My new 15inch shut down twice this morning and I just got it 3 days ago. The batter is fully charged and not sure what is happening, no warning nothing.
Is there some event that registers for me to look at to find out what caused this?
You can try these three things.
1) Open the Console app and see if you can find any weird discrepancies that may have caused this. (If you're not very savvy and just want to fix this proceed to number 2 and 3)
2) Open Disk Utility, select your hard drive, select "Repair Disk Permissions"
wait for that to finish. It will tell you when it is complete.
If that does not work then do this:
3) Shut down your computer. Then, press the power button to turn it back on.
Press and hold the D key before the gray startup screen appears.
It takes a minute or so for Apple Hardware Test to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
The AHT console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Note: Your test results will appear in the window in the bottom-right of the console.
To exit AHT, click Restart or Shut Down at the bottom of the window.

The above step will tell you if there is any issues with any hardware inside the computer.
If so, bring computer to apple store to get it fixed.
Remember, when in doubt- restore! Works for almost everything!
