As the CD/DVD drive is unable to eject the disc even through the emergency eject, it seems that the drive has gone bad and needs to be replaced.
You may run the hardware diagnostics to ensure that no other part is failing. The steps to run the diagnostics are listed below:
1. Restart the system.
2. Press F12 at Dell logo to enter the ‘One Time Boot Menu’.
3. Navigate to ‘Diagnostics’ using the Up/Down arrow key and press enter to launch the diagnostics.
4. Write down any error code that you receive during the diagnostics. Let me know the same.
I am sending you a private message. Please reply with the Service Tag of the system so that I can check the status of warranty on the system. Also provide me with the full name, phone number and the address of the original owner for account verification purposes.
Please reply in case of any issues. I will be glad to help.
Thanks and Regards,
