@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 [guide|127571|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.
