Hi,
Here is s link to the service manual for your laptop.
Scroll to p.41 to view the pre-requisites and then the procedure to remove the display. Following the procedure by p.44 you will have reached the section that deals with the hinge removal.
On p.18 you will find the part number for the hinges, (809827-001), should you need to replace them.
If you search online using just the part number only you'll get results for suppliers of the part. The image shows what I mean.
(click on image to enlarge for better viewing).
Hopefully this is of some help.
