Answer to "Why won't my Nvidia Shield K1 charge at all"The iFixIt instructions for the NVIDIA Shield Tablet are flawed all the way through. Some of the end users’ comments are very useful and necessary to read before attempting to open this device. The battery is so difficult to remove that it’s impotysny to have a replacement battery handy. You don’t want to mess with Lithium Polymer. Even with hot air to soften the glue and a lot of patience, it’s still very very difficult to remove. You’ll need a hot air workstation to replace the USB connector. You will also need to have the replacement part. None of these are listed in the iFixIt article, which is the worst I’ve ever read.
