Dear Khun Surachet
Thank you for contacting Dell Technical Support. I’m Nopadon Suvanmanee and good day to you.
Refer to your hinge tight, I have arranged for an engineer to replace the necessary part(s) for you. You will be receiving a call from our engineer within the next working day (Mon-Fri from 9am - 6pm) to schedule for an appointment and to have the system fixed. However, this is subject to part(s) availability.
Please let me know if you do not receive a call from the engineer by Friday. I will help to expedite the case for you.
I would appreciate it if you could update me on the status of this case so that I can know that this issue is resolved.
Should you have any further questions or concerns, please do not hesitate to reply my email. I will certainly do my best to assist you accordingly.
Have a nice day!
