Can you not partially disassemble it yourself and see if the connector has not just come loose? Though they may now solder it on to make it harder for home repairs and thus generate them more money.

If you're not confident in doing so, I'd check with an independent. It could be a much simpler and cheaper fix than Dell are suggesting.
