Thank you for the response.
I am glad that issue with the Inspiron system is being taken care of and technical support is sending an onsite technician to fix the system.
As the system was purchased in Ireland, I would request you to get in touch with the local support for getting a quick resolution for your Latitude system as well.

Please reply if you have any questions.
Thanks and Regards,
