Hi, my RPi is working perfectly and has been for some time. Recently I started building a weather station and connected a bunch of sensors to the pi. All the sensors were tested with a python program individually and they work. I shut the system down.
The next day, I booted up the pi and it hung with a blank screen and no disk activity for ages. I powered off, disconnected the power leads (5V and 3.3V) and then booted the pi. Everything worked fine. I reconnected the two power leads and the sensors are working again.
Why should the pi refuse to boot with the power leads connected?
Thanks fr your help.
John
