To eject a disc
When you finish using a disc, wait until the LED indicator turns off, and then press the Eject button to remove the disc.
When the computer is in a power saving mode, you cannot remove an optical disc. See Controlling Power Management for
more information about power saving modes.
If the optical disc does not slide out when you press the Eject button, turn off the computer and insert a thin, pointed
object (such as a paper clip) into the manual eject hole.
Make sure to seat the disc firmly over the hub fingers. If you do not seat the disc firmly, you could damage your
optical disc drive and you may not be able to open the tray.
