Lenovo — Lenovo yoga 7i

The hinge of my laptop is broken. Am unable to move the screen .
I have taken proper and reasonable care of the machine and have not commited any mistakes, its a defect in the laptop itself.

I have 7 months of warranty still left but the Lenovo care centres are not cooperating.
I have already suffered from huge financial loss due to this issue, am not able to continue my classes too.
Even after being in warranty and facing losses, the Lenovo centre is demanding me money for the repair.
Why should I pay money if I have committed no mistakes and also the machine is in warranty .
