I did a search on the forum but did not come up with anything. What does the reset button do, exactly? Will I lose any data? Any setting? If so, which ones?

I am asking this because I want to get my camera to work, and the instructions in another thread involve pushing hte reset button—but they do not say what effect it will have on the rest of the computer.

AFAICT it’s just a reset button, like you’d find on any desktop.

No idea what it does but it magically fixed mine when it stopped powering up once.  Id hit the power button and it would turn lights on but no computer ... after asking on the forums someone suggested it and I tried it and magically it works. 

If you’ve ever delt with any PDA’s Id referr to it as something close to a soft reset that they use probably forcibly dumps temporary cache if it gets stuck for some reason?  But no files or anything lost after using it.
