Not every repair is worthwhile and not every notebook is structurally grateful. But many defects are less dramatic than they first appear. If you check the warranty, calculate the costs and approach the matter in a structured way, you will at least gain clarity. It's often just a wearing part and you won't end up with a rubbish bin or a bill for a new device.
