Hi guys.

I have connected a power supply to the draws hat, but when I switch the supply on,

the Pi does not 'start'.

the cooling fans are working, I see the GREEN LED on the Pi illuminated continually, and do not

see the RED LED illuminate at all.

why would that be? the Pi worked / works perfectly when powered from its USB power port.

Thank you
