Power adapter isn't connecting.

Tamara Zeno when you say it is not connecting , do you mean physically not connecting or just not charging. You do want to go ahead and measure the output of your AC adapter and see what you are getting. If the AC adapter supplies proper voltage (DC 20V) you want to go ahead and disassemble it. Use this guide Lenovo Yoga 3 14 マザーボードの交換 to work on it. Check the DC-in jack and make sure it is still properly connected etc. Post some images of what it looks like and how it connects with your question, that way we can see what you see. Use this guide iFixitでの質問に画像を追加する方法 for that.
