameter to the function

`ForceSystemPowerDown(unsigned int maximum_residency_in_seconds);`

on line `static const unsigned int powerdownResidencyTime = 600;`

The time durring which the app is in low voltage (Powerdown) is only 30 seconds. afther that the device reboot

I have tested it with 2 boards : the Seeed MT3620 Mini Dev Board and the QIIO q200.

Do you have any idea how to fix this bug?

Thank you very much, your help will be greatly appreciated.
