Hi Basukito,

Thanks for posting.

You may wish to try Dell Spare Parts or third party auction sites for these.

Hi

Is there anyway to attach the photo? It ooks like a transformer (9pin) but i couldn't find the similar one around here.

Unfortunately the wiring diagrams and parts are confidential.  Since the power supply circuit is not customer replaceable, you would need to take it to a Dell Service facility for repairs.  You can contact Tech Support at 1-800-624-9896 or 1-800-288-4410, or you can initiate a chat session http://dell.to/2v4snVm
