Chosen Solution

I lent this laptop to a family member (the fans were loud before but they went on and off every five minutes then and now its constant lol) and when they gave it back the back corner was very flimsy and the entire left side of the rear casing of the keyboard is sort of cracked open, but the computer works still works fine and i have no idea how this happened as it was given back to me in this condition. I have unscrewed and re-screwed the screw on the back on, but it didn’t help. does anyone have at least a guess on what is wrong? (don’t mind the crappy camera quality as my iphone 7 is broken and had to use a different device as i refuse to submit to apple trying to force people to get new iphones every year lol) also i think it may be a pin inside knocked loose or a dent that the casing overcame but the side casing might have not and caused this pushing out of the back casing, or the battery is swelling .-. edit i have removed the rear casing and something is wrong with the hinge in this photo .-.

when i first unscrewed it the hinge popped out aggressively before i got to pull the cover off lol @oldturkey03 I FOUND OURT WHATS WRONG YAYYYYY a screw holding the hinge is loose .-. the thing holding the screw isn’t connected to the computer and where it should be is a hole straight to the bottom of the keyboard .-. note: it only bends while its closed and closing becuase the loose screw is pushing as it does not want to close also the fans are not loud anymore after putting case back on?????? weird lol also when i first put the case on, the flash for the camera was on until i powered it down, does anyone know what was that about????????

@timtomissus time to take it apart and to have a look at it. It won’t be the battery, because that is at the front. This could more a hinge vs cover damage. Use something like this guideDell Chromebook 11 CB1C13 LCD Hinged Assembly Replacement to work on it. once you can identify more of the damage post some good pictures so we can help you further if needed.
