"Insert a Disc" Problem on Dell Inspiron E1405

Good day! 

After an improper shutdown yesterday due to a low battery, I have noticed that the CD/DVD drive (SONY CDRWDVD CRX880A) cannot recognized a disc. After inserting a good quality disc, the light indicator turns green for about 10 seconds, and then when i click on my computer to open the CD it displayed the following:

Insert a Disc

Please insert a Disc in Drive E:

and then the drive ejects.

Here are the other things I have done to fix the problem above but still not working:

-Uninstall / Reinstall the driver

-Tried different CD's / DVD's

- Clean the lens with a soft cloth

- Run the Dell Diagnostics (using a data CD) - Result: Error Code 0147

                                                              Msg error code 2000 - 0146

                                                              Msg unit 2 Optical Drive BIST - Spindel Test Failed

- Tried deleting the registry Upper and Lower

I only use the CD/DVD drive once in a while so I'm sure that the lens is still ok.

My warranty just expired a month ago and I,m from the Philippines so Technical support is kinda limited.

Thanks in advance!
