How do you fix the headset jack

@largesushi that jack is soldered to the motherboard. So, if you want to replace it, you will have to remove the motherboard first. Use something like this guide to do so. Now you have to unsolder the old port and replace it with a new one. The problem you might be run into is finding a proper replacement. You can always check places like mouser. com, digikey.com or Jameco.com as well as others for a part that might fit. Ultimately its a lot of work but it can be done. May be you want to consider a USB audio adapter to use for your Razer Blade.
