cuts off when I take off charging wire

@brianveill62366 if it turns off when you disconnect your power cable, it is the battery. Either the battery itself has failed (have you ever changed it) or the power circuitry has failed (unlikely). Try a new battery first.

We will need to know the exact model number for your Cambio but something like this video should work for you.

While you work on your tablet, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
