Why is my MacBook not turning on?
The MagSafe connecter does not even light up, and the MacBook just won’t turn on. This happened after we left a disk in the drive after we turned it off.

The disk left in the drive is probably nothing but a coincidence. To troubleshoot a no green light try first disconnecting the battery and plug magsafe back to see if that changes picture. If it doesn’t, you will have to make sure you have a working magsafe first, then check the DC-in board to be on the safe side..both are relatively cheap and easy to replace. If nothing changes the situation a faulty logic board is very likely.
