Just fell off my bike with my MSi GL65 on the backpack and due the impact one of the superior corners of the screen chassis got a bit bent, luckily it didn’t broke the screen, but a light leak is appreciated. So, anything would happen if I leave it untouched? or should i teardown the screen in order to unbent the chassis?

Hard to say. If the lid opens and closes then you might be able to leave it be. Can you post a picture of the damage?
