OPTICAL DRIVE NOT FULLY OPENING

There are two ways toopen the CD drive door if the button just below the drive tray does not work.
Go to My Computer and right click on the drive and click on Eject.
If this does not work then you can manually open the CD drive tray by -
Straighten a paper clip and gently insert it into a tiny hole below the drivetray next to the Eject button. Push the paper clip gently until the drive traypops out, then pull the tray until it is fully out, then you can remove the CDdisc.
If you continue having problem opening with the Eject button, then the CD driveis faulty and needs replacing.
