A broken laptop hinge can render your laptop useless. If your display monitor won't stay open or feels loose, it's time to replace the hinges. Replacing the hinge can give your laptop a new life and save you the expense of purchasing a new one. Before getting started, keep a few things in mind. Replacing the hinge will require you to open up the inside of your laptop, which will void your warranty if it is still under one. Also, laptop disassembly varies greatly by manufacturer. These instructions are only general instructions. If possible, try to find the service manual for your specific laptop.
Contact the manufacturer of your laptop to order replacement parts. When you call or email, have your model number and serial number on hand. If you can't get parts from the manufacturer, contact local computer parts retailers to see if they can acquire the necessary parts for you. If that doesn't work, look for parts on eBay or other online sellers.
