Sony Vaio laptops equipped with a media disc tray can play back individual CDs and DVDs as well, on models equipped with a multimedia disc drive. If the tray fails to open in the usual way, by pressing the eject button in the centre of the tray door on the edge of the laptop, you can try troubleshooting the mechanism and possibly spare a repair bill or outright replacement of the drive.
Press the eject button on the drive door, which is on the right edge of the Vaio, and check the LED next to the button. The LED on a Vaio laptop should illuminate to indicate the drive is working. If the light does not come on, the drive may be disconnected inside the laptop.
Shut down the Vaio laptop, restart, then press the eject button. Restarting the computer may unlock the drive.
Bend the wire on a paper clip so it is straight as possible.
Insert one end of the paper clip straight into the hole on the far right side of the disc drive door cover. Push in the end of the clip as far as it will go to engage the emergency release, which should eject the tray if a disc hasn't become lodged inside the mechanism.
