My laptop's two hinges appear to have been damaged as the result of an accidental drop. It appears a certain part of the right hinge is bulging out. When lifting up the laptop screen, the sound of this part bulging out is heard. My laptop doesn't close tightly either; when pushing the screen down, it never completely closes.
It also appears that the screen is leaning somewhat to the right, and I assume this is connected to the hinge problems. Drew a red line over the image below to show this.
As for the left hinge, nothing bulges out; it seems to have slanted, however.
Any explanation for the cause of these problems? What specific parts have been broken? Possible fixes? Any help would be greatly appreciated.
