 Bigger Bigger  Smaller Smaller  Reset Reset

Hey,

it happend to me few times already and I am really starting to hate it. I have few Arduino Boards (UNO, Duemanilove, Leonardo), and all of them sometimes restart my computer when uploading the program.
I have Macbook Pro 13" mid 2010. No other devices are attached. Anyone has an idea?

Regards

That is one of the most bizzare problem symptoms I can recall reading about. Don't have a solution for you. Possible problems:

Flaky intermittent power problem with the USB ports causing a hardware reset in your Macbook?

It is indeed very weird. Sometimes the reset is immediate, last time the video I was watching started stuttering and than the computer restarted.

That sure sounds like a USB power problem in the apple's hardware to me.

Only when uploading?

What about verify (upload is not performed)?

No, only when uploading. I don't think this is a software issue.

The primary difference between uploading and not uploading is software.  Why would you believe that can't be the culprit?

I don't understand. It doesn't happen when verifying. It happens when uploading - during the 'uploading' part of the process.

The culprit might have something to do with the fact that the uploader sends a
Reset pulse to the Arduino, and there may be a fault in that ckt. Does the problem
still occur when powering the Arduino bd from an external supply via the power jack?

The time I had an Arduino bd resetting my notebook, there was a short from the
USB power pin to the external power pin. The PC would completely shutdown when
I connected the external power source to the bd.

Yeah, I know that might be an issue sometimes. But now the arduino wasn't connected to anything, powered from the computer. I guess it must be fault on the motherboard of the computer.

One of my notebook PCs does have a blown USB port, so there's always a possibility of
a fault there. However, I also asked

Not necessarily a fault, just inadequate power at the port. You are exceeding the specification. And it's not exclusive to your macbook either. I recently replaced the mobo in my desktop and was horrified to find it refused to start the next morning. It turned out that the Arduino was the culprit.
