Hi
Yes this is repairable!
You can go 2 ways about it
1)take it back to dell for a repair
Or
2)buy a replacement part and install it yourself
Unfortunately there aren’t a ifixit guide on this specifically
And last but not least if you tell me in the comments what store you use(uk,us,eu…) I can help get you a link for your part
Hopefully this helps
Any questions please ask
Thanks:-)
