Default Check engine (system malfunction indicator light)

This morning upon turning my ignition on my check engine light came on, I did a quick scan of the gas cap (which was fine) and read the manuel quick...it is not flashing so it said it's ok to drive, but still I'm a little worried...

Any one have a clue to what it could be??? Does that light come on as a oil change reminder???

I had that light come on, and it seemed the battery was a little weak at startup. I swapped out the original battery for an Optima and it went off and never came back on.
