I received an ardx arduino experimenters kit (arduino uno and kool toys)
for Christmas. It worked fine and I spent part of a
day on 4 projects. This morning when I went to download a new program to
the processor I got a port not found error before I noticed that the green
power led was not on. I restarted my Imac and tried plugging the usb cord
into my ibook, but the arduino never showed. My ipod turns up fine on the
same usb port. I plugged the 9 volt battery power supply in and the power
light came on I tried connecting again via usb and no luck. Then I noticed
that the power light was off again and the battery was very warm.
Unplugging and replugging the battery results in the power led coming on for
about a minute before turning off. I assume this is the arduino/power
system protecting itself. Is there anything else I should try?

Re: Uno not powering up
Is there anything else connected to the Arduino?
Try just the Arduino via USB with no battery and nothing else connected.

Re: Uno not powering up
Imac>USB>uno was my original setup that stopped working. I tried adding the battery power after trying several usb ports on several computers with no green led.

Re: Uno not powering up
So, with USB power alone, the led does not come on. With battery power, it comes on for a short time and the battery gets warm?
Sounds like something is shorted. Are you sure that the back of the Arduino is not touching anything conductive?

Re: Uno not powering up
Playing around some more I found that disconnecting my circuit brought Uno back to life, so looks like I have a different problem now, thanks, and sorry to waste your time
